Quick
Specs
Quick and easy maintenance with
single-side access to oil level check, oil
fill, oil filter, fuel filter and air cleaner.
Remote toolless oil drain allows oil to be
drained without getting under the engine
and reduces the chance of oil spillage.
Arc-Drive
™
makes welding easy.
Automatically enhances Stick welding,
especially on pipe, by focusing the
arc and preventing the electrode from
going out.
Big Blue

400 and 500
Diesel Engine-Driven
Welder/AC Generator
Issued June 2012 • Index No. ED/10.8
Hot Start
™
provides positive Stick
electrode starts making it easy to start
all types of electrodes and it also works
great for bead tie-ins.
Enclosed robust case design protects
internal components from impact and
allows air flow to cool and prolong the life
of the engine. Also reduces sound levels.
Engine gauges standard on all models
indicate engine oil pressure and coolant
temperature.
Designed for fleet owners that demand
the ultimate in reliability and performance.
Weatherproof Lexan
®
nameplate
resists cracking and fading, and is
color-coded for ease of operation.
GFCI receptacle as required on most
jobsites to protect operators from
electrical hazards.
CSA, IEC, and NEMA compliant for
welders. Degree of protection
provided by enclosure IP23.
Heavy-duty low-speed industrial
diesel engines are designed, built and
proven to operate over 10,000 hours
before the first basic overhaul.

Meter maintenance displays
• Fuel gauge
• Hour meter function
• Oil change interval
• High coolant temperature and low
oil pressure shutdowns
• Low fuel shutdown — engine shuts
down before system runs out of fuel,
making restarts easy.
