DESCRIPTION
CAUSE SOLUTION
1) Check the power supply and change the
line fuse if necessary.
1) Check that the air filter is not blocked.
2) Increase the air pressure.
1) Switch on the generator and wait a
few minutes before working again.
2) Call the STEL assistance centre.
1) Press the RESET button.
1) Check the air pressure.
2) Check that the torch cap is well closed.
3) Check that the side panel has been correctly closed
(torch connector inspection side)
1) Reduce the cutting current with the command
on the front panel or reduce the cutting time.
2) Reduce the length of the connecting cable or
increase the cable section.
3) Do not connect other appliances to the same
line as the THOR.
1) Change the worn parts or remove the oxide
with a wire brush.
2) Check the torch and fit spare parts if
necessary.
3) See the yellow SAFETY led on the front panel:
if it is lit, wait until the generator cools down.
4) See the green GAS led on the front panel: if it
is off, increase the air pressure.
4.1) Check whether the air filter is blocked and
replace it if necessary.
5) Check the incoming line. If an extension is being
used, ensure that the cable section is adequate.
1) Check that the earth clamp has a good
contact with the piece to be cut.
2) Check the connection of the positive pole at
output to the socket, even on the inside.
1) Replace the electrode and the tip.
