pulsed arc parameters

By jeff777 Date 02-25-2009 19:40

Hello, I am welding pulsed mig with .052 wire and 90Ar 10CO2 and I need to achieve some specific weld requirements. The best way to do that would be raising the peak voltage up to 52 Volts for 700ipm. My Question is what the consequences would be of such a high peack voltage during high level of production? Has anyone heard of 52 V peak voltage for pulsed arc parameters?
Thanks
Jeff

Welcome to the forum

Yes
Current and Voltage peaks can be very high with some GMAWP programs. Some of the newer GMAWP programs are balencing more than 16 electrical variables in both constant current and constant voltage, in a sequence of several thousand times per second.. So those high spikes are controlled at very short dwell times.

Before any specific advice can be offered you are going to need to tell us a few things

Alloy (the 90/10 suggests steel but it's best to ask)
Material thickness?
Position and joint configuration? (Flat fillets? overhead?)
Weld size and contour?
Travel speed?
Weld power supply (Brand, age, pulser options etc)
