4 in 1 New STAHLWERK CT 520P DC Inverter MMA/TIG/ Welding Machine Welder Plasma Cutter Cutting Machine w/ Pulse Function
2 Stroke and 4 Stroke - circuit:  at 2-stroke, the torch button of the TIG tube package  has to remain pressed and held. Once the button is released the arc is extinguished. At 4-stroke the arc remains stable after pressing. Only by pressing the torch button the arc is extinguished and the current reduction occurs automatically with the gas-run time. Professional settings in which you achieve results of a quality that impress even the professional user.Function 2: Air Plasma CUT- 50 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 3:Manual metal arc welding (MMA) with 200 amp:Features:• MMA: manual metal arc welding.• TIG tube package with ball joint and with integrated control switch.• Adjustable welding current: adjustable between 0 and 200 A (for pulse mode upper value).• Automatic slow current reduction after switching off the tube package. Adjustable between 0 - 10 seconds (makes a clean finish, there are no blowholes).• Gas preliminary time:: important to protect the weld from air supply and to create a gas atmosphere• Gas post flow time: saves the tungsten electrode against excessive wear. and protects the weld from oxidation.• Pulse frequency: adjustable between 0,5 - 200 Hz• Pulse current: adjustable between 10 % - 90 %• Pulse intensity of welding current: adjustable between 20% -60%• Gas magnetic valve: will open only when pressing the hand torch or the foot pedal and closes when the welding process is completed.• Automatic cooling ventilators.• Overheating protection: turns on when the device is overloaded. A red control light turns on, and goes off when the device is cooled.                                                                                                  Function 1: DC TIG 200 A  • Gas post flow time: saves the tungsten electrode against excessive wear and protects the weld from oxidation.
