CHECK THE GAS FLOW
WARNING
IMPROPER HANDLING AND
MAINTENANCE OF COMPRESSED
GAS CYLINDERS AND REGULATORS
CAN RESULT IN SERIOUS 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 compressed gas
cylinder adapter 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.
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 flow. KEEP THE
TRIGGER PULLED. Listen and feel
for gas flowing from the end of the
welding gun. If your regulator has
no adjustment, it has been pre-set
at the factory for a flow of 20 cubic
feet per hour. If your gas regulator
has an adjustment to control the
gas flow rate, turn the adjustment
key clockwise to increase gas flow;
counterclockwise to reduce flow.
For most welding, the gas flow
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 windbreak to keep the
shielding gas from being blown
from the weld area.
• MAKE SURE TO TURN OFF
THE GAS CYLINDER VALVE
WHEN DONE WELDING.
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. Change to a neoprene
drive roller when welding with
aluminum wire.
STANDARD DRIVE ROLLER
Change the standard drive roller
according to the following steps:
1. Remove the drive tension by
unscrewing the tension adjusting
screw (ALL THE WAY in a counter-
clockwise direction). The drive
tension screw will come loose,
allowing you to pull the drive
tension arm up away from the drive
roller. Make sure to keep the screw
and the spring in place with the
drive tension arm.
2.
3.
If there is wire already installed in
the welder, roll it back onto the wire
spool by hand-turning the spool
counter-clockwise. Be careful not
to allow the wire to come out of the
rear end of the gun without holding
onto it or it will unspool itself. Put
the end of the wire into the hole on
the outside edge of the wire spool
and bend it over to hold the wire in
place. Remove the spool of wire
from the welder.
Loosen the drive roller setscrew
and pull the drive roller off the drive
shaft.
