Welding carriages in the Wel-Handy Multi Series are designed for automated and stitch welding, weaving and twin-torch welding operations. The lightweight and compact carriages have a low center of gravity for continuous welding of large, steel-frame structures. A magnet provides 66 pounds of traction power, which allows the carriage to climb vertically. The units travel at 59 feet per minute. A quick-release handle allows the operator to reposition the carriage as needed. Other features include digital speed setting, high-performance trace traveling and spatter prevention.
