Yes, we really welded an axleshaft together. The Premier can blast out a force to weld nearly anything, and can cut steel as well if it's cranked all the way up. Sheetmetal can also be welded if you have a deft touch and small-diameter rod. The Premier offers 115V DC power, which allows the use of power tools. This helps clean or grind the area around a weld for far superior penetration and control of the weld. The Premier also charges batteries at a high rate as well.
