3.3.3 Pneumatic Requirements
The factory compressed air supply must be "clean (to a 5 micron level), dry and
unlubricated" air with a regulated maximum pressure of 100 psig (690 kPa). Depending
on your application, the welder requires between 35 to 100 psi to operate properly. The
welder includes an in-line air filter. A quick-disconnect fitting is suggested. Use a lockout
device on the air line if required.
CAUTION
The pneumatic system is contained within the welder's enclosure. Refer to
The system consists of:
1. A primary solenoid valve,
2. An air cylinder,
3. A pressure regulator,
4. An air-pressure gauge.
5. Down speed control valve
The horn's rate of descent (downspeed) is adjusted at the front of the actuator using the
Downspeed control knob. The rate of ascent is fixed.

General Warning
Synthetic air compressor lubricants containing Silicone or WD-40 will
cause internal welder damage and failure due to the solvents
contained within these types of lubricants.
There should be no substitute for clean, dry air to run the welder. Use
of other types of gas could lead to premature degradation of seals.
Contact your Branson representative if you have any concerns.
