2.4 optIonal accessorIes
2.4.1 auto-fan KIt, p/n 16781
The Auto-Fan kit controls the operation of the cooling
fan. It will automatically turn the cooling fan on and off as
required. This serves to reduce overall shop noise and the
amount of air-bourne debris that is drawn into the unit.
2.4.2 Burn BacK MoDule,
p/n 0558008623.
This easy-to-install, plug-in module enables the use of
an adjustable Anti-Stick feature that allows adjustment
of burnback time to prevent wire sticking at the end of
a weld. See Sec 3.8 Installation and Sec. 4.2 Operation -
Process Setup.
For Spot Welding, Spotweld Nozzle, P/N 0885001602 is
recommended.
2.4.3 DIgItal Volt/aMMeter MoDule,
p/n 0558008585.
This easy-to-install digital meter kit alternately displays the
actual welding voltage and welding current every 4-sec-
onds. L.E.D.’s below the meter indicate which condition is
being displayed. After the torch trigger is released, the meter
will continue to flash for 20-seconds the last condition used
during welding. At the end of this time, the meter will reset
to zero. See Section 3.9 Installation.
2.4.4 Mt-250sg and st-23a spool gun
The Migmaster 275 unit is equipped with a built-in control
that accepts the MT-250SG or ST-23A spool gun. These
air cooled spool guns are designed for mig welding with
soft wires. They are completely portable up to 25-ft. and
weigh less than three (3) pounds. See 4.2.2 Installation/
Operation.
