Top 100: Portable Welding

Designed for use on sites where conventional welding power is not available, Broco's battery-powered GOWELD creates welds up to ½ inch thick on steel or aluminum. The 35-pound unit operates on two 12-volt batteries and uses self-shielding (flux-core, FCAW) or gas-shielded (solid, MIG/MAG) welding wire. No AC power is needed. Estimated list price: $685.
