Longitudinal Seam Welder

Longitudinal welders generally have a longer machine throat as compared to Transversal welders. Longitudinal seam welding welds the part in the direction in and out of the throat of the machine.
Dahching offers Fixed Throat length and Adjustable Throat Length machine, see UNIVERSAL seam welder.
Weld speed from 0.9 meters to 2 meters per minute

Lower welding arms are designed as per weld part design.
Wheel sizes are part dependent
