K325HCS - Lincoln TC-3 High Capacity Beam Travel Carriage for Submerged Arc

Precision Automation for Heavy Fabrication

The Lincoln Electric TC-3 Self-Propelled High Capacity Travel Carriage (K325HCS) is an industrial-grade automation solution designed to enhance the efficiency and consistency of submerged arc welding operations. Engineered for heavy-duty environments, this carriage serves as the mobile backbone for automated welding setups, capable of transporting welding heads, control boxes, and wire handling equipment along a beam with exceptional stability and precision. It is specifically built to handle the rigorous demands of structural steel fabrication, shipbuilding, and heavy equipment manufacturing where long, continuous welds are required.

One of the standout technical advantages of the TC-3 is its sophisticated drive system. Unlike older mechanical carriages that require time-consuming gear changes to alter travel speeds, the TC-3 features a continuous speed control system. This allows operators to dial in precise travel speeds ranging from 5 to 75 inches per minute (0.1 to 1.9 meters per minute) seamlessly. This flexibility is critical when transitioning between different material thicknesses or welding procedures that demand specific heat input management. The unit operates on standard 115V AC, 50/60 Hz power, making it easily compatible with auxiliary power available from most industrial Lincoln Electric power sources.

The K325HCS is designed for versatility in complex welding configurations. It is robust enough to support Tandem Arc installations involving two or three weld heads, as well as Twinarc®-tandem setups utilizing up to four wires. This high load capacity ensures that facilities can maximize deposition rates without compromising the stability of the travel mechanism. The carriage measures 26.5 inches in height, 19.25 inches in width, and 14.75 inches in depth, providing a substantial platform for mounting equipment while remaining compact enough for standard beam integration. Whether integrated into a fully automatic system triggered by weld controls or operated manually for setup and positioning, the TC-3 delivers reliable, bi-directional performance essential for modern high-throughput welding lines.
