Welding on the carrier or harvester head

IMPORTANT: Electrical welder current can damage

electrical components. Always ensure that you
isolate the electrical system before welding.

NOTE: turning the switch to the OFF position

is not sufficient.

1. Park the carrier and place the harvester head on a

flat, even surface.

2. Turn the Waratah switch to the OFF position.

3. Turn off any electronics that are wired directly from

the battery.

4. Turn off the main power to carrier.

5. Disconnect the carrier battery, followed by the

connectors on the base and cab controllers.

6. Disconnect the Waratah control module and PC

connectors when welding on the harvester head.

7. Disconnect the J1, J2, and J3 plugs from the head

module (HHC) when welding on the harvester head.
Disconnect the base module, PC, and flexbox
connectors when welding on the carrier.

8. The attachment is manufactured from high-tensile

steel, so only use low-hydrogen (E11018-M) welding
rods on it.

9. Clean the area of any oil, paint, and rust contaminants.

These would make the weld brittle

10. Ensure the welding earth is directly attached to the

item being welded.

11. Preheat weld area according to the table below.

NOTE: Measure the temperature 300 millimetres

(11.8 inches) from the weld in each direction
for a good heat soak.

Metal Thickness

Pre-heat Temperature

6–20 mm (0.2–0.8")

20–150 °C (68–302 °F)

20–50 mm (0.8–2.0")

50–175 °C (122–340 °F)

12. When welding multiple runs, allow temperature to drop

down to specification before starting the next run.

ture—Torque...................................................................... 1750–2200 °C

3179–3989 °F

13. Allow the weld to cool slowly. Rapid cooling can cause

cracking.

14. Re-connect the connectors to the controllers, the

harvester head, the solenoid, and the sensor harness.

15. Re-connect the carrier battery.
