Narrow Gap Multi (HNG)

Designed for both Single (AC or DC) and Tandem (DC/ AC or AC/AC) wire welding in parallel or almost parallel joints, ranging in width from 18 mm and in depth down to 350 mm.

The HNG Multi meets the demands for a fully automatic welding process with accurate controlling of all parameters for reduced welding times and perfect weld metal when welding high-tensile material. HNG Multi is suitable for continuous operation under heavy conditions -with preheated welding objects still maintaining the same high precision and wear characteristics.
