2 Product description

2.3.2.2 Water cooling

2.3.2.2 Water cooling
Overview
Resistance welding equipment develops very high secondary currents. The heat
is generated primarily at the electrode tips where the resistance is greatest and
internally inside the transformer.
Insufficient water cooling can cause failure to welding equipment, reduce the
durability of components and produce poor welds. Therefore the water flow should
be monitored regularly.
The illustration below shows the water circuits in a welding gun in general. Green
hose is water inlet. Red and black are water outlets.
