IMPROPER HANDLING AND MAINTE-
NANCE OF COMPRESSED GAS CYLIN-
DERS AND REGULATORS CAN RESULT IN
SERIOUS INJURY OR DEATH! Always
secure gas cylinders to the welding cart, a
wall, or other xed support to prevent the
cylinder from falling over and rupturing.
Read, understand, and follow all the COM-
PRESSED GASSES AND EQUIPMENT HAZ-
ARDS in the SAFETY SUMMARY at the front
of this manual. Secure your gas cylinder to
the welding cart, or other xed support.
1. Remove the protective cap from the cylinder
and inspect the regulator connecting
threads for dust, dirt, oil, and grease.
Remove any dust or dirt with a clean cloth.
DO NOT ATTACH YOUR REGULATOR IF
OIL, GREASE, OR DAMAGE ARE PRESENT.
2. Open the cylinder valve FOR JUST AN
INSTANT to blow out any foreign matter
inside the valve port. Never aim the open
valve cylinder port at yourself or bystanders.
3. Screw the regulator
into the cylinder valve
and tighten with a wrench.
4. Firmly push the gas hose over barbed t-
tings on back of welder and regulator.
5. Secure both ends of hose onto barbed t-
tings with hose clamps.

IMPROPER HANDLING AND MAINTE-
NANCE OF COMPRESSED GAS CYLINDERS
AND REGULATORS CAN RESULT IN SERI-
OUS INJURY OR DEATH. To reduce the risk of
injury or death, always stand to the side of the
cylinder opposite the regulator when opening
the cylinder valve, keeping the cylinder valve
between you and the regulator. Never aim the
open cylinder valve port at yourself or
bystanders. Failure to comply with this warning
could result in serious personal injury.
Note: If the cylinder you have is equipped with
male regulator connecting threads instead of
female, you will need to obtain a special com-
pressed gas cylinder adaptor from your gas
supplier to install between your gas cylinder
and regulator.
-The gas control function does
not require
the welder to be turned on or plugged in.
-To avoid damage to your regulator, make
sure you have the regulator valve closed
before opening the cylinder valve.
1. Slowly crack open the cylinder valve, then
turn open ALL THE WAY.
2. Pull the trigger on the gun to allow the gas to
ow. KEEP THE TRIGGER PULLED. Listen and
feel forgas owing from the endof the weld-
ing gun. If your regulator has no adjustment,
it has been preset at the factory for a ow of
20 cubic feet per hour. If your gas regulator
has an adjustment to control the gas ow
rate, turn the adjustment key clockwise to
increase gas ow; counterclockwise to
reduce ow. For most welding, the gas ow
should be set at 15-20 cubic feet per hour. If
no gas is heard or felt, verify all steps
involved in connecting the gas.
3. Release the trigger.
Note: If welding outside or in a draft, it may
become necessary to set up a wind break to
keep the shielding gas
from being blown from
the weld area.
- MAKE SURE TO TURN OFF THE GAS
CYLINDER VALVE WHEN DONE WELD-
ING.
ALIGN AND SET THE DRIVE ROLLER
Before installing any welding wire into the unit,
the proper sized groove must be placed into
position on the wire drive mechanism.
