5 Maintenance and repairs
Danger!


Danger of burn injuries!
Gas nozzle and torch head get very hot during welding. Let the torch cool down prior to
doing maintenance work!

5.1 Regular checks

To assure a faultless function and long life of the equipment, torch and cable assembly must be checked and
serviced regularly:
General
Daily
Subject to change without notice.  2020 TBi Industries GmbH
Before performing maintenance on the system, the main power of the installation
must be turned off. The safety instructions at the beginning of this manual
must be observed.
Damaged torches or cable assemblies must not be used any more! Known defects
must be repaired by qualified personnel prior to the next use of the equipment.

Check the torch and cable assembly for damages before every use. Damages
must be repaired by qualified personnel prior to further use of the product. This is
especially important in regard of damages on the electrical insulation of the torch
or cable.

Cleaning and maintenance work must be done at the latest, if the welding
performance is degrading.

The contact tip should be exchanged if the inner hole is countersunk or if there
are ignition problems

Change the contact tip and the liner if there are wire feeding problems. Take
care to install the new liner correctly and precisely fit it to the length of the cable.

Blow out the torch with compressed air every time the wire guide is changed to
remove wire abrasion. (with dry and oil-free air)

For water-cooled welding torches, pay attention to the cleanliness of the cooling
liquid in the system, change if necessary. Contamination of the cooling water can
clog up the water pipes in the system.

The use of a high quality anti-spatter spray or anti spatter paste is highly
recommended and will tremendously increase the life time of the consumables.

Worn and damaged torch parts must be replaced with original TBi spare and
wear parts immediately.

Visual inspection for damages – e.g. bends or cracks.

Torch cleaning/maintenance:
Contact tip and gas nozzle should be cleaned as soon as there is noticeable
spatter adhesion. It must be avoided that a spatter bridge will build up between
contact tip and gas nozzle, the torch could be damaged.
The gas nozzle should be cleaned regularly on the inside to prevent adhering
spatter from causing
gas swirling.

Contamination and wire abrasion can settle in the drive system (drive roll, drive
shaft and counter-pressure roll). Clean the drive system every day with dry, oil-
free compressed air as preventative maintenance. Wipe the drive shaft with a
clean cloth every time the drive roll is changed.

Note: Do not oil or grease the drive (drive roll, drive shaft and counter-pressure
roll)
