9.0 TROUBLESHOOTING
This guide is intended to assist in determining the probable causes of torch
malfunction and their associated repairs.
For each potential problem identified, a probable cause and recommended repair
procedure is listed.
9.1 Oxygen Leaks
1.
Oxygen leaks at hose adapter: Oxygen hose fittings are not tight enough.
Tighten fittings and test with soapy water. Formation of bubbles identifies
location of leak. A persistent leak can often be corrected by the use of PTFE
tape.
2.
Oxygen leaks at collet nut: The cutting rod is not seated against the neoprene
collet washer, or the collet washer may be dirty, worn or missing. Loosen the
collet nut 1/2 turn, firmly seat the rod and tighten the collet nut. If leak
persists, remove the collet nut, collet and collet washer. Clean or replace the
collet washer. If a collet washer is worn and a new one is not available, turn
the washer over and replace with the least worn face exposed.
3.
Oxygen leaks at the control valve nut:
a.
The rubber gasket is dirty or worn. Remove and clean or replace as
needed.
b.
The valve stem o-ring is dirty or worn. Follow control valve disassembly
procedures to remove valve stem. Clean or replace as needed.
c.
The valve stem washer is dirty or worn. Follow control valve disassembly
procedures to remove the valve stem washer. Clean or replace as needed.
d.
The valve stem is worn. Replace the valve stem and install a new o-ring.
e.
The control valve nut is loose. Partially unscrew the control valve nut.
Ensure the rubber valve nut gasket is in place. Retighten as described in
the control valve reassembly procedures.
