connecting a water-cooled welding gun, the water pump starts.

Detection only works with power sources that are equipped with ELP.

Wire feed pressure

Start by making sure that the wire moves smoothly through the wire guide. Then
set the pressure of the wire feeder's pressure rollers. It is important that the
pressure is not too great.

Fig 1

Fig 2

To check that the feed pressure is set correctly, you can feed out the wire against
an insulated object, e.g. a piece of wood.

When you hold the gun approx. 5 mm from the piece of wood (fig. 1) the feed
rollers should slip.

If you hold the gun approx. 50 mm from the piece of wood, the wire should be 
fed out and bend (fig. 2).
