diameter is selected. 

1.5.1.2Adjustment Mode Adjusting Button 

The  adjustment  modes  including  separate  adjustment  and  one-knob  intelligent  adjustment  are 

available. The former indicates that current and voltage are adjusted by two different knobs on the 

wire feeder controller; the latter indicates that the voltage automatically matches the given current, 

and can be finely tuned by a voltage knob. 

1.5.1.3Gas Check Button 

After you press this button, gas starts to be transmitted and lasts for 30 seconds, during which if 

you press the button again, gas transmission stops. 

1.5.1.4Welding Wire Check Button

button is released. 

This button has the same function as the inching button on the controller. 

1.5.1.5Solid Wire or Tubular Wire Selection Button 

1.5.1.6Working Mode Selection Button 

There are three working modes, including two-steps, four-steps, and spot welding. 

(1)

 

two-steps working mode: Turn on the switch on the welding torch to start welding, and turn 

off it to stop welding. This working mode is applicable to short seam welding. 

(2)

 

Four-steps working mode: Press the switch on the welding torch to start an arc, and release it 

to start welding. When you press the switch again, the  welding torch is under the control of 

arc stopping parameters set by the knob on the front panel, and when you release the switch, 

the welding torch stops working. This working mode is applicable to welding of long seams. 

(3)

 

Spot welding mode: An arc is started when you turn on the switch on the welding torch, and it 

automaticlly  stops when  the specififed period of spot welding  is expired.  If  you turn off the 

switch within the specified period, the arc is stopped. 

 

1.5.2Parameter Setting Area 

 

(1)

 

Rotary Knob of Arc Stopping Current or Spot Welding Period 

At the four-steps working mode, this rotary knob is used to adjust the arc stopping current. 

At  the  spot  welding  mode,  this  rotary  knob  is  used  to  adjust  the  period  of  spot  welding, 

ranging from 0.5 to 5 seconds. 

(2)

 

Rotary Knob of Arc Stopping Voltage 

At the four-steps working mode, this rotary knob is used to adjust the arc stopping voltage.
