Hi Mac; We are having a similar problem at our metal shop with two stacked SW4024s. They are stacked so that inverter #2 idles until something 240V is turned on -- well pump and welder are the only 240 VAC loads. We are getting an overcurrent error and shutdown by just turning the welder's power switch on -- NOT when starting to weld.
Any help from the list appreciated! -- Dan Fink, Executive Director; Otherpower Buckville Energy Consulting Buckville Publications LLC NABCEP / IREC accredited Continuing Education Providers 970.672.4342 (voicemail) On Thu, Mar 29, 2012 at 8:25 AM, mac Lewis <maclew...@gmail.com> wrote: > Hello wrenches, > > I have a customer that I have been working with over the phone.
