HDT-1250/1252/1254 / SETUP AND 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 pendant. Install the control pendant onto the free
side of the control pendant cable.
4. If the weld contactor switches on the pendant are to be used, wire up the welding power supply’s
remote contactor circuit to the supplied, four-terminal cable connector.
5. 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 shorter of the two possible positions. This guides the front of the
machine into the fillet member, allowing the tractor to track a straight line.
6. Install the welding equipment to be used with the tractor. The mounting plates are supplied with the
tractor. It is the customer’s responsibility to add the appropriate mounting holes to the mounting plates
for their equipment. If assistance is required, contact Weld Tooling Corporation’s sales department
for application assistance.
7. DRY RUN:
To ensure proper operation of the unit, test by turning the main power on from the feeder control panel
if used in this configuration or by plugging the tractor into a power source. Switch the tractor travel
direction switch to the desired travel direction on the pendant. Adjust the speed with the knob located
below the LED speed display.
8. All tractor controls are fully adjustable during cycle operation.
NOTE: The tractor can easily be re-wired to draw 120VAC power from the wire-feeder or welding
power supply outputs. The default configuration for the HDT-1250/1252/1254 is to get power from
the AC lines through the supplied power cord. However, HDT-1252/1254 (240, 42 VAC ver-
sions) cannot be re-wired for operation with welding power supply or feeder equipment,
only HDT-1250 (120 VAC version). See page 9 for details.
