As successful aluminum welding requires a stable arc, a Pull (Push-Pull) MIG gun ensures a steady, consistent, and reliable wire feeding for soft wires like aluminum or brazing wires, even at long feeding distances. This welding gun has been specially designed to weld thin aluminum wires, allowing for reliable wire feeding, even with long cables on the gun. With the least amount of frictional loss, the optimal wire feed is made possible by a heavy duty, powerful pull motor that allows precise speed control.
