Note!
When starting arc, the short-circuit time exceeds 2s, the welder turns off the
output current, and it is necessary to lift the welding torch and short-circuit the
tungsten electrode and workpiece again before starting arc again.
Note!
In the welding process, if there is short circuit between tungsten electrode and
workpiece, the welder will immediately reduce the output current; if the short circuit
time exceeds 1s, the welder will turn off the output current, and the welding torch
needs to be lifted to start the arc again.
