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.

INSTALLATION & OPERATION



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. 

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.
