Water connection

When connecting a water-cooled welding gun, the power source's main power
supply switch must be in the Off position and the cooling unit switch must be in
position "ELP/0".
The wire feed unit with water connection is equipped with a detection system ELP
(ESAB Logic Pump) which checks that the water hoses are connected. When
connecting a water-cooled welding gun, the water pump starts.
Detection only works with power sources that are equipped with ELP.
5.3

Starting procedure

When the wire feed starts, the power source generates welding voltage.
If there is no welding current flow within three seconds, the power source switches the
welding voltage off. The wire feed continues until the welding gun's switch is switched
off.
