Large analog volt and ammeters for
easy viewing.
Solid-state weld contactor provides
longevity to match the ultra-durable
and reliable reputation of the Delta-Fab.
Large output voltage range provides
more flexibility on a variety of wire
diameters. Also aids operator with
voltage losses that occur when operating
long distances from power source.
115 VAC duplex receptacle provides
15 amps of auxiliary power.
Four-Drive-Roll feeding system with
independent tension control handles
small and large diameter wires. (Drive
rolls and guides ordered separately.)
Remote voltage control is standard.
Parameter adjustments can be made
in weld cell or at a remote location.
Run-in standard on 24A for better
arc-starting performance on a variety
of wires.
14-pin select is easy to set up with
no external switches to put in the
wrong position.
14-pin receptacle provides quick,
direct connection to wire feeders and
accessories.
The Power of Blue® .
Welder is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
See option and package
descriptions on page 3.
NEW!MIGPower Source Solutions
Line voltage compensation keeps
welding parameters constant even
when input voltages change ±10%.
Eliminates need to change welding
parameters throughout the day.
Material specific output studs
provide the flexibility to produce the
optimal arc characteristics for
aluminum, stainless steel and all
other materials.
Thermal overload protection
automatically shuts down the system
to prevent high repair costs.
Auto Remote Sense™automatically
selects remote control requirements
through the 14-pin receptacle.
Eliminates switches and confusion
for the operator.
