REDHEAD WELD HEADS

Orbital Weld Heads for Fusion and Wire Feed Welding of Pipe

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

TORCH ROTATION
Uniform torch rotation is ensured
by a chain and sprocket drive using
a precision stainless steel bearing
assembly that is immune to heat.
