Component description
13AP1 Main circuit board, with the control electronics (see the description in
section
"13AP1 Control board" , page 21)
13AP2 Circuit board with display, see the description in "13AP2 Digital
display" , page 34. Only for ESABFeed with M13 panel.
13C2 - 13C6 Capacitor, 0.1 µF.
13CXX Capacitor, 4700 µF. Must be fitted when the wire feed unit is used
under difficult applications (e.g. low mains voltage, long cables etc.).
13G1 Feed 484:
All serial numbers. Tachogenerator incorporated in motor 13M2.
Feed 304:
Up to and including serial no. 620-xxx-xxxx. Tachogenerator
incorporated in motor 13M1.
From serial no. 917-xxx-xxxx Pulsegenerator (encoder) incorporated
in motor 13M1.
See "13AP1:10 Tachometer input" , page 27.
13M1 Motor, rated voltage 42 V. Feed 304.
13M2, 13M3 Motor, rated voltage 12 V. Feed 484.
13RP1 Potentiometer, 10 kOhm, for setting the wire feed speed.
13RP2 Potentiometer, 10 kOhm, for setting the welding voltage. Only
ESABFeed with M13 panel.
13RP3 Potentiometer, 10 kOhm, for setting the burn-back time.
13RP4 Potentiometer, 10 kOhm, with incorporated switch, for setting the
crater fill time. Only ESABFeed with M13 panel.
13S1 Microswitch, monitoring the water connection. The pump in the water
cooling unit starts when the switched is closed.
13SA1 Switch, 2/4-stroke changeover. When the switch is closed, 4-stroke
control mode is selected.
13SA2 Switch, creep start function ON/OFF. When the switch is open, creep
start function is operative.
13XP1 Panel plug, for connection to the welding power source.
13XP2 Panel plug, for welding current connection from the power source.
13XS... Connectors with the designation 13XS... are socket connectors.
13XS13 23 pole panel socket for remote control.
13YV1 Gas valve
