ENGINE OPERATION
Operate the welder with the doors closed. Leaving the doors
open changes the designed air flow and can cause overheating.
STARTING THE SA-400I
®
PERKINS 404D-22
DIESEL ENGINE
1.
Turn the “IDLER” switch to “HIGH”.
2.
Turn the “IGNITION” switch to “ON”.
3.
Press the Glow Plug button for 20 to 30 seconds.
(maximum 60 seconds).
4.
Press the Start button. When the engine starts running,
release both buttons. If the engine fails to start in 20
seconds, wait 30 seconds and repeat the above
procedure.
5.
Observe the oil pressure. If no pressure shows within
30 seconds, stop the engine and consult the engine
operating manual. To stop the engine, turn the
“IGNITION” switch to “OFF”.
6.
If the engine protection warning light comes on during
cranking or after start up, the “IGNITION” switch must
be turned “OFF” to reset the engine protection system.
7.
Allow the engine to run at high idle speed for several
minutes to warm the engine. Stop the engine and
recheck the oil level, after allowing sufficient time for
the oil to drain into the pan. If the level is down, fill it to
the full mark again. The engine controls were properly
set at the factory and should require no adjusting when
received.
Do not attempt to use this equipment until you have thor-
oughly read the engine manufacturer’s manual supplied
with your welder. It includes important safety precautions,
detailed engine starting, operating and maintenance
instructions, and parts lists.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or elec-
trode with skin or wet clothing.
• Insulate yourself from work and ground
• Always wear dry insulating gloves.
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or vent
exhaust outside.
MOVING PARTS can injure.
• Do not operate with doors open or guards off.
• Stop engine before servicing.
• Keep away from moving parts.
See additional warning information at
the front of this operator’s manual.
COLD WEATHER STARTING:
With a fully charged battery and the proper weight oil, the engine
should start satisfactorily even down to about -15°F (-26°C), it
maybe desirable to install cold-starting aides.
Note: Extreme cold weather starting may require longer glow
plug operation.
Under NO conditions should ether or other starting fluids
be used!
HIGH ALTITUDE OPERATION:
The engine will run correctly up to an altitude of 600 meters
(12,000 ft.). If the engine is to be operated permanently at an
altitude above this, the fuel consumption and exhaust emissions
may be excessive.
Contact a Perkins Service Representative for any engine
adjustments that may be required.
STOPPING THE ENGINE
1. Turn the “IGNITION” switch to “OFF”
At the end of each day’s welding, check the crankcase oil level,
drain accumulated dirt and water from the water separator
located on the fuel rail. Refill the fuel tank to minimize moisture
condensation in the tank. Also, running out of fuel tends to draw
dirt into the fuel system.
When hauling the welder between job sites, close the fuel feed
valve on the separator located on the fuel rail.
If the fuel supply is cut off or runs out while the fuel pump is
operating, air may be entrapped in the fuel distribution system. If
this happens, bleeding of the fuel system may be necessary. Use
qualified personnel to do this per the instructions in the
MAINTENANCE section of this manual.
