is released.
5. When it is MMA or TIG Welding, You can ad-
just the welding current by turning this knob.
6. It is used for control MIG welding Voltage, so
the welding current can be adjusted.

OPERATION INSTRUCTIONS
PREPARING YOUR WORK AREA
1. You must have a sturdy work table that is
open below the area you are welding. Molten
slag will be blown through the work metal,
and must be able to fall away freely
2. Your work table must allow the work metal
to be firmly clamped to prevent it accidentally
falling or moving.
3. The floor and surrounding area of your work
site must not be flammable. A clean cement
floor is recommended. The welding process
will eject molten metal slag onto the floor,
and it will scatter for 8-10 feet or more in any
direction. Have an adequate fire extinguisher
available if needed.

CAUTION: Do not use an Argon/Mixed pres-
sure regulator/flow meter with CO

Shielding
gas. To use CO2 Shielding gas, you must install
a CO
2
Shielding gas pressure regulator/flow
meter.
1. Make sure the Flow Adjust on the Pressure
Regulator/Flow Meter is turned off. Then
Pressure Regulator/Flow Meter (not included)
firmly onto the cylinder valve.
2. Connect the gas air inlet (1) to your supply
CO
2,
Gas supply by one air hose (not supplied).
And remember to fasten it with coupling.
3. Adjust the flow rate of the gas by turning
the Flow Adjust. The typical flow rate is 10-30
CFH (cubic feet per hour). Make sure to check
the Welding Wire manufacturer’s recommend-
ed flow rate.
SETTING THE GUN POLARITY FOR WIRE TYPE
1. Set for Electrode Positive (GAS) for gas weld-
ing with solid-core wire and the gas supply is
needed.
NOTE: When it is gas welding, you also should
set common Wire feed rolls.
2. Set for Electrode Negative (DCEN) for gasless
flux core wire and this kind connect don’t need
gas supply.
NOTE: When it is gas-less welding, you also
should set the special Wire feed rolls.
