Sturdy construction, designed for pipe welding, the TIG 220 DC is a high quality welder for mild and stainless steels (TIG and MMA). Its ergonomic interface makes settings adjustment easy and intuitive. Clear and intuitive interface. Quick adjustments on the front panel : - hot / cold current - pulse frequency - downslope time - pre-gas / post-gas - upslope time - welding current OPTIMISED DC WELDING TIG DC : continuous current for ferrous metals. TIG DC Pulse : reduces heat distortion of the workpiece. SPOT : fast and precise spot welding, ideal before welding thin metal sheets. 2 types of start-up : HF (without contact) or LIFT (with contact) for electro-sensitive environments. trigger modes : 2T, 4T and 4T LOG. Automatic detection of the torch : compatible with trigger, double button and potentiometer torches. AIP (Adjust Ideal Position) : helps to position the torch before welding (4T & 4T LOG modes). MMA WELDING - MMA : Basic rutiles and rutile electrodes (up to Ø 5 mm). - MMA Pulse : Developed for pipe welding as well as vertical up welding. STURDY - Reinforced panels & shockproof rubber pads on the external body. - Light (12.5 kg), compact and easy to move on-site. ERGONOMIC INTERFACE - Displays current/voltage during and after welding (DMOS/QMOS). - Save 10 programs for each process, for repetitive tasks. - Food pedal and remote control (optional). HIGH-TECH POWER SUPPLY - Flexible Voltage power supply, the machine will work on a single phase power supply from 85 to 265 V. - PFC technology (Power Factor Correction), the electrical power supply usage is optimised for up to 30% energy savings. WATERCOOLING (optional) - Automatic, the cooling unit is controlled by the machine. - Easy connection thanks to the two Plug & Play connectors. - Water cooled torch, for better comfort and access to difficult areas.
