Kemppi's advanced welding processes: TIG and stick welding (MMA)
8 December 2025
In TIG welding, process development has mainly focused on modifying the current modes in different situations. In practice, this means variations of pulse and AC welding, as well as ignition or tack welding. In the case of pulse welding, the welding machine user has numerous choices, as the adjustment possibilities for these process variations are highly versatile.
