The Kjellberg KA 2-UP was developed for the installation to guiding systems, i.e. welding gantries and column and booms. The submerged-arc welding head is available as single wire and parallel wire version for wire diameters of up to 5 mm. The SA welding heads are part of the modular principle of the KA series and can be individually and easily adapted to any welding task. The pre-selection of nominal values for welding current, arc voltage and speed in coordination with the respective power source ensures a high degree of automation. The KA 2 welding head has an automatic ignition and automatic burn-free function for an optimised welding process. The start-up phase and end crater filling phase can be adjusted separately. All KA welding heads are equipped with a laser pointer for visual seam tracking. Via a cross support, the KA 2 can be manually positioned with an effective adjusting range of 100 mm each.
