Abstract
Kemppi in co-operation with its clients has developed a new MicroTack technology, which eases tack weld of the low-carbon and corrosion-resistant steel, accelerates the process, and improves the quality of the tack welds that results in speeding up of the further main welding. The technology is available on the new MasterTig MLS™ 3000/3003 ACDC welding apparatus, which does for welding low-carbon and corrosion-resistant steel, as well as aluminium.
