OTHER FEATURES

•Perkins 4-cylinder, water cooled diesel engine. Designed for long life, easy maintenance and excel- lent fuel economy.

•Engine protection system shuts the engine down for low engine oil pressure or high coolant temperature.

•Electronic Engine Idler. Engine automatically goes to low idle in 10 to 14 seconds after welding or use of auxiliary power stops. Includes high idle switch.

•Gauges for engine oil pressure, coolant temperature and battery charging ammeter.

•Engine hour meter standard.

•Extended range 22.5 gallon (85.1 L) fuel tank.

DUTY CYCLE

Duty cycle is based on a ten minute period and opera- tion in an ambient temperature of 104°F(40°C).

The SAE-400 SEVERE DUTY IS NEMA rated at 60% duty cycle. Duty cycle is based on a ten minute period. Therefore, a 60% duty cycle welder can be operated at nameplate rated output for 6 minutes out of every 10 minute period without overheating.

The auxiliary power can be used continuously (100% duty cycle) within its rated current capacities.
