• Using an original mathematical control model to digitally control the welding machine voltage and current waveform, the welding performance is good (good welding arc starting, stable arc starting, less spatter).
• Built-in expert database and unified control mode automatically match the best data according to different welding specifications, making it easy to achieve fast and stable welding.
• Built-in large-capacity data memory, which can store 50 sets of user's own process specifications, user's function settings, etc..
• This series of welding machines has functions such as manual welding, gas shielded welding, single pulse, double pulse, etc..
• Strong ability to withstand grid voltage fluctuations and can be used for generator power supply.
• The power supply adopts primary side peak current feedback control to effectively solve the IGBT overcurrent problem and improve reliability.
• Independent water tank design, you can choose to equip it with or without a water tank.
