The main frame of these seam welders is of heavy, rigidly reinforced welded steel construction for a minimum of mechanical deflection but a maximum of accessibility and neat appearance. The lower conductor support or knee is a heavy steel fabrication keyed to the frame for accurate vertical adjustment. The upper conductor is insulated from the frame, while the lower conductor is grounded to the frame, therefore work support tables or conveyors can also be grounded.
In addition, we stock a complete inventory of replacement parts and in-stock components can be shipped within 24 hours of order receipt. When you buy from Taylor-Winfield, you get sound technical advice, competent service and continued performance backed by single source responsibility.

Circular - wheels are perpendicular to the welder throat and are the most popular for making long seams in flat sheet or around flanges, as in fuel tanks or around a cylinder.
Longitudinal - wheels are parallel to the welder throat and the lower conductor is usually an unsupported round horn which allows clearance in welding the longitudinal seam of a cylinder or barrel.
Universal - Capable of conversion to either circular or longitudinal rotating the upper weld head and replacing the lower arm. Two lower arms would be provided
