Function 1: DC TIG 120 A • Gas post flow time: saves the tungsten electrode against excessive wear and protects the weld from oxidation. • HF Ignition: high-frequency contactless ignition to the metal. Function 2: Air Plasma CUT- 30 The professional plasma cutter combines the advanced TOSHIBA MOSFET inverter technology. By V - MOSFET technology, the device has a high duty cycle of 60%. For about 13 years, this technology is proven to the IGBT system Switch on the hand grip (similar models work with cable ties) Cutting power up to 12 mm, depending on material: • Construction steel ST37 up to 12 mm • V2A up to 8 mm • Aluminium up to 7-8 mm Function 2: Air Plasma CUT- 30 Function 3: Manual metal arc welding (MMA) with 120 amp: • 60% Einschaltdauer bei 120 Ampere !!! What types of electrodes can be used: 1) Unalloyed steels TYP R3, A5 und AR 7 2) For sheets up to 3 mm electrode R3 - diameter 1,5 mm, 2,00mm, 2,5 mm. 3) For stronger materials electrode R3 - diameter 3,25 mm and 4,00 mm. 4) V-welds and pipes/tubes should be welded with electrodes A5 and AR7Features: · Antistick: prevents annealing of the electrode (less consumable electrodes), because the power is immediately terminated. Hot Start: automatic voltage increase at the start · Lift Ignition: in contact with the workpiece · Automatic cooling ventilators·MMA welding with rutile and basic coated electrodes for all un-and low-and high-alloy steels, nickel and copper alloys up to 4,2 mm Specs:Rated voltage AC 220 V ± 10%Input frequency 50 / 60 HzInput current 4,5 KVADuty cycle at 120 A(for Plasma cutter at 30 A) 60%Duty cycle at 150 A(for Plasma cutter at 30 A) 100%Display of output current/ For Plasma cutter 10 ~ 200 A /10 - 50 AOvercurrent protection 16 AWeight 12 kgDimensions 423 x 173 x 273 mm weld Intensity 0,8 bis 10 mmCutting power 12 mmSafety class IP 21
