6. Maintenance
Risk of bodily injuries:
Before performing any inspection or maintenance, always unplug the welding torch. Make sure
that the power supply cannot be turned on by anyone else. Risks of bodily injuries from flying
particles.
Always wear appropriate protective wear, safety goggles and respiratory protection!
Due to the use of high-quality components, our extraction torches need little maintenance. In order
to optimize efficiency and to ensure continued functionality of the torch we recommend regular
maintenance. Individual checks and maintenance tasks should be performed at regular intervals,
depending on the conditions under which the welding torch is operated. We recommend the
creation of individual maintenance schedules for each user individually. All regular and scheduled
maintenance of the welding torch should be recorded.
To help ensure trouble-free functioning, the following inspections should be made at
regular intervals:
• General visual inspection of the welding torch for any sign of damage or wear.
• Check all removable connectors to ensure that they are properly situated.
Replace the following items as needed:
• Insulating inserts
• Contact tips,
• Gas nozzle and all other consumables.
• To avoid leakage, check the connectors and connecting hoses. Avoid undue torsion and
traction on the torch.
• Depending on the wire quality, remove any abraded wire and change the liner regularly.
6.1 Changing the liner
Loosen the knurled nut holding the liner on the EURO-connector using MIG helper pliers (ET001W).
Pull out the old liner and blow out the liner with compressed air (max. 6 bar). Press the liner all
the way into the torch assembly until it rests against the contact tip and hold it there. Now gently
tighten the knurled nut on the EURO-connector and cut the liner close to the EURO-connector.
According to the wire diameter, we recommend the use of the installation tool from WELDABILITY
SIF. Attention: If the clamping screw which secures the liner is fastened too tight, it will deform the
liner and impede the feeding of the wire.
