pOssiBle cause
remeDY
Insufficient penetration or excessive scoria
settlement.
cutting speed too fast.
touch angle too great.
Work piece is too thick.
electrode and nozzle are worn out.
slow the cutting speed.
Adjust the torch angle.
Confirm work piece thickness and re-check
technical data.
replace electrode and nozzle.
interruption of cutting arc.
cutting speed too low.
excessive distance between torch and work
piece.
electrode is worn out.
intervention of the protection system.
increase the cutting speed.
decrease the distance between torch and
work piece.
replace electrode and nozzle.
check warning lights and take appropriate
action.
the torch is cutting at tilt when you wish it to
be perpendicular.
torch position not correct.
Asymmetric wear of nozzle hole and/or wrong
assembly of torch parts.
re-align the torch.
check assembly (see fig.6) and change
nozzle if necessary.
excessive wear of nozzle and electrode.
Air pressure too low.
contaminated air (humidity-oil).
excessive pilot arc ignitions in the air.
nozzle holder damaged.
increase air pressure.
check air supply system.
do not casually turn the torch on and off.
change the nozzle holder.
