SHIELDING GAS INSTALLATION
A compressed gas cylinder containing 75% Argon and 25% CO2 should be used when using the
MIG Welder (GMAW - GAS Metal Arc Welding). The fl ow regulator and supply hose is included with
your welder. Compressed gas can be obtained from your local welding supplier.
1.
Attach the compressed gas cylinder with a chain to
a wall or other secure object, to prevent the cylinder
from falling.
2.
After securing the tank, remove the cylinder cap if your
cylinder has one.
3.
Install the fl ow regulator to the supply valve on the cylinder
and tighten it with a wrench.
4.
Install one end of the gas supply hose into the outlet of
the fl ow regulator and tighten. Connect the other
end of the hose to the gas inlet located at the rear of
the MIG135 welding machine (The connector nipple
5/8-18 adapts to CGA-032). Ensure that the hose is
not twisted or knotted.
5.
Slowly turn on the gas cylinder valve. Open valve all the way.
6.
Depress gun trigger switch and adjust the fl ow regula-
tor to 25-30 cubic ft per hour (CFH), (12-14 l/min).
7.
Shut off the bottle valve when not in use. Power off
your unit when you are done welding.
8.
NOTE:
Always keep the valve of the gas cylinder
closed when it is not in use.
WELDING OPERATIONS
1.
Plug in the MIG135 Welding Machine.
2.
Straighten out the welding torch.
3.
Turn ON the unit and depress the gun trigger. Feed wire and cut 1⁄4” from the end of the nozzle.
4.
Remove any paint corrosion, grease and oils before welding. Place the ground clamp as close to the
welding zone as possible, and on a clean, bare surface.
