The manufacturing industry is in distress. There is a shortage of skilled talent and this gap is only widening. While manufacturing companies are able to make goods faster and cheaper than ever, there is a growing lack of skilled manufacturing employees to ensure that production continues. Industry projections from Deloitte and the Manufacturing Institute, among other industry analysts, predict that over the next decade, more than 2 million manufacturing jobs will go unfilled across the U.S.
This decline in skilled manufacturing workers is a result of two issues:
1. A very large portion of workers at or near retirement age
2. Incoming generations that are far less interested in the manufacturing industry
Welding is perhaps one of the susceptible areas in manufacturing to this trend because of the skill welding requires. The lack of skilled welders is causing large inefficiencies in the manufacturing industry due to under-staffing and also causing pay rates of skilled welders to go higher and higher. Since it does not appear that upcoming generations will have a large participation rate as welders, the solution to the problem will likely be solved by the implementation of automated welding solutions.
Automated Welding Solutions That Deliver ROI
Automated Welding Solutions Come in a Variety of Forms
Although full-auto arc welding machines are part of the remedy, they are not a panacea. Fully-automated welding solutions often require high capital expenditure, require expensive skilled programming personnel, and pose significant safety risks if not set-up properly. The trade-off between the benefits of fully-automatic welding machines and their disadvantages led to the development of a new type of automated welding solution: the welding cobot.
Enter: The Cobot (a Collaborative Robot)
The name cobot is short for “collaborative robot”. The increase of cobot development and deployment is revolutionizing the manufacturing industry. Welding cobots are unique welding tools that hold many advantages over other automated welding machines, especially traditional welding robotic systems. Cobots have special mechanisms and move in such a way that enables them to require little to no safety fencing. While the potential for increased safety without extra costs is an excellent benefit, the most important benefit of cobot use in an automated welding cell is the reduced costs associated with installation and programming.
Robotic Welding Just Got Easier
Traditional automatic robotic welding machines require a high level of skill to program. Oftentimes many years of knowledge and experience are required to set up an automated weld cell; for this reason, many companies elect to hire contractors to do this work for them, adding to the already high cost. With cobots, the programming of the machine is much simpler. The programming software is engineered to be user-friendly, vastly decreasing the instruction time required to train a programmer. This not only lowers the initial costs of programming, but also enables a cobot to have a high degree of flexibility. The decrease in programming time and safety equipment and the increase in flexibility typically result in a very short ROI timeline and reduce the dependency on skilled welders and automated welding robot programmers.

Red-D-Arc understands that many of our customers are not immune to the trends affecting the manufacturing industry as a whole. We know that maintaining a technological advantage is key to success. In order to help our customers fight increasing costs associated with the decline in skilled welding employees and complicated automatic welding machines, Red-D-Arc offers collaborative welding robot solutions.
The BotX-Welder is our cobot product solution for our customers. The BotX-Welder package comes with a UR10e cobot arm created by Universal Robots, a leader in cobot development. In conjunction with this robot arm, the Bot-X Welder system also comes with an XMT350 MPa MIG welder and S74 MPa Plus wirefeeder, both made by Miller Electric. A MIG torch and a welding fabrication table are also included to complete the cobot welding cell. While the hardware is state-of-the-art, it is the software in the BotX Welding cell that truly sets it apart. The robot arm in the Bot-X automated welding system is controlled by the Hirerobotics application, which can be used with either iOS or Android operating systems. The Hirerobotics app is much easier to use than a traditional automatic robotic welding machine teach pendant.
A Welding App With All The Robotic Welding Routines You Need
What’s more is that the Bot-X Welder also comes with an expansive library of welding routines, with weld parameters made to fit almost any application. Welding can be automatically monitored and recorded through cloud connectivity. This allows remote users to view weld data from anywhere in the world as long as they are connected to the network. The cost and risks of new technologies are often high. Red-D-Arc eliminates the risk of failed robotic welding implementations by only charging our customers by the productivehour when using the Bot-X Welder. This enables users to try the machine out, use it as much as they need it, and get rid of it when it the work slows down. This probably won’t be a problem, since you’ll be able to keep customers happy with a quick rate of output and very high weld quality. The pay-as-you-go system is much easier and more cost-effective than the traditional hiring and firing of personnel.
Maintaining a technological advantage is key not only to prosperity in the manufacturing industry, it is essential to survival. As more and more efficient means of weld production are developed and as the number of skilled welding laborers decline, the pressure is on to adapt.
