FABRICATOR 211i INSTALLATION/SETUP
INSTALLATION/SETUP 3-10 Manual 0-5157
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.
