Specifications

7) MIG/TIG/STICK Process Selector
Each icon graphically represents each process. The top function represents MIG. The middle function
represents TIG. The bottom function represents Stick.
8) Voltage - When lit LED display will show welding voltage
9) Tig welding current / MIG Wire Speed Trim Adjustment Knob
For MIG Synergic operation, the amps are directly tied to the wire speed feed. Using this knob you can
fine tune the wire feed speed +/- from synergic setting. This is helpful as sometimes wire sizes can vary
slightly and this allows you to trim the feed speed to obtain the optimum weld bead.
For Mig ALT manual mode, this controls the wire feed speed.
For TIG operation this controls the welding amperage
10) Duty Cycle / Over current Warning
When the duty cycle has been exceeded or an over current condition will occur, the L.E.D. will light.
Allow the unit to cool while running until the light goes off or for 10 minutes before resetting the welder. If
the condition persists check for loose wires or voltage supply problems or call R-Tech support.
11) MIG Wave Form Control
Varies the slope of the current rise time during short circuit MIG operation. This affects the actual point
where the current has risen sufficiently to melt the wire.
12) Memory channel LED
13) CH (channel) / SAVE Process Selector
Pressing button will change memory store number and show values stored. To set up a new memory
store first select number to be programmed, then enter setup parameters as required and then press save
for 3 seconds to program current setting to shown memory number.
14) MIG /TIG post flow selector
Press to select post flow, this will be shown in LED (1) and can be adjusted with knob (16)
15) 2T/4T Torch Switch Selector
The torch trigger function is designed to operate for both MIG and TIG functions. To operate in 2T mode,
the trigger on either the MIG or TIG torch should be simply held down. The 4T function operates as a
torch “latch” in MIG mode that locks the MIG torch on without needing to hold the trigger.
To operate 4T in MIG mode, simply press the torch trigger and hold it down until the arc starts. To lock it