Red-D-Arc has always and will continue to support our customers through industry shifts. The Bot-X cobot welding system is another way we help you keep ahead of the competition.
There may only be one thing better than eating delicious barbecue cooked slow and low on a smoker, and that is eating some delicious barbecue that you cooked slow and low on the barbecue smoker that you made. Making barbecue smokers has long been a favorite hobby of backyard cooks and professional pitmasters alike.
While one may feel comfortable with procuring the material, cutting out the doors, and forming the metal of the smoke chimney, uncertainty may arise when it comes time to join these materials with a welding machine. Therefore, it is important to know at the start what type of welder will be required to make a BBQ smoker.
Shielded Metal Arc Welders (Stick or SMAW)
Shielded metal arc welders, colloquially known as stick welders, are an excellent way to weld together the components of many types of BBQ smokers. Stick welders, when compared with other welding power sources, are very simple. They do not require shielding gas, they do not require advanced electrical waveforms, and they don’t require a wire feeding system. All of this makes for a very robust and relatively portable welding system.
Inverter power sources, like the ES275i stick welder, are especially mobile because they do not have big, heavy transformers, making them much more carryable. This is nice if you have multiple projects ongoing. Another advantage of stick welders is that they can be used to join dirtier material because of the flux coating on the electrodes that the machines use. The reduced amount of time spent cleaning off mill scale and rust prior to welding allows one to get to that first slab of St. Louis spare ribs that much quicker. Stick welders such as the ES275i can also join very thick materials. Coming in with a maximum amperage of 275, the ES275i will be capable of welding BBQ smokers made of the thickest steels.
Stick welders are not the answer for all BBQ smoker welding activities though. If thin materials, especially those less than 1.5 mm, are to be welded, then stick welding could be troublesome because even the small electrodes are somewhat large when compared with other welding processes.
If weld spatter is a concern, which it may be if a paint or powder coating is going to applied after fabrication, then a stick welder may not be the best choice as the stick welding process can expel a lot of molten metal from the weld puddle. The weld spatter can be taken care of by proper post-weld cleaning though. Finally, if non-ferrous or stainless steels are being welded, it may be better to use an alternative welding process.
Gas Metal Arc Welders (MIG or GMAW)
Gas metal arc welders, less formally known as metal inert gas (MIG) welders, are another excellent category of welding machine to use when assembling a BBQ smoker. MIG welders are similar to stick welders in the sense that the electrode is also the weld filler metal, but MIG welders do come with other added complexities. For one, they require a wire feeding system. This wire feeding system could be internal like that of a Lincoln Power MIG 180C, or external such as an LN25 wire feeder combined with an EX360 welding power supply. MIG welders also require shielding gas, unlike stick welders.
MIG welders are excellent choices to build a BBQ smoker with because of the amount of skill it takes to learn how to make a MIG weld, which is arguably less than that required to stick weld or use other welding processes. Also, MIG welding is considered a fast travel speed process when compared with many other welding processes. If the BBQ smokers are getting made in large numbers in a production setting, then a MIG welder may be an excellent way to increase productivity. MIG welders are also better suited than stick welding to join materials other than carbon steel together.
If the BBQ smokers are getting made in large numbers in a production setting, then a MIG welder may be an excellent way to increase productivity.
MIG welding machines do come with several disadvantages though. In addition to the added complexities over stick welding mentioned above, MIG weld can also be a little more limited in the material thicknesses it can join together than stick welding because of its smaller electrode size. MIG welders, especially those without advanced pulse waveforms, can leave weld spatter on the BBQ smoker. A MIG welding machine like the Lincoln Power Wave 455M/STT has pulse welding waveforms that can alleviate this concern. Furthermore, MIG welding machines, while they can join materials other than carbon steel together, they are not as capable of doing so as the next type of welding machine this article highlights below.
Gas Tungsten Arc Welders (TIG or GTAW)
Gas tungsten arc welding, often called tungsten inert gas (TIG) welding is a process that can also be used to manufacture BBQ smokers. Of the three welding machine types mentioned in this article, TIG welding machines are perhaps the most complex to use. They require the manipulation of a torch with a non-consumable tungsten electrode and a shielding gas in one hand, and in the other hand a filler metal rod in order to add weld metal reinforcement. The amperage can also be adjusted by the welder on the fly, typically by use of a foot pedal. TIG welders can be light and transportable like the Miller Maxstar 200 SD inverter power source or big and heavy like the Miller Syncrowave 250 DX transformer power source.
