94048088 - Arcair K4000 Replacement Upper Arm Assembly

Restore Your Gouging Torch with the Arcair K4000 Upper Arm

Is your gouging torch losing its grip? The Arcair 94-048-088 Upper Arm is the direct replacement part you need to fix broken or worn-out lever mechanisms on K4000 and K5 manual gouging torches. Carbon arc gouging is a tough process that puts immense strain on torch components. The upper arm is a critical moving part that helps clamp the carbon rod in place; if it becomes bent, cracked, or eroded, your ability to control the gouge is compromised. This authentic replacement part ensures you get back to cutting and gouging with the precision and control you expect from Arcair equipment.

Designed for the professional welder and fabricator, this upper arm fits perfectly into the torch body assembly. It works in conjunction with the lever and spring to apply the necessary pressure to the rotating head and jaw. A compromised upper arm can lead to dangerous arcing inside the torch head or a loose electrode that poses a safety hazard. By swapping out the damaged arm with this new 94-048-088 unit, you extend the service life of your expensive torch handle rather than replacing the entire unit. It is also the correct replacement for the RADNOR™ Pro 4000 torch, making it a universal fix for the most common heavy-duty gouging tools in the industry.

Installation is straightforward for those familiar with torch repair. The part measures approximately 8.8 inches in length and is engineered for the specific geometry of the Angle-Arc series. Whether you are removing welds, preparing plate edges, or cleaning castings, a reliable torch is non-negotiable. Don't let a faulty mechanical arm slow down your workflow. Invest in genuine Arcair repair parts to ensure consistent air flow, electrical conductivity, and mechanical strength in your gouging operations.
