8. GAS PURGE/WIRE INCH –
located on the REDI-MIG Plus 4s Use the gas purge
®
momentary toggle switch to operate the gas solenoid to purge
air from the gas supply after connecting a new gas cylinder. Gas
purge will only operate while the toggle switch is held upwards.
Use the same toggle switch to operate the wire feed motor and
"cold" inch the wire, by pushing the toggle switch downwards.
9. 2 STEP/4 STEP TRIGGER OPERATION –
toggle switch located inside the wire feeder door of the
REDI-MIG 215 C and 255C. This provides two modes of
®
operation of the gun trigger. In 2 step mode, the gun trigger is
pressed to start welding and released to stop.
In the 4 step mode, pressing the gun trigger only operates the
gas solenoid, allowing shielding gas to flow. Releasing the gun
trigger activates the contactor which starts the wire feed motor
and connects welding current to the wire so that welding may
commence. To stop welding, the trigger must again be operated;
pressing it stops the wire feed, activates the burn back time
delay and opens the contactor after the pre-set burn back time.
Releasing the trigger stops the gas flow.
To recommence welding, the above cycle must be repeated.

11. CONTROL CABLE OUTPUT CONNECTION -
cable connects to the output connection plug on the front of the
REDI-MIG Plus 255S power source above the output terminals.
®
The control cable is used to connect the wire feeder to the
power source.
BURNBACK CONTROL –
feed bay. The burnback control adjusts the time period from
when the drive motor stops until the power source and gas
solenoid are switched off (approximately 0.1 seconds when fully
anti-clockwise to 1.1 seconds when adjusted fully clockwise).
The purpose of the burnback control is to prevent the electrode
wire sticking in the weld crater at the finish of the weld.
