ELMA MIDI TIG welding sets are the answer to the professional requirements of today and tomorrow. Besides conventional TIG welding performance, the ELMA MIDI TIG welding units also are suitable for long-pulse welding, pulse-arc welding up to 200 Hz and last but not least for MIX-TIG welding.
The latter stands for a smooth positional welding performance as the result of a specially controlled change between direct and alternating current. Especially for AC welding tasks, ELMA FLEX WAVE permits the maximum reduction of electrode consumption and welding noise.
- MIDI TIG DC
Direct current welding sets for the professional welding of non-corrodible and acid-resistant steel, of copper, titanium, nickel, brass as well as of unalloyed and low-alloy steel.
- MIDI TIG AC/DC
Welding unit for direct and alternating current (AC/DC) for perfect results, also when welding aluminium and aluminium alloys.
General features
- Stable arc
- Maximum reproducibility and setting accuracy
- AC-welding without HF stabilizing device, i.e. without superimposing high-voltage pulses during the welding process
- Well-balanced ratio of cleaning effect and penetration satisfying the precondition for perfect welding seams

- Alternating current balance
- Hot-start-device (Stick electrode)
- Dynamic ARC FORCE for stick electrode welding
- Insensitive to supply voltage variations, reproducible and transmittable properties (static and dynamic)
- 2-cycle- / 4-cycle- / spot welding/ pulse welding
- Slope function (Slope-up / Slope-down)
- Maximum process safety due to the ELMATECH control system of static and dynamic properties with virtual machine
- Sequence control automatically assigning an ignition (PZ), a welding (PS) and a craterfilling program (PK) to each welding program
- Long duty cycle
