Problem
Cause
Solution
1
Leak gas
and/or flame in
the joint of
torch and
torch cutting
tip.
1. The torch holder inlet is damaged.
2. There is copper burr or materials on the
surface of the torch tip.
1. Softly grind the torch cone with small sand paper to clean
out the burr.
2. Clean the material on the cutting tip. Softly grind the
surface with small sand paper. Change the cutting tip if it is
badly damaged.
2
The flame
goes out as
soon as the
oxygen valve
is opened
The cutting oxygen leaked into the preheating
oxygen area.
1. Copper stain or useless materials on the inner
part of torch
2. The smaller cone of torch cutting mouth was
stuck with some with material or was damaged.
1. Softly grind the most inner part of torch holder with sand
paper to clean out the debris or damage.
2. Softly grind the smaller surface of the cutting mouth.
Change the cutting mouth if it is serious damaged.
3
The steel can’t
be cut through
1. The torch cutting-tip is too small.
2. The flame frequency is not strong enough
3. Low pressure for cutting oxygen
4. The hole channel of cutting mouth may be
jammed
5. The cutting oxygen is not pure.
6. The cutting oxygen was leaked into the
preheating oxygen hole channel.
1. Choose the cutting tip spec according to the cutting
thickness.
2. Increase flame frequency properly.
3. Properly increase the cutting oxygen to ensure the enough
flow speed of cutting oxygen.
4. Clean the useless materials in the torch cutting mouth with
cutting pin.
5. Use oxygen with more than 95% purity.
6. Clean the useless materials on the cutting mouth and
torch, repair the damaged surface and change cutting mouth
if needed.
4
The cutting is
not straight
enough.
1. The steel pipe was deformed.
2. The flame line was not straight.
3. Uneven pipe surface
4. The torch was poorly fixed and can be moved.
5. The chain is not straight
1. Use round steel and calibrate it before cutting.
2. The torch should have a 90
o
angle with the steel and tightly
fixed. Clean the useless materials in the torch cutting mouth
with cutting pin.
3. Fix surface irregularities.
4. Tighten all connections.
5. Straighten the chain.
5
The clutch will
not engage.
1. The clutch carriage is damaged
2. The clutch is dirty
1. Repair or replace the carriage
2. Lubricate the clutch and ensure it moves freely
