Lorch Trac Wheel Pro is a portable and programmable welding carriage for extra challenging longitudinal and curved welding seams, both horizontally and vertically. Always when it comes
to stich welding and welding seams with larger dimensions, Lorch Trac Wheel Pro is the right choice.
Typical application areas are long metal structures such as trailer manufacturing and rail vehicles, shipyards and large tanks such as truck, oil and water storage tanks.

Features and Bene ts
▪ 4-wheel-drive with magnetic xation and active control for stable welding speed in all welding positions
▪ Constant and reproducible speed control facilitates consistent quality of welds
▪ Easy and exible 3D torch adjustment allows optimal torch position
▪ Concave and convex curved welding seams for large tanks possible
▪ Comprehensive accessories for welding with two torches and a wide range of di erent seam geometries
▪ Easy connection with Lorch welding inverter via Lorch Plug&Weld
▪ Welder friendly programming and storage of up to 40 welding and oscillation programs
▪ Free adjustment of parameters such as total weld length, weld length, distance between welds
and other allows exible de nition of welding sequence
▪ Increased travel speed inbetween welds saves time
▪ Reproducing the exact weld seam geometry avoids seam oversizing and reduces consumption of ller material
▪ The optional upgrade with the radial oscillator is great to produce weave welds and compensate positioning deviations of the workpieces
