7 SERVICE AND MAINTENANCE
WARNING!
Before performing maintenance on the system, the main power of the installation
must be turned off. Please note the safety regulations at the beginning of this
manual.
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.
WARNING!
Risk of burn injuries! Gas nozzle and torch head get very hot during welding. Let
the torch cool down prior to doing maintenance work.
WARNING!
In order to prevent personal injuries or damage to your installation, the following
instructions must be followed:
1. Repair of the KSC-2 or FLC-2 torch mount, the KS-2 safety-off mechanism,
the cable assembly, or the Infiniturn media coupling must only be carried out
by ESAB service support.
2. The Infiniturn media coupling must never be opened. It contains no
user-serviceable parts and will be destroyed by disassembly.
3. Never disassemble the KSC-2 or KS-2. This is a spring loaded mechanism.
Improper manipulation can lead to severe injury.
7.1 Mandatory checks and actions
Before every use:
• Check torch, contact tip, gas nozzle, neck liner, cables, and overall equipment for general
damage
NOTE!
To minimize down-time it is recommended to alternate between two torch necks,
always having a freshly equipped torch neck at hand and ready for use.
Every 8 hours of use:
• Change contact tip.
Daily:
• Do a functional check by hand of the safety-off mechanism.
• Do a visual inspection for damage - e.g. bends or cracks.
• Verify the correct position of the wire feeder. The cable assembly must not be too tense
or sagging.
• Inspect the media connections and the Infiniturn media coupling for leakage.
• Perform cleaning and maintenance of the torch according to the torch manual.
Every 40 hours of use:
• Change wire liners.
• Change neck liners.
