Power(2A)

Power fuse. The fuse is broken for protecting control transformer while

control electric circuit is short.

8

Voltage indicator

For output voltage adjust while welding

9

Current indicator

For welding current/output current adjust

10

Control

Indicate welding machine if is on or off

11

O.C

Abnormity indicator. If the indicator lights, the inner circuit is abnormal and

machine stops working.

12

Crater Arc

(ON/OFF)

Crater arc selection.

For CO2 welding while it is on

“arc off”

position, press the torch switch

for welding and loosen torch switch for welding stop, and this model is

suitable for short-time welding.

For GMAW welding while it is on

“arc on”

position, press the torch switch

and after arc ignition can loosen the torch switch, the normal welding can be

continued. Press the torch switch again, the arc will be reduced into a less

value which is set by adjusting the knob on front panel, and the weld will be

stop if you loosen the torch switch now. It is suitable for long-time welding.

13

MMA/CO2

Function switch,to chose working condition

14

Gas test/Weld

Gas test/weld selection. On “gas test” position can check the flux of CO2 or

argon; on “weld” position the machine works normally.
