ERGOFRESH MIG WELDING TORCH
MAINTENANCE
Turn off the welding equipment and disconnect the welding torch before performing torch maintenance. Replacement of spare
parts or other maintenance must be performed after the torch has cooled down.
For any repairs, contact an authorized dealer or service workshop.
Daily maintenance
On the torch front part, check that:
1. All insulations are undamaged and
intact.
2. Gas nozzle is intact and suitable for
work.
3. Shielding gas flows freely and steadily.
4. Filler wire is intact and suitable for work.
5. Fastening parts are intact and fastened
tightly in place.
6. Check all the cables and connectors. Do
not use them if they are damaged.
TROUBLESHOOTING
The problems and the possible causes listed are not definitive, but suggest some typical situations that may turn up during normal
use of the welding equipment. For further information and assistance, contact your nearest authorized dealer or service workshop.
General
The welding does not start:
• Check that the earth return cable is
properly connected.
• Check that the welding system is also
otherwise in a proper working order.
The welding system stops working:
• The torch may have overheated. Wait for
it to cool down.
• Check that the cables have not become
loose.
Welding torch
The torch overheats:
• Make sure the torch body is properly
connected.
• Make sure that the welding parameters
are within the range of the welding torch.
If different torch components have
separate limits for the maximum current;
the lower one of these is the maximum
current that can be used.
• Make sure the coolant circulation is
working normally (with water-cooled
systems).

On the torch cable, check that:
1. Torch cable insulations and connectors
are intact.
2. There are no sharp bends in the torch
cable.
3. Components are tightly fastened.
4. Check that the current transfer surface
on the torch current connector is clean
and undamaged.

for damage.
• Make sure you are using original
Trafimet consumable and spare parts.
Incorrect spare part materials may also
cause overheating.
• Make sure the connectors are clean,
undamaged and properly fastened.
Weld quality
Dirty and/or poor weld quality:
• Check that the shielding gas has not run
out.
• Check that the shielding gas flow is
unobstructed.
• Check that the gas type is correct for the
application.
• Check that the welding procedure is
correct for the application.
Varying welding performance:
• Check the filler wire size, type and wear.
• Check that the welding torch is not
overheating.
• Check that the earth return clamp is

Periodic maintenance
Only qualified service personnel
is allowed to carry out periodic
maintenance.
The electric connectors of the unit require
checks at least every six months. Also
cleansing of any oxidized parts and
tightening loose connectors is required
periodically.
Arc is not ignited:
• Protective hose or another insulation of
torch is broken.
• Torch is wet.
Gas shielding is bad (weld pool "boils",
electrode gets oxidized):
• There are impurities in shielding gas
(moisture, air).
• There are impurities in base material
(rust, base coat, grease).
• Impurities stuck on gas nozzle.
