Li’l Runner CDL Cordless Welding Tractor

PRICE

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.

Description

  • Conveniently powered by an 18-volt DC battery, the same battery as used in other cordless Steelmax machines
  • LiHD battery ensures extended power availability even for the whole shift
  • Intelligent battery management for a long-lasting battery
  • Digital speed control and stabilization for repeatable high-quality welds
  • Multifunctional LED display to present travel speed, units, and diagnostic messages
  • Compact, lightweight design with durable aluminum cast housing
  • Possibility of pre-setting the torch activation time before and after the tractor travel for better filling of the weld seam at both ends
  • Built-in oscillator socket for direct powering of the external OSC-8 PRO pendulum oscillator
