Page 14: Memory Organisation
Operating Instructions PA-xxP 3.4.4 Memory Organisation 3.4.4.1 Memory Locations (Profiles) The PAxxP has 99 memory locations each of which is able to store the complete details of either a single or double pulse weld profile. In order to identify the memories, each location is given a number between 1 and 99. -
Page 15: Limit Functions
Operating Instructions PA-xxP Limit Functions 3.5.1 Monitored Limit Parameters The PAxxP controls the weld current output. Since V=IxR (Ohms Law), as the arc resistance changes, the voltage will reflect this change. Hence the PAxxP measures this voltage parameter in real time as the weld occurs, thereby allowing the machine to react to unexpected weld conditions. -

9. If the problem is still present after performing all of the tests above, it could be that the internal fuse has blown. If it is suspected that this is the fault with the unit, please contact Amada Weld Tech for assistance, as it may be necessary to return the unit for repair. 961-00035 rev11... - Page 41 Operating Instructions PA-xxP If the timing of the external signals (weld trigger inputs) is too fast, then the welder will stop operating. All of the external fault signals are energised, and no inputs are recognised. The welder will start sounding its beeper on and off. To recover, power cycle the unit, and check the timing of the external PLC signals.
