Hi,

As with some HF inverters that can be hacked to be wired as effectively 1 inverter combining
the output, is it possible to sync the outputs of 2 low frequency inverters? I have a very basic understanding, but I wonder if you power 1 inverter first which will energize the toroidal transformer of the other, will it then be synced when turned on also...?
If this has been asked before, my apologies, but I have read the other posts about LF inverters and can't find much on the topic.

I have a 10kw HF WZRELB which is useless at starting an arc on my welder/3-phase drop steel drop saw. My previous inverter was a Nomad Mobile 6kw and that was better but would trip out from overload occasionally.

I bought a 5kw UPS low frequency inverter which should do nicely, but when welding for an hour straight I don't want to burn it up. Trying to do it all on the cheap and feel like I'm spending more...

Cheers,
Kyle
