PANEL FUNCTION INSTRUCTION
1. Change-over switch
1
）
Crater On/Off switch: When in the "Off" position, press the welding gun switch, the welding machine starts
working. Now that the welding machine is in the welding state, adjust the output voltage and output current by
rotating the welding voltage and welding current turn-knob on the wire feeder. Loose the welding gun switch, the
welding machine stops.
When in the "On" position, press and loose the welding gun switch for the first time so that the welding machine
is in the welding state. Adjust the output voltage and output current by rotating the welding voltage and welding
current turn-knob on the wire feeder. Press the welding gun switch again and the welding machine is in the crater
state. Adjust the output voltage and output current by rotating the crater voltage and crater current turn-knob on
the panel. Loose the welding gun switch once again, the welding machine stops.
2
）
Flux-cored/Solid core conversion function: When the switch is in the solid core position, CO
2
gas welding wire is
used. When the switch is in the flux-cored position, self-shielded welding wire is applied.
3
）
Gas purge switch: When this switch is in the gas examining position, the gas supply of the welding machine is
examined. When this switch is in the welding position, the welding machine is in the normal welding state.
4
）
Welding wire diameter switch: When welding wires of different diameter are used, the switch shall be in the
corresponding position correctly.
2. Adjusting knob
1
）
Crater voltage adjustment: This knob is inoperative at "Off" state. At "On" state, this knob is used to adjust arc
starting voltage and crater voltage.
2
）
Crater current adjustment: This knob is inoperative at "Off" state. At "On" state, this knob is used to adjust arc
starting current and crater current.
3
）
Arc trait adjustment: The softness and hardness level of the electric arc can be adjusted to achieve best welding
effect. When the current is small, the arc shall be hard to reduce arc interruption. When large current, the electric
arc shall be soft so as to reduce splatter.
