How did the Dual Maverick 200/200X get its name? When you glance at the front panel of this diesel engine-driven welder, you might start seeing double: two front panels and two sets of output lugs. As the name implies, the Dual Maverick 200/200X is a dual-operator welding power source. The 24.8 horsepower water-cooled Kubota diesel engine in the Dual Maverick has the capacity to allow two welding operators to weld independently of one another.
The alternative is to supply each welding operator with their own engine-driven welding machine, but this approach has drawbacks. Placing this extra equipment on the jobsite creates additional clutter and requires additional maintenance. Likewise, the one welder/one welding machine approach is less fuel-efficient. Lincoln Electric claims that a multi-user welding machine like the Maverick Dual 200/200X can reduce fuel and maintenance expenses by up to 33% per 1000 hours, which equates to approximately one year of “typical” use.
When thinking about renting welding equipment, many contractors imagine visiting a local hardware shop with a small selection of soil compactors and other basic items. In reality, today’s rental solutions are nothing like that. You can find high-quality precision machinery maintained in optimal condition, from plasma cutters to TIG rentals
With professional welder rental, companies in countless industries are able to reach their goals on time and within budget:
Many businesses perform welding tasks every day, including parts manufacturers, vehicle makers, construction businesses and repair shops. People who enjoy do-it-yourself projects can handle automotive tasks or home repairs with a good arc welder. Thanks to welder rental options, you don’t even need to purchase welding equipment to get the job done.
Two popular types of arc welding equipment are metal inert gas (MIG) welding and tungsten inert gas (TIG) welding. What are the differences? How can you decide whether MIG or TIG welding is the right method for your application.
MIG Welding Process
MIG welding utilizes a welding gun with a machine-fed consumable wire. This metal wire serves as the electrode and provides the filler material for the weld at the same time.
While you work, the MIG welder delivers inert gas (usually argon) to shield the weld pool and protect the metal from contamination. The MIG welding gun automatically feeds more wire into the molten pool as you advance, so this option provides “what-you-see-is-what-you-get” welds that are easy to start, direct and control. (more…)
If you’re looking for a portable, hassle free, full-featured spool gun solution for your steel or aluminum welding projects, look no further than Lincoln’s Magnum PRO 250LX GT K3569-2 spool gun for you next in-field welding job. The Magnum PRO 250LX GT connects directly to Red-D-Arc’s new GX330XL (and Lincoln’s Ranger 330MPX) without the need for additional adapters or control boxes. It’s simply a matter of attaching the gas hose, attaching the 7-pin control cable, and attaching the power cable to the output studs for .025”, .035” steel wire welding or .030”-.035” and 3/64” aluminum wire welding.

How do I prevent wire feeding problems when using MIG welders (GMAW) or flux-cored arc welding (FCAW) processes?
Wire feed problems with a MIG welder can be caused by a variety of circumstances. Some of the most common reasons for wire feeding issues include:
Drive roll tension with the MIG Welder: The drive rolls that push or pull the wire through the system have a tension that is either too great or too little. Adjust the spring pressure until the tension is appropriate.
Drive roll size: The drive rolls may be the wrong size. For instance, if 1.3 mm drive rolls are being used to move 0.9 mm wire, slipping will most likely occur.
Drive roll type: Some wire requires specific kinds of grooves for optimal feeding. Flux-cored and metal-cored arc welding wires typically require V-groove drive rolls that are knurled. Aluminum wires require a smooth U-shaped groove.
Drive roll condition: Worn drive rolls will be ineffective at moving a wire through the MIG welder system.
Liner size: If a liner is too small for the wire it will not feed. If the liner is too big, the wire may have too much freedom to twist inside of it, causing an unpredictable feed.
Liner type: For most wires, steel liners work excellent. However, some wires, such as aluminum, require a nylon liner to help ensure proper feeding.
Liner condition: A worn liner will be detrimental to wire feeding. Replace the liner if it is worn or damaged.
Contact tip size: A proper contact tip size should be used. If the tip is too small, the wire will not feed; if the tip is too large, wire feeding and electrical conductivity may be negatively affected.
Wire condition: Not all wire manufacturers put out the same quality product. Some wires may have thin and thick spots as well as lubricants that can cause poor wire feeding.
Earlier this year, Red-D-Arc delivered several of our MIG/MAG 4-pak and 6-pak multi-operator welding packages to Heerema Fabrication (HFG) for their yards in Zwijndrecht and Flushing, Holland. HFG manufactures complex steel structures for use in the offshore oil and gas industry.
In addition to maintaining high-quality welding standards, HFG was able to increase both worker productivity and safety by employing Red-D-Arc’s multi-operator packs for the welding processes at their fabrication yards. The packs include six welding power sources and wire feeders with gas lines to accommodate up to six individual welders – and each welder has his own 115VAC power supply as well as an airline that provides filtered breathing air to the welder’s helmet. All input power, shielding-gas and breathing-air connections are made via single connections in the pak’s enclosure in order to simplify hook up as well as enhance portability.
“With the multi-packs our operators can get set up faster and start welding immediately. The time savings and increased efficiency easily covers the cost of the packs.”
After receiving their initial order of 6-paks, HFG placed a second order for 4-paks, having recognized the benefits of the system.
Red-D-Arc 4-Pak and 6-Pak MIG/MAG Multi-Operator Welding Packages are available for rent, lease or purchase. Contact Sales to learn more.
