Site Selection

Select a clean, dry location with adequate working space around all components. Provide at least two
feet of space in front of and behind the unit to allow for free flow of air.

Power Source Connection

Power Requirements
This welder is designed to operate on a properly grounded 230V OR120V, 60HZ, single-phase
alternating current (AC) power source fused with a 50A or 20A time delayed fuse or circuit breaker.
It is recommended that a qualified electrician verify the actual voltage at the receptacle into which the
welder will be plugged and confirm that the receptacle is properly fused and grounded. The use of the
proper circuit size can eliminate nuisance circuit breaker tripping when welding.
Do not operate this welder if the actual power source voltage is less than 105 VAC. Contact a qualified
electrician if this problem exists. Improper performance and/or damage to the welder will result if
operated on inadequate or excessive power.
Stick Welding Set Up
Determine the polarity configuration needed based on the electrode's polarity requirements. NOTE:
Most electrodes will require DCEP (Direct Current Electrode Positive) setup. For this configuration,
connect the electrode cable to the positive terminal and the ground cable to the negative terminal. For
DCEN (Direct Current Electrode Negative) setup, connect the electrode cable to the negative terminal
and the ground cable to the positive terminal. Once the cables are connected, select Stick welding with
the selector on the fron panel.
TIG Welding Set Up
Because this machine is not equipped with a built-in gas solenoid, a TIG torch with valve is needed.
DCEN configuration is required for TIG welding. Connect the torch cable to the negative terminal and
the ground cable to the positive terminal. Connect the gas hose from the torch to the Argon regulator on
the cylinder. Once the cables are connected, select TIG welding with the selector on the front panel.
