© ESAB AB 2018

When the wire feed unit is connected to a power source with steplessly variable output
voltage, potentiometer 13RP2 on the front of the unit can be used to control the power
source output voltage.

The +15 VB and 0 VB voltages are supplied by the power source via connector XP01. The
voltage adjustment circuits are not galvanically isolated from the other circuits on circuit
board 13AP1.

The remote control unit for voltage control is connected to pins J, K, L, Z and Y in connector
13XS13. A link must be fitted between pins Z and Y in order to activate the unit.

13AP1:5 Gas valve

The gas valve is connected to connectors F04 and F05. If an intermediate wire feed unit is
being used, its gas valve is connected via pins V and U in the remote control connector
(13XS13).

13AP1:6 2-stroke / 4-stroke
