Controls and Settings

1. Spot Welding
This adjusts the amount of time the weld will last. When you press the torch switch the
machine will do a single spot weld according to the time you have set and then stop, then
release torch switch. Press torch switch again to do another spot weld.
2. Arc Force
Gives further adjustment on weld characteristics, on traditional transformer machines this was
known as choke. Low setting is ideal for automotive work.
Lower setting = softer weld with less splatter and less penetration – for thinner materials
Higher setting = harsher weld with more splatter and penetration – for thicker materials
3. Welding Voltage
This adjusts the welding voltage (weld power) from 0 to 10. Adjust knob for power output
required by job, preset welding voltage is shown in LED (Fig 3.7)
4. Stitch Welding
This is used in combination with the spot welding control. This sets the interval time between
spot welds.
When you press the torch switch the machine will do a spot weld as set by the spot welding
control knob (Fig 3.1) and then a delay time set on stitch welding knob and then another spot
weld is carried out. To stop stitch welding release the torch trigger.
