1. Power Indicator

The power indicator is illuminated when the correct mains power is applied to the power source and when the ON/

OFF switch located on the rear panel is in the ON position.

2. Thermal Overload Indicator (Fault Indicator)

This welding power source is protected by a self resetting thermostat. The indicator will illuminate if the duty

cycle of the power source has been exceeded. Should the thermal overload indicator illuminate the output of the

power source will be disabled. Once the power source cools down this light will go OFF and the over temperature

condition will automatically reset. Note that the mains power switch should remain in the on position such that

the fan continues to operate thus allowing the unit to cool sufficiently. Do not switch the unit OFF should a thermal

overload condition be present.

3. Digital Wirespeed/Amperage Meter (Left Digital Display)

MIG Mode

This digital meter is used to display the pre-set (preview) Wirefeed Speed in IPM (Inches per minute) in MIG mode

and actual welding amperage of the power source when welding. At times of non-welding, the digital meter will

display a pre-set (preview) value of Wirefeed Speed. This value can be adjusted by varying the Amperage Control

Knob (4).

STICK and LIFT TIG Modes

The digital meter is used to display the pre-set (preview) amperage in STICK / LIFT TIG modes and actual welding

amperage of the power source when welding. At times of non-welding, the amperage meter will display a pre-set

(preview) value in both STICK and LIFT TIG modes. This value can be adjusted by varying the Amperage Control

Knob (4).

When welding, this digital meter will display actual welding amperage in all modes.

At the completion of welding, the digital meter will hold the last recorded amperage value for a period of approxi-

mately 10 seconds in all modes. The amperage meter will hold the value until; (1) any of the front panel controls

are adjusted in which case the unit will revert to preview mode, (2) welding is recommenced, in which case actual

welding amperage will be displayed, or (3) a period of 10 seconds elapses following the completion of welding in

which case the unit will return to preview mode.

NOTE

The preview functionality provided on this power source is intended to act as a guide only. Some differ-

ences may be observed between preview values and actual welding values due to factors including the

mode of welding, differences in consumables/gas mixtures, individual welding techniques and the transfer

mode of the welding arc (ie dip versus spray transfer). Where exact settings are required (in the case of

procedural work), it is recommended that alternate measurement methods be utilized to ensure output

values are accurate.

3A Wirespeed Indicator

The Wirespeed Indicator illuminates when MIG mode is selected to identify that the Digital Wirespeed/Amperage

Meter is previewing Wirespeed in IPM (inches per minute).

The Wirespeed Indicator extinguishes when the user is MIG (GMAW/FCAW) welding or depressing the MIG gun

trigger and the Digital Wirespeed/Amperage Meter displays actual welding amperage of the power source.
