Who used the controller to change argon arc welding into cold welding?

1: You can change it first. Taobao sells modified ones, and a few hundred dollars is enough.

2. The modified machine can't be called cold welding machine, but a simple pulse welder.

3. The real cold welding machine has a millisecond-level extremely fast discharge speed, a special energy storage capacitor and a microcomputer chip, which is not available in argon arc welding. It's cold welding machine's secret to discharge quickly with high current. At present, the best technology in China is HS-ADS02. Search for it yourself.
