Page 60

10-6. Adjusting Compressor Air Pressure

Tools Needed:

5/16, 3/8 in

Check compressor air pressure using air pressure gauge known to be accu- rate. If necessary, adjust air pressure as follows:

1 Screw

Loosen jam nut securing screw. Turn screw clockwise (increase pressure) or counterclockwise (decrease) until pressure is 125 psi (862 kPa).

.Maximum weld output is reduced

if compressor air pressure is set above 125 psi (862 kPa).

Tighten nut.

2 Pressure Relief Valve

Pressure relief valve opens and re- leases pressure at 150 psi (1034 kPa). The pressure relief valve is not adjustable.
