In addition to the conventional TIG welding, welding with the VARIO TIG welding systems from ELMA-Tech means Long Pulse Welding, pulse welding up to 200 Hz and MIX TIG welding.
MIX TIG welding stands for unproblematic welding in constrained positions by specially controlled switching between AC and DC. In particular in the AC area, ELMA FLEX WAVE guarantees maximum possible reduction of electrode wear and welding sounds.
The VARIO TIG is the connection of functionality and the latest inverter hybrid technology. Available as a direct current (DC) or as a AC/DC systems, there are almost no limits to the applications.
Device types
- VARIO TIG DC systems: For professional welding of carbon and low alloy steels, stainless steels, copper, titanium, nickel, brass, etc.
VARIO TIG 250 DC
