3-phase, 4-pole revolving field
technology

provides efficient welding

current with less horsepower than DC
generator technology — less horsepower
per welding amp saves fuel — as much
as 20 to 30 percent. Easily connects in
parallel with no special kits for heavy
gouging or stud welding applications.

Five welding ranges

provide

overlapping ranges and fine current
control in each range for easy set-up
and control of welding amperage.

The F3L2011, 3-cylinder

Deutz diesel

engine

provides 30 HP at 1850 RPM.

Single side service. Direct fuel injection
for fuel economy and easy starts. Air/oil
double-cooled diesel for maximum
reliability in all environments.

Compact and lightweight

, this low-

speed diesel measures in at 625 x
927 x 1422 mm (24-5/8 x 36-1/2 x
56 in).

Remote control facility

allows

precise adjustment of amperage
without walking back to the machine.

3 kW/kVA auxiliary power

while

welding is available from one
120 VAC duplex receptacle and one
240 VAC duplex receptacle that are
circuit breaker protected.

Note: Parts and labor warranted for three years.

Engine warranted by Deutz for three years.

Rugged controls

with no printed

circuit boards.
