Controls and Settings
Fig 3
Welding Voltage.
This adjusts the welding voltage (weld power) from 0 to 10. Adjust knob
for power output required by job – range is 30 to 250 amps.
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
3.
MMA Amps.
This adjusts the MMA welding amperage (weld power) from 0 to 10. Adjust
knob for power output required by job – range is 15 to 200 amps.
4.
MIG / MMA switch
This switches between the machines two welding modes MIG / MMA
5.
OT LED. -
If this LED illuminates the 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.
6. Warning LED.
This warning light will come on under these situations to warn of either low
input voltage has been sensed or there is an internal fault with machine, check wiring
connections, if still illuminated contact R-Tech support department.
7. Power LED.
This lights when machine is switched on
8. Spool Gun Switch.
When if off position the internal wire feed motor is operational, when
switched to on, the internal wire feed motor is disabled and the spool on gun motor will be
operational – The speed of motors is controlled via the wire feed control knob 2.
(Ignore control knob on spool gun as this feature is only used on the MTS255 Digital
welder)
To fit spool on gun, connect the euro connector to euro socket on front of machine and the
separate 7 pin control plug into socket on front of machine.
