Do not remove grounding prong or alter the plug in any way. Use only the supplied adapter
between the welder's power cord and the power source receptacle. Make sure the POWER switch
is OFF then connect your welder's power cord to a properly grounded 120 VAC (110V-130V), 60
Hz, single phase, 20-amp power source.
1. POWER REQUIREMENT 120V - AC single phase 120V (110-130V) 50/60 HZ fused with a 20-
amp time delayed fuse or circuit breaker is required. DO NOT OPERATE THIS UNIT if the
ACTUAL power source voltage is less than 110 volts AC or greater than 130 volts AC.
2. EXTENSION CORD - We do not recommend an extension cord because of the voltage drop
produced. This drop in voltage can affect the performance of the welder. If you need to use an
extension cord, check with a qualified electrician and your local electrical codes for your specific
3. INSTALL THE WIRE ROLLER - The wire roller has been factory installed. However, check to make
certain the correct wire groove is in place to accommodate the size of wire you are using. Open the
wire feed compartment. Adjust the drive roller according to the following steps, see the following
images regarding the wire feeder structure (figure 2).
a. Open the door to the welder drive compartment.
b. Remove the drive tension by loosening the drive tension adjusting knob (1) and lifting the
Drive Tension Adjustor away from the Drive Tension Arm (2). Lift the Drive Tension Arm
away from the Drive Roller (3).
c. If there is wire already installed in the welder, roll it back onto the wire spool by hand-
turning the spool clockwise. Be careful not to let all of the wire come out of the rear end of
the inlet guide tube without holding onto it or the wire spool 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 drive compartment of the welder.
d. Rotate the Drive Roller Cap (3) counter-clockwise and remove it from the Drive Roller.
e. Pull the Drive Roller off the Drive Roller shaft.
Based on the wire diameter, select the correct groove. When installing the drive roller, the
number stamped on the drive roller for the wire size you are using should be facing you.
Push the Drive Roller onto the Drive Roller Shaft.
g. Reinstall the Drive Roller Cap and lock in place by turning it clockwise.
h. Close the door to the welder drive compartment.
