10.7 Spot Welding Operation
Fit a spot welding nozzle to the MIG Torch for consistent spot welding operations. The Vikings
will operate effectively using 0.8mm (.030”) electrode wire when spot welding. Penetration depth
is limited when using 0.6mm (.024”) electrode wire for spot welding. Set the controls as follows
for spot welding:
a) Coarse & Fine Voltage Selector Switches and Wirespeed Control
Select higher Voltage Selector switch positions and set the Wirespeed Control between 354 to
590 ipm (9 to 15 metres/minute) 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.
11. ROUTINE MAINTENANCE & INSPECTION
The only routine maintenance required for the Viking is a thorough cleaning and inspection, with the
frequency depending on the usage and the operating environment.
WARNING 5
Disconnect the Viking 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 6
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 it from the mains supply voltage then open the
enclosure and use a vacuum cleaner to remove any accumulated dirt and 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 Viking should be carried out only by those who are familiar with
electrical equipment.
WARNING 6
Do not attempt to diagnose or repair unless you have had training in electronic measurement and
troubleshooting techniques.
