7-2. Air Compressor Gauge And Regulator

Ref. 804 857-A / Ref. 229 219-A / 229 807-B

The air pressure gauge reads the air

compressor line pressure. Air pres-

sure in the compressor case may be

high even when the gauge reads

zero. Wait 10 minutes for compres-

sor blow down cycle to complete be-

fore checking/adding oil or perform-

ing maintenance.

Weld output and generator power are
reduced when the air compressor is

on.

With the compressor on, weld or gen-

erator loads will cause the engine to

run at 3600 RPM.

Air Compressor Gauge

Air Pressure Regulator

Adjust system pressure with the regulator.

Set pressure in the no-flow condition only.

To reduce engine load and allow higher

weld and generator output, set at lowest

possible pressure for the job.

Set pressure in the 80

−

100 psi (552

−

689 kPa) range to operate plasma cut-

ting equipment or to gouge (CAC-A).

Set pressure in the 100

−

125 psi (689

−

862 kPa) range to operate pneumatic

tools.

Do not set pressure above 150 psi
(1034 kPa). If air pressure exceeds

150 psi the compressor clutch will dis-

engage and shut down the compres-

sor.

Do not set pressure below 80 psi (552

kPa). Compressor will supply 80 psi re-

gardless of setting below 80 psi.

See Section 7-3 for air compressor over-

load information.

7-3. Air Compressor Overload Protection

See Section 9-5 for engine/generator
overload protection.

Over Pressure Protection

Do not set air pressure above 150 psi
(1034 kPa). If air pressure exceeds

150 psi the compressor clutch will

disengage and shut down the com-

pressor.

If the compressor shuts down due to high

pressure, use the Air Pressure regulator

to reduce the system pressure. See Sec-

tion 7-2.
The compressor is equipped with an

emergency relief valve that will open if

pressure approaches 200 psi (1379

kPa).

Over Temperature Protection

The compressor is equipped with
high oil temperature shutdown. High

oil temperature can be caused by low

oil, hot air recirculation, blocked or

clogged cooler, or fan failure.

When the temperature inside the unit
drops below 45

C), internal

heaters activate to prevent air sys-

tem freeze-up. Ice in air system com-

ponents may cause an Over Pres-

sure condition.
