6.2 Function explanations
6.2.1 Overheating protection
The power source has one thermal overload trip which operates if the internal
temperature becomes too high, interrupting the welding current and lighting the
orange indicating lamp on the front of the unit. It resets automatically when the
temperature has fallen and the indicating lamp will go out.
6.2.2 Water connection
The ESABFeed has a sensor ELP , ESAB L ogic P ump, that senses if the water
hoses of the welding gun are connected. When a water cooled welding gun is
connected, the water pump starts.
When using other wire feed units, the water pump switch must be in position ”I” when
a water cooled welding gun is used.
When connecting the cooling water hoses to/from the ESABFeed wire feed unit, the
mains ON/OFF switch of the ESABMig must be in the OFF position.
When a self cooled welding gun is used the pump switch must be in position
”ELP/0”.
Note, if a water cooled welding gun is used when the pump is inactive, the welding
gun might be damaged.
6.2.3 Water flow guard
The water flow guard interrupts the welding current in the event of loss of coolant
and an orange indicating lamp on the front of the power source lights up.
The water flow guard is an accessory. Ordering number see on page 45.
6.2.4 Inductance
Higher inductance produces a more flowing weld and less spatter. Lower inductance
produces a harsher sound and a stable, concentrated arc.
7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Maintenance must be executed by a professional.
Only those persons who have appropriate electrical knowledge (authorised
personnel) may remove the safety plates.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
