Control Panel And Connections - ESAB MEK 4 Service Manual

CONTROL PANEL AND CONNECTIONS

1. Cooling water connections
(only - -882 and - - 883 models).
2. Gas connection.
3. Connector for control cable from the
power unit.
4. Connector for welding current cable from
the power unit.
5. Switch, crater filling On/Off.
Crater filling operates only with the LAW
power units.
6. Digital instrument (only - - 881 and - -883
models). Operates only with the LAW
power units.
7. Potentiometer, wire feed speed 1.9 - - 25
meter per minute.
8. Potentiometer, welding voltage control.
Operates only with thyristor- -controlled
or transistor- -controlled power units.
9. Connector, remote control unit. Control is passed to the remote control unit
automatically when it is connected.
10. Cooling water connections to/from the welding gun (only - -882 and - - 883 models).
11. Strap securing points. The strap must be used to secure the wire feed unit to the power
unit during transport.
12. Hole for fitting connector for PKE (welding gun with integral wire feed drive motor).
13. Welding gun connector.
14. Selector switch, 2/4- -stroke mode.
15. Potentiometer, burn- - back time, 0 - - 0.5 seconds.
16. Potentiometer, crater fill time, 0 - - 5.1 seconds.
17. Link, creep start On/Off.
A: Creep start active. Wire feed starts at 1.9 m/min and then increases to the set speed.
B: Normal start. Wire feed starts at the set speed.
See also Creep / Normal start on page 17.
18. Brake hub.
The hub is adjusted when delivered, if readjustment is required, follow the instructions
below.
Adjust the braking power by means of the two screws (springs) inside the hub.
Turn the adjustment screws clockwise to reduce the braking power.
Adjust the brake hub so that wire is slightly slack when wire feed stops.
