GTH 802

The welding rectifier (thyristor-controlled) with constant voltage characteristics up to 800A is especially suited for submerged-arc welding. Mechanised, semi-automated and automated welding processes in combination with the pre-adjustment of nominal values on the welding automats of the KA series (also with optional interface for external control) are available for the toughest use in tank facility and boiler construction, bridge construction, shipbuilding and industrial mounting. All Kjellberg power sources are charcterised by a reliable ignition behaviour and a stable arc. Big analogue displays make it easier to monitor the entire welding process.
