Orbital Weld Heads for Fusion and Wire Feed welding of pipe

Magnatech Redheads are designed to make ipe-to-pipe and pipe-to-fitting wleds with precision and repeatability. Redheads can be used for fusion welding, or with filler wire addition - an integrated head-mounted feeder is standard on all models. Three models cover the size range of 12.7 to 168 mm (0.5 to 6.625") OD. Digital technology forever eliminates the need for periodic calibration - rotation and wire speed remain accurate regardless of the wear, and the heads can be interchanged without time-consuming recalibration.
