The PROTIG 201L AC/DC is the professional TIG welding solution for joining all types of materials up to 4 mm thick (steel, stainless steel, aluminium, copper or titanium).
It offers very high precision across many fields such as craftsmanship, maintenance and pipework.
Equipped with a water cooling unit, it allows the use of more ergonomic TIG torches
6 TIG AC/DC welding processes
TIG DC: Ensures quality welding on all ferrous materials such as steel, stainless steel, as well as copper and its alloys, titanium…
Pulsed TIG DC: Controls the temperature of the weld pool, limits distortion and thus enables the joining of thin sheet metal from 0.3 mm.
TIG DC Spot: Pre-assembles ferrous metal parts by tack welding
TIG AC Easy: Simplifies use of the welding machine thanks to predefined parameters. The user only selects the diameter of their tungsten electrode on the interface
TIG Standard: Dedicated to welding aluminium and its alloys (Al, AlSi, AlMg, AlMn…). Alternating current ensures preliminary cleaning of aluminium for a quality weld.
TIG AC Spot: Pre-assembles aluminium parts by tack welding.
2 coated electrode welding modes
MMA Standard: Accepts basic and rutile electrodes up to Ø 4 mm
Pulsed MMA: Facilitates vertical upward position welding (tubes/pipeline...).
Usage assistance for the welder
2 ignition types: HF contactless or LIFT for electrosensitive environments
3 trigger management modes: - 2-stroke: hold the trigger throughout the weld.
- 4-stroke: to start welding, hold the trigger once then press it again to stop welding.
- 4T "LOG": the operator can switch at any time between 2 welding currents with a brief trigger pulse (hot current and cold current)
MMA welding assistance: - Antisticking: reduces the risk of electrode sticking when in contact with the workpiece
- Hot Start: facilitates arc ignition and is adjustable according to metal type
- Adjustable Arc Force: regulates arc length variations
VRD (voltage reduction device): welding current is delivered only when the electrode is in contact with the workpiece (not activated by default).
• Memorization of up to 50 programs per process
• Current/voltage display after welding (verification of compliance with WPS/WPQR)
and Connectivity for remote controls (foot pedal, manual remote control)
