Lincoln TC-3 High Capacity Beam Travel Carriage for Submerged Arc

Take the Strain Out of Long Welds

For professional welders and fabricators tackling massive structural projects, consistency is everything. The Lincoln Electric TC-3 Travel Carriage is your partner for long, heavy-duty submerged arc welds. Instead of manually managing travel speed or fighting with inconsistent mechanization, the TC-3 rides the beam smoothly, carrying the heavy lifting of the weld heads and controls for you. This allows you to focus on the arc and the weld quality rather than the mechanics of movement. If you are running long passes on bridge girders, ship decks, or heavy pressure vessels, this carriage transforms the job from a physical endurance test into a precision operation.

Setting up the TC-3 is straightforward and welder-friendly. The days of stopping to swap out gears just to change your travel speed are over. This unit features a continuous speed control knob that lets you fine-tune your travel speed from 5 up to 75 ipm on the fly. Need to slow down for a root pass or speed up for a fill? Just adjust the dial. It runs on standard 115V power, which you can usually pull right from your welder's auxiliary outlet. The carriage is built to move in either direction, giving you the flexibility to set up your workflow however the shop floor dictates.

This isn't just a light-duty tractor; it's a high-capacity workhorse. It is built to carry the weight of Tandem Arc or Twinarc® setups, meaning it can handle multiple heads and heavy wire spools without stuttering or slipping. Whether you are running a single heavy sub-arc wire or a multi-wire high-deposition setup, the TC-3 provides the steady, rock-solid travel speed you need to prevent defects like lack of fusion or inconsistent bead profile. It operates automatically alongside your weld controller, starting and stopping with the arc, or you can switch it to manual mode to jog it into position before the arc strikes. It’s a reliable piece of gear that helps you put down perfect metal, foot after foot.
