⚠WARNING
ELECTRIC SHOCK CAN KILL!
High voltage danger from power source! Consult a qualified electrician for proper installation of
receptacle. This welder must be grounded while in use to protect the operator from electrical
shock.
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 230 VAC (220V - 240V), 60
HZ, single phase, 50 amp power source. If operating on 120V, attach the 120V Adapter cord to
the unit power cord and then connect the assembly to a properly grounded 120 VAC (110V-130V),
60 Hz, single phase, 20 amp power source.
1. POWER REQUIREMENT 230V - AC single phase 230V (220-240V) 50/60 HZ fused with a 50
amp time delayed fuse or circuit breaker is required. DO NOT OPERATE THIS UNIT if the
ACTUAL power source voltage is less than 215 volts AC or greater than 240 volts AC.
2. 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.
a. When connecting this unit to 120V power, connect the 120V adapter cord to the
power cord pigtail that is attached to the machine.
3. 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 area.
4. 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 Figure 2 about the wire feeder structure:
