GTH 1202

The welding rectifier (thyristor-controlled) with constant voltage characteristics up to 1,400 A is especially suited for semi-mechanised 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 and other areas. 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.

EXTRA: Time-limited standby operation of the GTH 1202 reduces power consumption as well as noise and pollution of the machine.
