800 Series Closed Arc Weldhead
800 Series weldheads are easy-to-operate tools for autogenous tube welding. Six models (805, 810, 820, 830, 840, 860) with overlapping ranges cover tubes from 3 – 152 mm (0,125” – 6”) O.D. Magnatech’s 800 series heads make tube-to-tube and tube-to-fitting welds in less time with precision and repeatability. The double-clamping design simplifies work piece fit-up and eliminates tack welding in many cases. Collets are available for any tube and fitting size.
Digital technology forever eliminates the need for periodic weld head calibration – rotation speed remains accurate regardless of head wear and heads can be interchanged without time-consuming recalibration.
Tungsten holder allows field replacement in a minute. Virtual 360° circumferential contact of tungsten electrode guarantees positive arc starting. The 800 Series utilizes two inexpensive insert plates made of a heat/UV resistant material to protect the Head housing and mechanism. If necessary, they can be replaced in minutes.
