2T MODE
The trigger is pulled and held on to activate the welding circuit, when the trigger is released, the
welding circuit stops. This function without the adjustment of start current and crater current is suitable
for the Re-tack welding, transient welding, thin plate welding and so on.

Introduction:
(1) 0: Press the gun switch and hold it. Electromagnetic gas valve is turned on. The
shielding gas stars to flow.
(2) 0
～
t1: Pre-gas time (0.1~2.0s)
(3) t1
～
t2: Arc is ignited and the output current rises to the setting welding current (I
w
or
I
b
) from the min welding current.
(4) 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;
(5) t3: Release the gun switch, the welding current will drop in accordance with the
selected down-slope time.
(6) t3
～
t4: The current drops to the minimum welding current from the setting current (I
w
or I
b
), and then arc is turned off.
(7) t4
～
t5: Post-gas time, after the arc is turned off. You can adjust it (0.0~10s) through
turnning the knob on the front panel.
(8) t5: Electromagnetic gas valve turned off, the shield gas stops to flow, and welding is
finished.
4T Mode
This is known as ’latching’ mode. The trigger is pulled once and released to activate the
Introduction
1. 0:
Press the gun switch and hold it. Electromagnetic gas valve is turned on. The shielding gas stars to
flow.
2. 0~t1:
Pre-gas time (0.1~2.0s)
3. t1~t2:
Arc is ignited and the output current rises to the setting welding current (Iw or Ib) from the
min welding current.
4. 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.
5. t3:
Release the gun switch, the welding current will drop in accordance with the selected down-slope
time.
6. t3~t4:
The current drops to the minimum welding current from the setting current (Iw or Ib), and
then arc is turned off.
7. t4~t5:
Post-gas time, after the arc is turned off. You can adjust it (0.0~10s) through turnning the knob
on the front panel.
8. t5:
Electromagnetic gas valve turned off, the shield gas stops to flow, and welding is finished.
