ESAB Bombardier Digipulse Dual Wire Feeders User manual

Brand: ESAB

Model: Bombardier Digipulse Dual Wire Feeders

Type: User manual

ESAB Bombardier Digipulse Dual Wire Feeders are designed to provide precise control over the welding process, enabling operators to achieve high-quality welds with increased productivity. These feeders offer a range of advanced features that cater to various welding applications.

The Crater Fill feature allows users to preset specific welding parameters, including wire feed speed, arc length, and time, to control the shape and size of the weld crater upon completion of the welding process. This feature helps to prevent weld defects and improve the overall quality of the weld.

With 16 unique crater fill conditions and two unique crater fill times, the Digipulse Dual feeders provide flexibility and customization for different welding requirements. The "double click" method of changing torch schedules is automatically disabled when a crater time is programmed, ensuring precise control during crater fill operations.

INSTALLATION AND OPERATION

Bombardier Digipulse Dual Wire Feeders

(this kit is designed for the Bombardier Digipulse Dual Feeder only)

INSTALLATION (See Figure 1.)

TO PREVENT ACCIDENTAL ELECTRIC SHOCK, BE

SURE FEEDER CONTROL CABLE IS DISCON-

NECTED FROM THE POWER SOURCE BEFORE

WORKING INSIDE WIRE FEEDER.

1. Make sure control cable is disconnected from the

Power Source or Digipulse Dual Wire Feeder.

2. Remove the cover of the Digipulse Dual control

box.

3. Remove the plastic knock-out plug in the center of

the Digipulse feeder front panel.

4. Position the Crater label (P/N 954754 supplied in

kit) over the hole in the control front panel and press

firmly in place.

5. Insert and mount the supplied crater toggle switch

assembly in the front panel center hole using the

hardware provided. Rotate the switch so that the

white wire is on top (12 oclock) position and the

blue wire at the bottom (6 oclock) position. See

Figure #1 on reverse side.

6. Remove plug P6 from the MPU PC board and in-

sert the white wire connector into plug terminal po-

sition #14 (P6-14) . The wire connector will lock

into position when inserted properly.

7. Insert the blue wire connector into terminal posi-

tion #2 (P6-2) of plug P6. The wire connector will

lock into position when inserted properly.

8. Connect the yellow wire with the spade connector

to the terminal strip (T1-1) in the Digipulse Dual

control box at position #1 (common).

9. Reconnect the P6 plug to the MPU PC board.

10. Remove EPROM 18090 from the MPU PC board

and replace it with EPROM 99513606 supplied with

the kit. EPROMs are static sensitive so handle with

care. Note the orientation of the notched end of

the EPROM. Notch should be facing left.

11. Replace wire feeder control cover and connect the

control cable to Power Source.

OPERATION

The Crater Fill feature allows the operator to preset a

special welding wire feed speed (IPM), arc length

(VOLTS) and time (TIMES) to control the shape and

size of the weld crater upon termination of the welding

process.

Each weld schedule can be preset with a unique crater

fill IPM and VOLTS condition but only one crater fill

TIME can be programmed for each torch. The

Digipulse Dual feeder can have 16 unique crater fill

conditions and two unique crater fill times.

Note

When a crater TIME is programmed, the double click

method of changing torch schedules by using the weld-

ing torch trigger is automatically disabled for that torch.

Programming a Crater Condition

1. Momentarily depress the trigger of the torch to be

programmed. Be sure the desired schedule num-

ber is assigned to that torch. Schedules 1 - 4 are

Pulse arc welding schedules and schedules 5 - 8

are Short Circuiting/Spray arc welding schedules.

2. Hold the Crater toggle switch in the TIMES posi-

tion. The window corresponding to the torch be-

ing used will illuminate. Simultaneously enter the

desired crater time (in seconds) using the INC/DEC

switch under the illuminated window. A zero (0)

will disable the crater fill feature. For example, if

the left torch trigger was depressed (see step #1)

then the IPM window will illuminate.

3. Hold the Crater toggle switch in the CONDITIONS

position and simultaneously enter the crater IPM

and VOLTS settings desired using the INC/DEC

toggle switches beneath their respective window.

4. During welding the crater fill schedule will be en-

abled when the operator releases the torch trig-

ger. The crater timer will start and the arc will ex-

tinguish automatically when the preset crater time

has timed out.

Be sure this information reaches the operator.
