The PWU 400 ACDC was specifically designed for the requirements of multilayer composite pipes. The highly dynamic, water cooled power unit is housed inside an air conditioned cabinet. The dust free and dry air provides an ideal operating environment and guarantees high reliability. The generously-sized AC power unit keeps large power reserves to accommodate the continuously increasing demands of the manufacturing industry.
The intuitive user interface displays all important welding parameters on a touch screen monitor.
Different curve shapes and symmetries can be adapted on the time and current axis to optimize the welding process for various aluminum alloys (like aluminum alloy 1050/1200/3003/3103/8006/8011) which are utilized in the multilayer composite pipe industry. The gas controller and gas mixer values are all adjustable and can be stored in a database. To facilitate the work of the operator, parameters can be adjusted depending on the processing speed.
AC-frequencies of up to 1000Hz focus and center the welding arc. The constant voltage combined with limit monitoring significantly increase the processing window and provide the necessary stability and security for the process.
