GTH 1002

The welding rectifier (thyristor-controlled) with constant voltage characteristics for submerged-arc welding up to 1000A in combination with the pre-adjustment of nominal values on the welding automats of the KA series. Thus especially suited for mechanised, semi-automated and automated welding processes (also with optional interface for external control) 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.
