MK Products Python LX Water-Cooled Push-Pull Gun, Lincoln 7-Pin, 50 ft
This water-cooled Python LX push-pull gun runs on a 50 ft lead with a Lincoln 7-pin connection for wide reach on aluminum jobs. It is rated 400 A at 100% duty cycle, and a rear trigger plus a built-in mechanical gas valve handle shielding gas control.
Shielding gas is handled at the gun by an integrated mechanical valve, and the trigger sits at the rear of the handle. The EZ-Lock barrel turns a full 360°, and Flex Barrel compatibility helps on welds that are hard to reach. A wire feed adjustment for right- or left-hand use is housed inside the handle, out of harm's way, and the light pistol grip is balanced for long shifts of continuous feeding. It can be paired with almost any CV or CC power source.
On argon, the water-cooled LX is rated 400 A at 100% duty cycle for aluminum work that needs a high duty cycle. It takes .030-1/16 in. (0.8-1.6 mm) aluminum wire or .030-.045 in. (0.8-1.2 mm) steel, stainless and flux-cored wire at 0-800 IPM, with a 1000 IPM option (P/N 211-0080). Its CNC-machined billet components and Ultra-Flex power cable are meant for heavy production work.
