Section 2 - OPERATING INSTRUCTIONS
7. Spool Gun Connection -
Connection for the optional spool
gun on the 215C and 255C.
8. GAS PURGE/WIRE INCH –
A two position toggle switch
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 –
A two position
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.
10. Output Terminals –
Dinse connection used to connect
electrode cable and work return lead.
FOR OUT POLARITY CONNECTION REFER TO SECTION 1.5
11. CONTROL CABLE OUTPUT CONNECTION -
The control
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 –
This control is located in the wire
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.
