1. Daily Precautionary Checks
1.1. For any abnormal vibrations, sounds or odours.
1.2. For any sign of overheating on cable connections.
1.3. Whether the power switch is operational and the fan operates smoothly
when the machine is switched on.
1.4. Whether cables are correctly connected, insulated and in sound order.
1.5. Torch consumables are subject to wear and tear and should be replaced
when worn..
2. Three to Six Monthly Check List
2.1. Dust Removal
Remove the side cover plate and clean off all parts with dry compressed air.
Since the effective cooling of the machine is dependent on a designed air flow
pattern, it is important to return the side cover plate after the cleaning operation.
Not paying attention to this detail, will result in over-heating of and consequent
damage to the transformer and semi-conductor parts.
2.2. Wire Feeder Parts
The guide tube, drive rolls and tensioner rollers are subject to wear and tear and
should be checked and replaced if worn.
Common Machine Malfunctions and Solutions
Warning: Machine maintenance and repair must be carried out by
qualified technicians. The operating voltage in the machine can be up to
600V and it is important that power be cut at the machine and at the control
box before covers are removed and repairs carried out. A cooling-down
period of at least 5 minutes is required before commencement of any
inspection and repairs. This will allow the capacitor to fully discharge.
