ESAB Spot/Burnback/Pre-Flow Post-Flow/Trigger Lock Option Module Installation guide

Brand: ESAB

Model: Spot/Burnback/Pre-Flow Post-Flow/Trigger Lock Option Module

Type: Installation guide

ESAB Spot/Burnback/Pre-Flow Post-Flow/Trigger Lock Option Module allows for precise control over welding parameters, enabling spot welding and trigger latch functions. With pre-flow, post-flow, and burnback controls, you can optimize welding quality and reduce spatter. The spot welding function provides accurate timing for consistent spot welds, while the trigger latch feature maintains the welding arc even after releasing the trigger, increasing productivity. This option module enhances the versatility of your wire feeder, making it suitable for a wide range of welding applications.

SPOT/BURNBACK/PRE-FLOW

POST-FLOW/TRIGGER LOCK OPTION MODULE

P/N 34182

for 4HD and 2E Wire Feeders

INSTALLATION

TO PREVENT ACCIDENTAL ELECTRIC SHOCK, BE SURE CONTROL CABLE IS DISCONNECTED

FROM POWER SOURCE OR INTERFACE BOX BEFORE WORKING INSIDE THE WIRE FEEDER.

1. Make sure control cable is removed from the Power Source or Interface Box.

2. Remove the outer cover from the wire feeder.

3. Remove the blank panel from the rear of the wire feeder and install the option module using the screws which

were removed from the blank panel. Refer to Figure 1 for installed position.

4. Locate and remove the jumper plug from the P5 connector on the speed control board (PCB1). DO NOT

DISCARD the jumper cable. If for any reason the option module is removed, the jumper must be reinstalled for

proper operation. Connect the cable supplied with the option module between the P1 connector of the module

board and the P5 connector of the speed control board.

5. A GRAY and a VIOLET wire have been added to the main wire harness and have been left disconnected at the

rear of the wire feeder. Locate these wires and connect the GRAY and VIOLET wires from the option module

to them.

6. A current detector assembly (Figure 1) has been supplied with the option module. The current detector is

required for operation of the spot time and trigger lock functions. The current detector consists of a "U" shaped

steel piece and a reed switch assembly. Between the torch connection and the wire drive stand there is a brass

connection tube. Behind the connection tube there is a feed through bushing. To install the current detector,

first connect the leads from the reed switch assembly to the male quick connect tabs on the feed through bushing.

Slip the "U" shaped piece over the connection tube with the open end down. Remove one nut from the reed

switch assembly and adjust the other nut to the end of the threads toward the leads. Slip the reed switch through

the holes in the "U" shaped piece with the leads facing away from you and install the other nut. Do not overtighten.

7. Reinstall the outer cover of the wire feeder and reconnect control cable.

SETUP

1. Set the PRE-FLOW, POST-FLOW, and BURNBACK controls for the desired times (clockwise increases time).

2. If spot welding is desired, place the CONTINUOUS/SPOT/TRIGGER LATCH switch in the SPOT position and

set the potentiometer to the desired time. Timing will not begin until welding current is detected.

3. If TRIGGER LATCH is desired, place the CONTINUOUS/SPOT/TRIGGER LATCH switch in the TRIGGER

LATCH position.

NOTE

• The trigger will not latch unless current is detected prior to release of the trigger.

If the arc is broken while the trigger is latched, the trigger will unlatch approxi-

mately three seconds after loss of current detect.

• SPOT and TRIGGER LATCH cannot be used simultaneously.
