8.6 Spot Welding Operation
Fit a spot welding nozzle to the MIG Torch for consistent spot welding operations. The Transmigs
will operate effectively using 0.8mm electrode wire when spot welding. Penetration depth is limited
when using 0.6mm electrode wire for spot welding. Set the controls as follows for spot welding:
a) Coarse & Fine Voltage Control Switches and Wirespeed Control
Select higher Voltage Control switch positions and set the Wirespeed Control between 9 to 15
m/min for maximum penetration.
b) Mode Selector Switch
Set the
MODE SELECTOR
switch to
SPOT.
c) Spot Time
Adjust the
SPOT TIME
control knob for the desired weld or 'ON' time for spot welding.
d) Dwell Time
The
DWELL TIME
control knob has no affect in this mode of operation.
9. ROUTINE
MAINTENANCE & INSPECTION
The only routine maintenance required for the Transmig is a thorough cleaning and inspection. For
operating environments with high levels of air born metallic dust particles clean out the Power
Source/Wirefeeder once a week. For operating environments with low levels of air born metallic dust
particles clean out the Power Source/Wirefeeder once every six months.
WARNING 7: Disconnect the Transmig from the Mains supply voltage before disassembling.
Special maintenance is not necessary for the control unit parts in the Power Source / Wirefeeder. If these
parts are damaged for any reason, replacement is recommended.
CAUTION 8: Do not blow air into the Power Source / Wirefeeder during cleaning. Blowing
air into the Power Source / Wirefeeder can cause metal particles to interfere with
sensitive electronic components and cause damage to the Power Source /
Wirefeeder.
To clean the Power Source / Wirefeeder, disconnect the Power Source from the Mains supply voltage,
remove the covers and use a vacuum cleaner to remove any accumulated dust. The Power Source /
Wirefeeder should also be wiped clean. If necessary, solvents that are recommended for cleaning electrical
apparatus may be used.
Troubleshooting and repairing the Transmig should be carried out only by those who are familiar with
electrical equipment.
WARNING 8: Do not attempt to diagnose or repair unless you have had training in electronic
measurement and troubleshooting techniques.
