Issued August 2007 • Index No. DC/12.7
Built-in 10-pin
connector for
direct hookup of
Spoolmatic
®
15A
or 30A spool guns.
Large, dual digital
meters enable the
operator to preset
weld voltage in CV
mode and amperage
in the CC mode (DX
model only) before
striking an arc.
Arc control adjusts
inductance to optimize
MIG arc performance.
Line voltage
compen sation keeps
output power constant
even if input power
varies ±10%.
Built-in 14-pin
connector provides
quick, direct con -
nection for 14-pin
24 VAC Miller wire
feeders and
accessories.
Fan-On-Demand

Shopmate 300 DX
Single-phase MIG or
DC multi process
capability for versatility
with outstanding arc
performance in CV
mode (MIG) and CC
