ZF1200 straight seam welding machine is our standard compact model for thin-wall small cylindrical workpieces, with fixed 1200mm effective welding stroke.

Light integrated cast beam saves workshop space, equipped with full segmented water cooling piano-key fixture to suppress thin plate thermal deformation.

It supports TIG/MIG/Plasma welding sources, realizes smooth single-side welding double-side forming with back argon protection, ideal for mass production of small tanks and ventilation ducts.
