Installation - Klutch ST80i Owner's Manual

Power Light
The Power Indicator Light is on when the machine is turned on.
Thermal Protection Indicator Light
When the thermal overload indicator is on, it indicates the machine has exceeded the allowable
internal temperature. The machine automatically turns off welding output but the fan will remain on
to cool down the internal components. When the internal temperature had decreased, the machine
will automatically turn welding output back on.
Current Adjustment
Current adjustment is on the front panel of the machine. It has infinite current output adjustment
from 20 to 75 Amps.
Positive Output Connector
This is the connector for the electrode holder and cable, most often, when STICK welding. When
this machine is used for TIG welding, this connector is for the grounding cable.
Negative Output Connector
This is the connector for the ground cable and clamp, most often, when STICK welding. When this
machine is used for TIG welding, this connector is for the TIG torch.
Ground Cable and Clamp
The ground cable and clamp are attached to the work piece to complete the circuit allowing the flow
of current needed to weld.
Welding Cable and Electrode Holder
One end of the cable is connected to the output connectors of the welder. The electrode is held in
the electrode holder for welding.
Power Cord
The power cord connects the welder to the 120V volt power supply. Plug the 15 amp plug into a
115V/20Amp receptacle to supply power to the welder.

INSTALLATION

1. POWER REQUIREMENT - AC single phase 120V (110-120V), 60 HZ with a 20 amp circuit
breaker is required. DO NOT OPERATE THIS UNIT if the ACTUAL power source voltage is less
than 105 volts AC or greater than 132 volts AC.

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. Do not use any adapters
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 to a properly
grounded 120 VAC, 60 HZ, Single Phase, 20 Amp input power supply.
