ArcRover 22 / FlexTrack 45 Pro — welding carriages

Technical specifications

Specifications are taken from the manufacturer’s technical documentation. Updated 11/06/2026. Customs codes are for reference only; the final code is determined at customs declaration for the specific model.

Description

The torch moves directly on the part, so the carriages work on flat and curved surfaces and in hard-to-reach places, and the welder gets less tired. ArcRover is held by a built-in permanent magnet and has four-wheel drive, so it travels on horizontal, vertical and curved surfaces. The ArcRover 15 and ArcRover 22 versions weld longitudinal seams by the MAG process in positions PA, PB, PC, PF and PG, carry up to 15 and 22 kg and reach 250 and 200 cm/min respectively. The carriage is powered by a 25.4 V lithium-ion battery or an external 230 V source, and motion and oscillation parameters are set on the onboard controller. FlexTrack 45 Pro travels on rails with a built-in magnetic holder and welds MIG/MAG and CMT in the same five positions, with 230 V supply. Options include linear and radial OSC torch oscillation and ACC automatic distance control, and the FRC-45 Basic or FRC-45 Pro remote has a digital or touch display.

How to choose

The carriage type is determined by the seam geometry. For straight longitudinal seams, including vertical ones, ArcRover is taken, with ArcRover 22 having the greater load and ArcRover 15 travelling faster. Circumferential and orbital seams of pipes and shells are welded by the FlexTrack 45 Pro on a circular rail, curved geometry on a flexible one, and straight parts on a rigid one. When parts are serial and cylindrical, stationary circumferential and longitudinal seam machines from the same manufacturer are more suitable.
