OVERVIEW

Master the Sub-Arc Process by Hand

When you need the massive deposition rates of submerged arc welding but the flexibility of a handheld tool, the Lincoln Electric K52106-7 Gun Assembly is your go-to solution. Built for the serious welder tackling heavy plate, this 550-amp beast lets you lay down serious metal without being tied to a track system. Whether you are welding bridge girders, heavy equipment frames, or pressure vessels, this gun delivers the power and reliability Lincoln is famous for.

The 7-foot cable gives you enough room to move around large workpieces without getting tangled, while the gun's design keeps the flux flowing smoothly right where you need it. We know that sub-arc welding can be tough on equipment, which is why Lincoln built this assembly to last. The handle is comfortable enough for all-day use, but tough enough to survive the shop floor. No more struggling with makeshift setups; this is a purpose-built tool that puts the power of sub-arc in the palm of your hand.

Forget about smoke and spatter—the submerged arc process keeps the arc covered, and this gun makes it easy to maintain that cover manually. It’s perfect for those long, straight fillet welds or filling deep grooves where a tractor just won't fit. Hook it up to your Lincoln feeder, load up your flux, and get ready to experience high-efficiency welding with the control you demand.
