- Features
■ The pulse TIG welder can start arc with HF Pulse, adopt DSP digital control, and have 30 saving channels
■ Automatic switch off from overcurrent, overheat, over/under voltage
■ Support DC TIG welding, pulse TIG welding and MMA welding, can weld such metals as stainless steel, alloy steel, copper, silver, titanium, etc.
■ LCD shows menu and functions, with fast forward key on the front panel
■ Pre digital set of welding current, current up/down slope
■ Arc burns stably even the lowest output current is 10A, even 5A
