0: Press the gun switch and hold it. Electromagnetic gas valve is turned on. The shielding gas stars to
flow.
0
～
t1: Pre-gas time (0~2s)
t1
～
t2: Arc is ignited and the output current rises to the setting welding current (Iw or Ib) from the
min welding current.
t2
～
t3: During the whole welding process, the gun switch is pressed and held without releasing.
Note: Select the pulsed output, the base current and welding current will be outputted alternately;
otherwise, output the setting value of welding current;
t3: Release the gun switch, the welding current will drop in accordance with the selected down-slope
time.
t3
～
t4: The current drops to the minimum welding current from the setting current (Iw or Ib), and
then arc is turned off.

t5: Post-gas time, after the arc is turned off. You can adjust it (0~10s) through turnning the knob
on the front panel.
t5: electromagnetic gas valve turned off, the shield gas stops to flow, and welding is finished.
Short circuit protect function
：
○
1 TIG /DC/LIFT
：
If the tungesten electrode touches the workpiece when welding, the current will drop to
20A, which can reduce the tungsten spoilage farthestly
，
prolong the using life of the tungsten electrode
，
and prevent tungsten clipping.
○
2 TIG /DC/HF
：
If the tungesten electrode touches the workpiece when welding, the current will drop to 0
