The PROTIG 201 AC/DC represents 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 in many fields such as craftsmanship, maintenance or 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 deformation and thus allows the joining of thin sheets from 0.3 mm.
TIG DC Spot: Pre-assembles ferrous metal parts by tack welding
TIG AC Easy: Simplifies the use of the welding unit 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 the aluminium for a quality weld.
TIG AC Spot: Pre-assembles aluminium parts by tack welding.
2 stick electrode welding modes
MMA Standard: Accepts basic, rutile electrodes up to Ø 4 mm
Pulsed MMA: Facilitates vertical up-position welding (pipe fittings/pipeline...).
User assistance for the welder
2 arc ignition types: HF non-contact or LIFT for electrosensitive environments
3 trigger modes: - 2T: maintain pressure on the trigger throughout the weld.
- 4T: to start welding, hold the trigger once then press again to stop welding.
- 4T "LOG": the operator can switch between 2 welding currents at any time with a brief pulse on the trigger (hot current and cold current)
MMA welding assistance: - Anti-sticking: reduces the risk of electrode sticking when in contact with the workpiece
- Hot Start: facilitates arc striking and can be adjusted according to the type of metal
- 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).
• Memory for up to 50 programs per process
• Connectivity for remote controls (foot pedal, manual remote control)
• Current/voltage display after welding (verification of compliance with WPS/WPQR)
• Reinforced casing and anti-shock pads
