INSTALLATION

Electrical Shock
• 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 when connecting your welder's power cord directly to a properly grounded
230 VAC, 60 Hz, single phase, 50 amp input power supply. Or, when using the supplied
adapter, connect the 120V adapter to a properly grounded 120V, 20 amp input power supply.
1. POWER REQUIREMENT 230V - AC single phase 230V (200-240V) 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. This unit
is supplied with a NEMA Class 6-50P plug and will require a NEMA Class 6-50R receptacle.
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
they produce. This drop in voltage can affect the performance of the welder. If you need to use
an extension cord, it must be a size #12 or larger. Check with a qualified electrician and your
local electrical codes for your specific area. Do not use an extension cord over 25 ft. in length.
4. INSTALLATION OF OPTIONAL TIG TORCH
a. Remove the ground cable and the electrode holder from the weld output connections.
Install the ground cable to the Positive (+) weld output connection.
b. Secure the ground clamp to the work piece
c. Connect a regulator to a bottle of ARGON gas. Then connect the gas connection from
the TIG torch to the regulator.
d. Connect the TIG torch weld cable to the Negative (-) weld output connection.
e. Set desired amperage on the amperage control knob on the front panel of the welder.
f. Turn on the input power switch on the welder.
Be aware that the TIG torch will be electrically HOT when the Input Power Switch on the welder is
turned on.
g. Turn on the regulator on the bottle of shielding gas and adjust the regulator to
approximately 20 CFH. Then open the shielding gas valve on the torch to start the flow
of shielding gas.
