HDT-1000 / SET-UP & OPERATION
1. Remove the machine from the shipping box. Be sure to account for all loose parts before discarding
the box!
2. Locate the cords that ship with the machine. A power cord and control pendant cord should be
included. The cable connectors are keyed to fit their appropriate mates on the tractor and pendant.
Install the power cable and pendant cable to their respective panel connectors on the tractor.
3. The operation of the tractor is handled on the control panel of the submerged-arc wire feeder control
box.
4. If the follower arms are to be used, install them on the front and back of the machine. Make sure that
the front follower arm is located in the short position. This guides the front of the machine into the fillet
member, allowing the tractor to track a straight line.
5. Install the welding interface cables from the welding power supply to the wire-feeder control box. Also
install the weld current cabling from the wire-feeder control box to the submerged-arc nozzle. Refer to
the NA-3 instruction manual that ships with the HEAVY-DUTY TRACTOR.
6. Load the wire-reel with the appropriate sized welding wire. Again, refer to the NA-3 instruction
manual for proper installation of wire through the feeder and nozzle.
7. DRY RUN:
To ensure proper operation of the unit, test by turning the main power on from the feeder control
panel. Switch the tractor travel direction switch to the desired travel direction. Switch the HAND /
AUTO switch to HAND. Adjust the speed with the knob located below the LED speed display.
8. All welding parameters and tractor controls are fully adjustable during cycle operation.
NOTE: The HDT-1000 version comes without a power cord since it draws its power from the
120VAC provided to the NA-3S feed control unit from the welding power supply. It is possible to
rewire the tractor to receive power from the AC lines. However, this is not needed when pur-
chased with the welding equipment. Consult Weld Tooling’s sales department for application
assistance.
