(S) Short contact tips are recommended for proper wire stick out for flux cored wire welding.
(M) Medium contact tips are recommended for proper wire stick out in spray transfer Mig
welding.
(L) Long contact tips are recommended for good visibility and proper wire stick in dip transfer
Mig welding.
* Requires support liner for .023" wire. Order P/N 999797.

2.4.2 DIGITAL VOLT/AMMETER MODULE, P/N 32857.
This easy-to-install, plug-in module mounts in place of
the top blank cover plate of the upper-right front panel
location in the 250 unit. This unique meter module
alternately displays welding voltage and current (of the
dial-set welding condition) every 4-seconds. Two L.E.D.’s
labeled Amps and Volts provided below the meter win-
dows, alternately illuminate to indicate which condition is
being displayed. The voltage indication is displayed in
1/10-volt increments (e.g.: 20.5), while the current indi-
cation is usually displayed in three-whole digits (e.g.:
225).
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. For installation see Section 3.10.
2.4.3 ST-23A SPOOL-ON-GUN TORCH, P/N 19164
(see F-14-353).
The Migmaster 250 unit is equipped with a built-in control
for the ST-23A Spool-On-Gun welding torch. The ST-
23A is a high performance, 250 ampere continuous duty
spool-on-gun torch designed for the mig welding pro-
cess. It is completely portable (up to 30-ft.), air-cooled
and hand operated, and weighs less than three (3)
pounds. The gun is equipped with (30) foot lines. For
installation and operation, see Section 4.2.2.
