The PROTIG 201 AC/DC is the professional TIG welding solution for welding all types of metal up to 4 mm thick (steel, stainless steel, aluminium, copper or titanium). It ensures a very high level of precision in many areas such as fabrication, maintenance or piping. 6 TIG AC/DC PROCESSES Welding current : 10 to 200 A (TIG AC), 10 to 160 A (TIG DC) TIG DC - Standard : Ensures a quality weld on all ferrous materials such as steel, stainless steel but also copper and its alloys, titanium. TIG DC Pulse : Controls molten temperature, limits deformation and thus allows the assembly of thin sheets from 0.3 mm. TIG DC SPOT : Pre-assembles the aluminium parts by tacking. TIG AC - Easy : Makes the use of the welding machine easier thanks to predefined settings. The user only selects the diameter of his tungsten electrode on the interface. TIG AC - Standard : Designed for welding aluminium and its alloys (Al, AlSi, AlMg, AlMn...). Alternating current provides cleaning of the aluminium for a perfect weld. TIG AC SPOT : Pre-assembles the aluminium parts by tacking. 2 MODES OF COATED ELECTRODE WELDING Welding current : from 10 to 160 A (MMA) • MMA Standard : Accepts basic, rutile electrodes up to Ø 4 mm. • MMA Pulse : Helps welding in a vertical upright position (nozzles/pipeline). DESIGNED FOR USER COMFORT 2 types of start-up : HF (without contact) or LIFT (with contact) for electro-sensitive environments. 3 trigger modes: - 2 times: maintain pressure on the trigger throughout the weld. - 4 times: to start welding, press the trigger only once and then press the trigger again to stop welding. - 4T «LOG»: the operator chooses at any time between 2 welding currents by a short pulse on the trigger (hot and cold current). MMA welding assistance: - Antisticking : reduces the risks of the electrode sticking if it comes into contact with the workpiece - Hot Start: Assists in Arc ignition and can be adjusted according to the type of metal - Arc Force Adjustable: regulates the arc length deviations VRD (voltage reduction device): the welding current is only delivered when the electrode is in contact with the workpiece (not originally activated). ROBUST DESIGN FOR ALL ENVIRONMENTS Reinforced chassis and Anti-shock absorbant protection • Compact and lightweight design • Current/Voltage display after welding (DMOS/QMOS) • Storage of up to 50 programs per process • Connectivity for remote controls
