Universal Double Head Welding Machine

High precision machine which, in a single work cycle, allows the simultaneous welding of 90° angles and “T”, cross or “H” transoms (in any combination between them) as well as variable angle welding between 35° and 180°.

The unit also allows the simultaneous welding of the two ends of a transom by the 90° rotation of each of the two heads.

5 Reasons to choose the SL2 UNI

Ideal for welding transoms with "T", Cross and "H" shapes.

Possibility to carry out multiple combined weldings at the same time.

Wide variability of weldable angle: Between 35° and 180°.

Automatic adjustment of the reference stop of the transom counter-piece.

Quick replacement system for welding countershims.
