R-Tech I-MIG160 MIG Operation Instructions Manual - Controls and Settings
Controls and Settings
Fig 3
1. 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 (Fig3.4)
2. Wire Speed This adjusts the wire feed speed from 0-100% Adjust the wire speed to suit
welding voltage (Fig3.1) and job requirements When adjusting the wire feed speed a
value is shown in the amperage LED (Fig3.5) This feature allows you to record this value
along with the preset welding voltage for easy setup to specific job when several different
welding jobs are being done
3. Arc Force Gives further adjustment on weld characteristics, on traditional transformer
machines this was known as choke. 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
4. Voltage LED Display This shows the preset welding voltage when no welding is being
carried out When welding this shows the actual welding voltage This allows the machine
to be calibrated to BS if required by your company
5. Amperage LED Display This shows the preset wire feed speed when no welding is being
carried out When welding this shows the actual welding amperage This allows the
machine to be calibrated to BS if required by your company. When the function is in
MMA, it shows the preset is welding amps.
6. Warning LED This warning light will come on under these situations:Duty cycle of
machine has been exceeded, the machine will stop working and the fan will continue to
run until machine has cooled down. The light will go off and welding may be carried out
again. If duty cycle has not been exceeded the warning light comes on to warn of either
low input voltage has been sensed or there is an internal fault with machine
7. Power LED This lights when machine is switched on
8. Switch MIG/MMA.
