Airborne contaminants can foul heat exchanger fins over time resulting in reduced efficiencies and heat exchange capacity. Traditional cleaning methods such as liquid foam and caustic chemicals have fallen out of favor in exchange for more environmentally friendly technologies such as dry ice blasting.
Recently, an oil refinery in New Mexico needed to perform an emergency cleaning on their heat exchangers due to the fins being clogged. The heat exchangers were cleaned using dry ice blasting which allowed the fin banks to be put back into service immediately after the cleaning process was completed since there was no required dry-out period typically associated with wet cleaning methods (drastically reducing downtime).
In addition, since the fin banks could be cleaned one at a time, additional time was saved since the cleaning could be performed in stages, which allowed banks that weren’t being cleaned to remain in operation. The dry ice blasting process proved superior for cleaning the radiators, recapturing improved heat transfer efficiencies, negating waste creation conventionally associated with maintenance cleaning, reducing containment/disposal costs, and improving heat exchanger operation and safety.
The Red-D-Arc team provided a complete solution for the project including: rental dry ice blasting equipment, portable compressors, dry ice supply, as well as on-site support personnel to provide training and application advice. Dry ice blasting provides a higher quality of clean, reduces the risk of damage, uses no water, aligns with sustainability models, and consumes recycled CO2 byproduct in the form of dry ice making it a carbon neutral option in today’s increasingly environmentally conscious world. Heat exchangers aren’t limited to the oil and gas sector, and are used across a wide range of industries.

As the State of California continues their pursuit for clean air coupled with some of the strictest emissions regulations in the US, Red-D-Arc Powerentals has responded with the addition of HIPOWER 325 kVA T4F towable generators, a new 4000 amp distribution panel and a new rental-asset-specific GPS feature to their rental offering.
With these additions to their lineup, Red-D-Arc is now competitive through the 1+ megawatt rental offering which is achieved by paralleling combinations of 190 kVA, 240 kVA and 325 kVA generators that offer the advantage of enhanced fuel efficiency compared to a single, 1 megawatt unit for applications with fluctuating power requirements.
By demonstrating this new arrangement and the fuel savings associated with this offering, David Rodriguez, Red-D-Arc’s Generator Specialist for our West District, was successful in winning Tier 4 Final-only projects that required a minimum of 1 megawatt of power. The rentals commenced with the delivery of four 325 kVA units, accompanied by a distribution panel and the necessary power cables to complete the job.
With the addition of ZTR GPS fleet tracking asset management telematics, we were able to provide the customer with various operating data including load percentages, GPH (gallons per hour) fuel consumption, as well as bringing on and shutting off generators as the power requirements fluctuated. The GPS provided data to support the customer’s fuel savings and also demonstrated continuous real-time review of operating conditions which enabled our team to remotely diagnose a shutdown related to the customer’s equipment, resulting in savings in time and manpower, as well as travel to and from the restricted-access job-site.
Several other contractors working on the project asked how and why this unique setup was in place and, as a result, additional rental opportunities are in the works! As fuel prices continue to climb, opportunities to reduce fuel consumption are becoming more important than ever.
Aluminum alloys continue to gain popularity in metal fabrication worldwide due in part to the ease with which these alloys can be fabricated—bent, welded, and most importantly, cut. The ease at which aluminum can be cut to shape and size can have a big influence on the cost and quality of subsequent operations and the final component itself. As with steel, the use of plasma arc cutting (PAC) on aluminum alloys is a popular choice for quickly producing high-quality cuts.
Speed is one of the greatest justifications for plasma arc cutting aluminum over mechanical cutting methods. Laser cutting can certainly exceed the speed of plasma but is not without its own process disadvantages. Waterjet cutting certainly has advantages over plasma from a metallurgical and edge quality perspective. Instead, cutting aluminum with plasma provides an excellent balance of speed, quality, and cost. Compared to these other processes, it has a notably lower capital investment and is also simpler to implement as a handheld process for in-service repairs in both the field and shop.
Like shielded metal arc welding (SMAW, stick), Flux Core Welding (FCAW) is a popular welding process that uses the assistance of flux within a tubular wire to help produce high-quality welds. Unlike shielded metal arc welding, flux cored welding can be divided into two distinct processes: self-shielded flux-cored arc welding (FCAW-S) and gas-shielded flux-cored arc welding (FCAW-G).
Both the home hobbyist and professional welder will encounter situations where one process is advisable over the other. FCAW-G is most often used indoors, while FCAW-S is typically used outdoors. To maximize productivity and quality, welders should become familiar with the welding tools and equipment of both processes so that they can quickly setup and operate whichever process is best for their application and welding environment.
Due to the rapid acceptance and increasing demand from the steel fabrication industry for the BotXTM cobot welder, Red-D-Arc Weld Automation opened its Robotics and Automation Center (RAC) at our Mableton (Atlanta), Georgia location, on January 3, 2022.

Welding automation has been around for a while, but recently its role has grown exponentially in manufacturing. For years, the welding industry has faced a skill gap, which is expected to grow wider in the coming years. To combat this, employers are adopting automated welding equipment to increase the efficiency of weld operations.
What Is the Skill Gap?
The “skill gap” describes a discrepancy between the skills held by job seekers and the skills employers need. This leads to a paradox where there’s a large pool of applicants, but companies aren’t able to hire workers with the appropriate knowledge and skill set. This has led to increasing welder salaries as manufacturing businesses compete to attract skilled workers, and even then, many positions are left unfilled.
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.

When a major auto parts manufacturer asked an Ontario fabrication shop to weld 50,000 parts in just 2 months, they took the job immediately; then they had to solve the problem of how to get that much welding production done within such a short time time period. Read about how the adoption of welding cobots helped them deliver in this article from Shop Metalworking Technology magazine.
“If you turn this down once, you will never see a job like this again.”
Readily available power is a requirement for most businesses. In fact, power outages on construction sites and other facilities can be disastrous without a reliable electricity backup.
A dependable generator is often a requirement to power all the necessary tools on a job-site. In other circumstances, generators can be used as a supplementary or backup supply as a precaution for any incidents that cause the loss of power. Generator rentals are an easy way to protect your power at all times. (more…)
