that is versatile and easy to use. It is equipped
with many outstanding features.
Welds 22 gauge up to 1/2 in. (13 mm) thick steel.
Excellent aluminum welding with optional
Hobart Spool Gun 3545-20.
Seven-tap voltage control allows for a smooth,
easy-to-control arc.
Infinite wire feed speed control for precise
adjustment of penetration and weld bead shape.
Comes complete with 250 amp gun and built-in
running gear/cylinder rack.
Handles wire spools up to 45 lb. — wire feed
speed adjusts from 90 to 750 IPM.
Built-in thermal overload protects the unit.
Reversible drive rolls: two grooves for three wire
sizes on one drive roll. Decreases spare parts and
changeover time.
Hinged door for easy access to wire drive system
for spool and drive roll changes.
FEATURES BENEFITS
Makes controls easy to see and access.
Excellent short arc performance with easy to control weld puddle.
Increases machine output for higher productivity.
Higher machine output duty cycle, increasing productivity with longer welding periods. Versatile for MIG and
Flux Cored, gas or gasless welding applications. Can weld at higher amps at lower duty cycle.
Simplified and accurate adjustments. Maximizes amount of control. Allows for smooth arc with high operator appeal.
Excellent for pushing soft aluminum wires.
50% less stocking of drive rolls. Standard, one-piece drive roll decreases spare parts and changeover time,
reducing overall costs.
For greater accessibility to wire feeder panel for spool and feed roll changes, increasing productivity and operator appeal.
Allows for precise adjustment of penetration and weld bead shape.
Amperage draw of 35 amps at rated load of 230 V input saves energy.
Ready to set up and weld: comes complete with wire feeder, running gear, cylinder rack, regulator/flow gauge,
MIG gun, cable and clamp, extra tips.
Five-year warranty on transformers, stabilizers and generators; three years on electronics (drive motors, rectifiers);
and one year on guns (MIG and plasma torches).
