Drawn arc welder PRO-D 2200

mobile

The microprocessor controlled stud welding unit PRO-D 2200 is designed for stud welding with ceramic ferrule or shielding gas and short cycle stud welding with or without shielding gas. Microprocessor control, continuous adjustment of welding current and time as well as constant current regulation ensure in connection with the high performance of the unit optimum welding results and repeatability. The unit is easily operated by the very robust rotating pressure switch, all functions and parameters are shown on a big display. Pre-installed welding programms facilitate the choice of the right adjustment values for different welding tasks. Additionally, user specific welding programms can be stored. The modular design of the unit allows the customer specific choice of the equipment features. All optional equipment features can be retrofitted. The welding parameter monitoring, integrated as standard in all series PRO-D stud welding units, enables a quality control of the finished welds. The unit can detect each discrepancy from the ideally permitted values. So the welding supervisor and the operator can immediately recognise deficits in the welding operation like insufficient balancing of blowout effects, tilt of the welding gun etc. Consequently, the production control can be reduced to monitoring and recording of all welds by the unit and a subsequent visual inspection. By default, the parameter sets of the last ten welds are stored. The optional available welding parameter memory allows the storage of 24500 welds and has an USB-interface for data transmission to a PC.
