A-6 INST ALLA TION POWER WAVE AC/DC A-6 ELECTRODE AND WORK CABLE CONNECTIONS Due to the PowerWave AC/DC ’ s ability to produce either a DC positive, DC negative or AC output the electrode and work connections do not need to be reversed for the different polarities. Additionally no DIP switch changes are required to switch between the different po[...]

VOL T AGE SENSING The best arc performance occurs when the PowerWave AC/DC has accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work lead cables can influ- ence the voltage apparent at the studs of the welder. Voltage sense leads improve the accuracy of the arc conditions and can have a dramati[...]

CONTROL CABLE CONNECTIONS BETWEEN POWER SOURCE AND WIREFEEDER Connect the control cable between the power source and wire feeder. The wire feeder connection on the PowerWave AC/DC is located under the spring loaded output cover, on the case front. The control cable is keyed and polarized to prevent improper connect. For convenience, the control cab[...]

EXTERNAL I/O CONNECTOR The Power Wave is equipped with a terminal strip for making simple input signal connections. The terminal strip is located underneath the spring-loaded cover. It is divided into three groups: Trigger group, Cold Inch Group and Shutdown Group. Because the Power Wave is a ‘ slave ’ on the DeviceNet network, the Trigger and [...]

B-7 OPERA TION B-7 CV WELDING Synergic CV: For each wire feed speed, a corresponding voltage is preprogrammed into the machine through special soft- ware at the factory. The nominal preprogrammed volt- age is the best average voltage for a given wire feed speed, but may be adjusted to preference. With syner- gic programs, when the wire feed speed c[...]

B-8 OPERA TION B-8 PULSE WELDING Pulse welding procedures are set by controlling an overall "arc length" variable. When pulse welding, the arc voltage is highly dependent upon the waveform. The peak current, back ground current, rise time, fall time and pulse frequency all affect the voltage. The exact voltage for a given wire feed speed [...]
