The Power of Blue®.

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.

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

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.

Rugged controls with no printed circuit boards.

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.

Compact and lightweight, this lowspeed diesel measures in at 625 x 927 x 1422 mm (24-5/8 x 36-1/2 x 56 in).

Note: Parts and labor warranted for three years. Engine warranted by Deutz for three years.
