Full function AC/DC pulse argon arc welding

Welding machine multi-purpose, can be AC/DC argon arc welding, pulse argon arc welding, manual welding. Using AC waveform control technology, multiple current parameters can be accurately controlled. Perfect function, base/peak current, arc current, pulse frequency, cleaning width and air delay time can be adjusted. The cleaning width can be accurately matched according to the welding current, and the tungsten electrode loss can be minimized while the weld brightness can be guaranteed. The AC ZERO-CROSSING current control function makes the low-current welding more stable, reduces the noise during high-current welding, and improves the reliability of the device. With a variety of protection functions, lack of phase protection, over voltage, under voltage, over current, overheating protection functions.
