6.1
Preventive maintenance
The LAF 1251 BR requires little maintenance in normal environment and opperation
conditions. It is sufficient to blow it dry clean using dry compressed air free from oil once
a month.
After cleaning the equipment with blow dry air, check that the electric connections and
components are properly fixed. Check for possible faults in the wire isolations or electric
cables, including the welding cable and any others and if any of them is faulty substitute
it.
6.2
Corrective Maintenance
In
order to ensure the perfect functioning and performance of a ESAB equipment, use
only original parts supplied by ESAB or approved by them.
All guarantee undertakings from the supplier cease to apply if the customer uses non-
original or non -approved parts when replacing any of them.
Spare parts can be order from the ESAB Authorized Services or from its Sales
Distributors listed on the last page of this Manual. Always inform the Equipment Model
and Serial Number.
6.3
Inspection and service
Keep equipment in clean and safe operating condition, free of oil, grease, and (in
electrical parts) liquid and metallic particles which can cause short-circuits.
Check for and tighten loose hardware including electrical connections. Loose power
connections overheat during welding.
Immediately replace all worn or damaged power cables and connectors. Check for
frayed and cracked insulation, particularly in areas where conductors enter
equipment.
The electrode wire and all metal parts in contact with it are electrically energized while
welding. Inspect these parts periodically for defective insulation and other electrical
hazards.
Keep power cables dry, free of oil and grease, and protected at all times from damage
by hot metal and sparks.
Clean dirt and metal particles from drive roll groove weekly; replace roll if badly worn.
WARNING
WARNING
If uninsulated cable and parts are not replaced, an arc caused by a
bared cable or part touching a grounded surface may damage
unprotected eyes or start a fire. Body contact with a bared cable,
connector, or uncovered conductor can shock, possibly fatally.
Many troubleshooting situations require that the power remain on
and that power terminals in the equipment carry voltage. Exercise
extreme caution when working on "live" equipment. Avoid contact
with electrical components, except when testing with an appropriate
instrument.
