TOA230 Open Type Orbital Weld Head

TOA230 is one model of TOA series Open Type Weld Heads. It covers a pipe OD range from 120mm - 230mm.

​

The Open Type welding heads were conceived as a tool for orbital TIG welding with or without filler wire. TOA series weld heads have AVC/OSC function and are often used on thick-wall (3mm - 16mm) pipe to pipe/elbow/flange welding. The diameter of the tubes to be welded covers a range from 64 mm up to 180 mm.

Open welding heads are equipped with a TIG-torch with gas diffuser. Sufficient gas protection is achieved only at a zone around the torch which is covered by the shielding gas streaming out of the gas lens. During the welding process, the arc can be watched and controlled directly by the operator.
