EXPLOSION HAZARD:
NEVER USE LEAKING THERMAL SPRAY EQUIPMENT.
Place a “Danger Do Not Operate” tag on the defective equipment to
alert others to the unsafe condition.
Obstructed gas lines caused by defective hoses, collapsed hose stems, or
dirt in the gun head gas passages or nozzle jets require excessive gas
pressure to obtain proper gas flow.
If required oxygen and fuel gas pressure are more than 3 psi (0.2 bar) over
the recommended pressure, check for a fouled nozzle or incorrect air cap.
Low pressures often indicate a serious leak. Shut down the equipment and
correct the condition before restarting the system.
EXPLOSION HAZARD:
Acetylene pressures exceeding 15 psig (1.03 bar) may cause the gas to
detonate. If this pressure of 15 psig (1.03 bar) is insufficient, use another
fuel gas.
1.4.3 Compressed
Air
Always refer to gases by their proper names to avoid confusion.
Never use compressed air, oxygen, or fuel gas to clean clothing.
For thermal spraying or blasting operations, use compressed air only at
recommended pressures. Keep the air line free of oil and moisture.
Consult an equipment dealer for filter and after-cooler recommendations.
1.4.4
Flame Spray and HVOF Equipment
Thoroughly read and understand this manual and familiarize all operators
with gun operation before lighting the gun. Maintain guns according to
recommendations.
PERSONAL INJURY (BURN) HAZARD:
Using a match to light a flame spraying gun can result in serious injury.
Use a friction lighter, pilot light, or arc ignition instead.
