Precision Engineering for Demanding Fabrication The Li’l Runner CDL welding tractor represents the next generation of portable mechanization, designed to deliver consistent weld quality in environments where cabling is prohibitive. Utilizing the advanced CAS LiHD battery interface, the carriage provides high-performance mobility for continuous butt and fillet welding without the traditional concerns of power cords.
Advanced Drive and Control Architecture The unit is propelled by a heavy-duty four-wheel drive system enhanced with permanent magnetic traction. A sophisticated closed-loop control system actively monitors and adjusts travel speed, ensuring uniform heat input and stable travel regardless of the welding position. This mechanical consistency results in repeatable weld bead geometry that strictly adheres to specifications, minimizing overwelding and lowering consumable costs.
Operational Versatility Operators have detailed control over weld parameters, including programmable arc ignition and extinction intervals (0–5 seconds) for optimal crater filling. For applications requiring weave patterns, the Li’l Runner CDL features an integrated auxiliary socket to power the external OSC-8 PRO pendulum oscillator. It is the ideal answer for longitudinal seam welding in trailer manufacturing, storage tank fabrication, and shipbuilding.
