Product Information

Product Literature (PDF)

Designed and built to provide maximum reliability in the toughest conditions. This simple to use self-propelled Submerged Arc welding tractor can easily connect to Miller AC or DC Subarc power supplies.

Heavy-duty, four-wheel, chain-driven trackless operation with rubber wheels provides superior and reliable mobility.

Vertical, horizontal and rotary torch adjustment allows for greater access to hard-to-reach spots.

Manual clutch enables freewheeling movement of the tractor.

Travel speed is precisely controlled by a closed-loop microprocessor control with tach feedback.

Easily accommodates a 60 lb (27 kg) wire reel for fewer wire changeovers.

All of the arms, support posts, etc. can be removed with quick acting clamps enabling the carriage to be totally dismantled without tools and easily passed through an 24 in (610 mm) manhole.

Simple and easy changeover from fillet to butt weld configuration.

Available with either the HDC 1500 DX (MT 1500 DX) , or HDC 1500 A (MT 1500 A). (See below.)

HDC 1500DX

  • AC/DC controller
  • CV and CV+C process modes.
  • New CV+C mode allows operator to preset and monitor voltage as well as amperage rather then wirefeed speed.
  • Crater, Burnback and Run-In standard
  • 12 pre-settable and lockable programs.
  • See literature for the full features of this control.

Internal Terminal StripInternal terminal strip allows easy hookup for automatic flux valve, peripheral equipment and provisions to add remote start/stop and inch up/down.

HDC 1500A

Sequence access door allows operator easy access to make weld sequence adjustments.

Indicator light lets operator know that the unit is energized.
