RBK Weld Heads

The RBK 16 can be used to weld tube to tube sheet joints with inside and outside fillets with flush fitted, recessed and protruding tubes. It can be used for welding inside diameters from 10mm to 78mm. The optional wire feed unit is integrated in the weld head.

Package includes: Weld Head Three point support (support ring optional)

The RBK 20 has the same tube size capability as the RBK 16 (ID 10mm to 78mm). However, the arc gap adjustment is a simpler construction and the wire feed unit is fixed (does not rotate with the torch).
