[MW:22426] Heat input in GTAW- P- HW

Hello, with pulsed you should use only peak amperage if you weld under asme IX requirements only, then only max HI isan essential variable. As you cannot measure peak value only (because of the pulse) with an arc logger or a clamp ampmeter set peak value on generator should be considered (not the one for hot wire). If you want to measure the amperage then this is more an average value that you measure rather than a maximum and the WPS should indicates it you consider measurement in production rather than max set value.

Regards,
Rėmi
