Helix™T55

1BASIC INFORMATION 1

BASIC INFORMATION

The T55 Helix™ is a precision, gear driven weld

head designed for GTAW (TIG) welding. Paired

with the specifically designed steel and chromoly

track ring, the Helix™ provides strong, reliable

welds for a rugged and stable welding solution.

The T55 Helix™ tractor is controlled by a handheld

controller and AVC. It features an easy release

clutch which disengages the drive roll allowing free

movement along the track, without removing the

unit from the track ring. A heavy duty Nylon cover-

ing protects power, control, water and gas cables

from wear and tear; and a high temperature Teflon

coated sleeve protects the area closest to the weld

head.

The standard T55 weighs in at 35 lbs., without the

wire arms, and has two handles for easy carrying.

Two wire arms come standard with the option to

remove one of the arms for added versatility. The

Weld Head has 1”of oscillation stroke allowing the

operator flexibility when installing the Weld Head

and Track Ring. 3. 5” of AVC stroke allows the op-

erator to weld in deep groove applications. Torch

and Arc orientation can be adjusted 140° to adjust

for numerous weld parameters. Precision motors

allow for travel speeds from 0.5 IPM to 20 IPM.

The track ring is a low profile heavy duty track ring

stabilized at even intervals with cross braces.

Mounting shoes, containing spring cushions rated

to 800lb, attach to the cross braces and allow for

the work surface’s heat expansion which stops

binding and ring distortion. The geared system of

the track eliminates slippage and the angled section

interface prevents tractor jump.

The T55 Helix™ comes fully assembled in a rugged

waterproof case along with a gas line, water in and

water out, power cable, control cable, and a Helix™

tool box.

Toolbox

Included with the Helix™ is a toolbox of common

tools and consumables. These tools are for general

operation and maintenance; more in-depth mainte-

nance may require additional tools.
