SEctIoN 3
F. outPut cuRRENt/VoLtAgE coNtRoL - Sets the welding power output of the machine. When in the STICK, TIG,
and Touch TIG modes, this knob controls the output welding current (amperes). When in the MIG mode, this knob
controls the welding voltage (volts).
g. PRESEt SWItcH - When depressed, the digital meters will display the adjustment level of the OUTPUT CURRENT/
VOLTAGE control. This allows the welder the ability to quickly and easily preset the desired output level before at-
tempting to weld. This greatly reduces the "trial & error" approach to adjusting proper welding conditions.
H. DIgItAL AMPS DISPLAY - In the normal mode, this large, easy to read digital display indicates actual output amper-
age or preset amperage level when the PRESET SWITCH is depressed. Should a fault condition exist in normal opera-
tion, the display will show a code number. Refer to section 3.2.Q.
I. PoWER INDIcAtoR - Indicates power is present in the machine and that control circuits are energized.
J. DIgItAL VoLtS DISPLAY - In the normal mode, this large, easy to read digital display indicates actual output voltage
or preset voltage level when the PRESET SWITCH is depressed. Should a fault condition exist in normal operation, the
display will show "ERR". Refer to section 3.2.Q.
K. tEMP INDIcAtoR - Indicates that an over-temperature condition has occurred and the machine will cease to func-
tion. "ERR 4" will appear in the digital displays. The machine will return to normal operation once the temperature
decreases to a safe operating level.
L. FAuLt INDIcAtoR - Indicates an improper input line condition. The machine will not energize. The machine must
be reset by turning the POWER "ON/OFF" SWITCH to "OFF" and then back to "ON", after the proper input voltage is
selected.
a. Indicator illuminated - A primary input over-current condition has occurred.
b. Indicator blinking - The INPUT VOLTAGE SELECT SWITCH at the rear of the machine is set incorrectly for the pri-
mary input voltage applied.
M. PANEL / REMotE SWItcH - Selects the point of machine control.
1. PANEL position - Machine is controlled by the local front panel controls.
2. REMOTE position - Machine control is switched to the device plugged into the REMOTE RECEPTACLE.
N. REMotE REcEPtAcLE - For connecting remote output control devices such as hand pendant, foot / torch controls.
o. WIRE FEEDER REcEPtAcLE - For connecting ESAB 42 & 115 vac wire feeders.
P. outPut REcEPtAcLES - The secondary output welding terminals, POS (+) and NEG (-) are located in the lower left
of the front panel. See 2.5, 2.6, 2.7 for specific application.
Q. HELP coDES
ERR 1: High input voltage. Input voltage has exceeded requirement by 15% or greater.
ERR 2: Low input voltage. Input voltage is below requirement by 15% or greater. Note: Lower limit for 208 V supply is 5%.
ERR 3: Over-voltage at the output. If the output voltage exceeds 80V, the machine will shut off the contactor. This was
implemented to prevent a snubber failure from causing a dangerous voltage to appear at the output terminals.
ERR 4: Over temperature. One of the thermal switches has opened.
ERR 5: Over current in single-phase operation. In MIG welding, if an operator draws more than 250 amps for more than 5
seconds, this error will occur. In STICK or TIG modes, the machine will display this error if the control pot is turned
up above 250 amps in single phase.
ERR 6: Extended secondary short circuit. The machine will allow a full short circuit condition (secondary current of more
than 500 amps) to exist for 320 milliseconds before this error occurs.
ERR 7: Primary Over-current. This may indicate a failure of an output diode, the Hall Effect current sensor or a magnetic
short to chassis.
