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.
ASSEMBLY
GROUNDING
Attach a ground wire to the screw on the
lower right of the back of the welder. Connect
the other end of the wire to an appropriate
ground, such as a steel workbench, steel biding
member or grounding electrode.
ATTACH AIR SUPPLY
CAUTION: Do not use an Argon/Mixed pres-
sure regulator/flow meter with CO
2
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 (7a) to your
supply CO
2,
Gas sup-
ply 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.
ASSEMBLY THE WIRE FEEDER
NOTE: When installing wire of a different size
or composition, you will also need to change
wire settings, set the gun polarity, and, pos-
sibly, install a gas cylinder, Refer to the below:
