Is there a way to limit or manage inrush current when something big is turned on?
I ask, because I have a 3 phase transformer tig, and my supply is current limited to 25amp/phase 380v. 1 time say in 3 I turn the set on, and it throws the supply breaker, but once it gets the transformer energised and the fans span up etc, I can happily weld with it on the lower ranges for as long as it takes. Trouble is, if I use the pedal and pedal off and back on, it does it then again when the contactor comes back in, so I'm constantly playing the trip out lottery when I'm using it on tig pedal for thicker ally etc. Its really distracting and I'm finding it hard going to improve my tig as I spend most time walking to reset the breaker in the main panel.
So is there some sort of huge industrial capacitor or something I can use to buffer the supply from seeing this huge initial spike?
I cant change the main supply trip it takes out as its covered with tamper seals etc...