TIG welders provide many benefits when assembling a BBQ smoker. One of the greatest benefits is their ability to join materials other than carbon steel. Aluminum, stainless steel, even nickel superalloys can be joined using a TIG welding power source. Now, it’s unlikely that anyone will be using Inconel 625 to construct the smoky chamber that houses their prime cut of brisket, but one may want to make it out of stainless steel, or even simply add stainless steel grates to a carbon steel frame. This is where a TIG welder can really shine during the fabrication process. Another reason for selecting a TIG welder is cosmetic purposes. TIG welders, when operated by skilled welding personnel, can make very aesthetically pleasing welds. In addition, when it comes time to join extremely thin materials, TIG welders are very capable machines.
One of the greatest benefits of TIG welders is their ability to join materials other than carbon steel.
TIG welding machines may not always be the best choice, however. For one, they can be more expensive than MIG welders and barebones stick welders. Power sources like the Miller Dynasty 350 have a lot of bells and whistles that, while allowing for an incredible amount of operator control, can tend to come with a premium over the welding machines used solely for stick or MIG welding. TIG welding is also a relatively slow travel speed process, which may be fine for one-off smokers, but not necessarily suitable for a production environment. TIG welders also require a high degree of operator skill with respect to operating other types of welding machines.
…But Which One is the Best?
The best welder for building a BBQ smoker truly depends on the type of smoker being built. For most smokers, any one of these three types of welders will work just fine. Want speed? Go with MIG. Need portability? Give a stick welder a try. Welding non-ferrous or stainless steel? A TIG welder may be your best bet. Refer to the table below to see the advantages of each welder type to see which one may suit your needs best.

ArcReach® technology is an investment that results in a lot of time saved during welding operations. With most welding equipment the operator needs to walk back and forth to adjust output voltage – sometimes over hundreds of feet – multiple times during a job. This results in hundreds of wasted hours and thousands of lost dollars over the course of a large project.
ArcReach technology enables welders to adjust the voltage settings right at the point of welding
ArcReach technology enables welders to adjust the voltage settings right at the point of welding instead of walking all the way to the power source and back. Even worse, if the voltage settings are “just good enough”, the operator might not bother making the trip, resulting in lower quality welds.
How Does Arc Reach Work?
With ArcReach®, the digital signal carries voltage information via the weld cables. The connection happens automatically. The ArcReach software in the power source receives the signals it receives from the remote accessory or wire feeder and adjusts the output as indicated by the operator.

Powerful Clean Wet Media Blasting that Removes Almost Any Coating
If you’re trying to remove old paint, hardened epoxy, corrosion, rust or scale you want a powerful cleaning solution that’s easy to use. Wet Media Blasting using crushed glass is one of the toughest most reliable methods available.
Built Tough, Easy to Use
The Clearblast 150 wet media blaster provides powerful wet blasting in a portable package. Ruggedly built to take on the toughest blast cleaning jobs, this machine can provide up to 120psi of cleaning power for over an hour straight. The intuitive control panel is easy to understand and first-time users can get set up and start blasting within minutes. Stainless steel piping on a hard steel frame with a powder-coated finish makes this machine an excellent choice for harsh environments and repeated transport and use.
The Wet Blasting Process
1. Water is supplied by the on-board tank or standalone trailer. (uses roughly 1 pint per min.)
2. Abrasive media is added to the hopper
3. Compressed air delivers a stream of wet abrasive media to the cleaning surface like a hail of darts
Wet Media Blasting using crushed glass is one of the toughest, cleanest blast cleaning methods available.
An Excellent Alternative to Sandblasting
Dry blasting methods throw particles against a surface, pulverizing coatings and creating a lot of airborne particles which can be a health hazard and a pain to clean up. It can also damage the substrate, removing materials and compromising surface integrity. Substantial containment and cleanup are involved. Wet Blasting, on the other hand, eliminates more than 90% of airborne dust, uses far fewer blast media and is one of the safest, cleanest, greenest blasting methods available.
Many blast cleaning systems claim to be “dustless” but what we are really talking about is the reduction of airborne dust particles. If you’re using blast media and removing coatings, you’re going to have some residue. Wet media suppresses airborne dust and requires far less clean up than other blasting methods. Until someone invents a blaster that destroys matter, there’s always going to be some kind of residue leftover from a blasting job.
