WIRE CHECK: Press Wire check push button to check the motor rotation
and for feeding wire in torch when you change an empty wire roll with
new one.
WIRE SPEED: This is knob to set a wire feed speed according to welding
volts and for control of welding current, To run motor fast or want to
increase in welding current rotate it clock wise and vice-versa. The
rotating device below knob is called potentio meter.
GAS PLUG: Connect the torch gas pipe here. When gas check or torch
trigger is pressed the gas comes from this plug and passes to welding
end of torch.
TORCH PLUG: This is base plug for the plug that is attached with torch,

Mig wire and welding current runs through this connector.
VOLT METER: By pressing OCV CHECK switch in front of power source, It
shows the open circuit volts of power source and when you do the
welding it shows welding volts.
AMPERE METER: It shows welding current during welding.
OCV CHECK: Press this toggle to check the set value of OCV(open
circuit volts).
POWER ON: Power on toggle switch. It is used for switching power source
