5 IN 1 Multifunctional machine-SUPER225 is an AC TIG/DC TIG/pulse TIG/cutting/MMA Multi-function welding which adopts the most advanced IGBT inverter technology.Integrated cutting and welding, easy to operate. 2T/4T (TIG) - determines the control of the operating mode and provides extended control over the current flow. In 2T mode, high-frequency (HF) ignition remains active until the button on the torch is released. In 4T mode, the arc is ignited after pressing and releasing the button once. After pressing and releasing the button again, the ignition is terminated. Some functions, such as current reduction, are only possible in 4T. Extensive pulse function - TIG PULS - prevents materials from burning through and reduces deformation due to heat, especially suitable for welding thin plates whose material may only be heated a little. Adjustable parameters are: Pulse current, pulse width, pulse frequency,. Gas delay protection: When welding is stopped, automatic delay of 2-10S prevents metal oxidation and makes the surface smooth and shiny Remote Control: You can use a 5PIN pedal to remotely adjust the voltage and current, saving time and effort., Manufacturer: MOOILKO
