phase converters

How does one figure out which one to buy?  Have esab 875  Anyone else ever heard of this problem and/or what would be the solution?
Reply:Which 875 do you have? Looks like some are 230v 1 or 3 phase,some 460 volt 3 phase, some 50 hz, etc.  Didn’t see any 230v.60hz 3 phase.Miller a/c-d/c Thunderbolt XLMillermatic 180 Purox O/ASmith Littletorch O/AHobart Champion Elite

Reply:The stick and tig take a large converter. Mig welder takes a smaller size.I build mine it can be simple as using a single phase motor 3/4hp and a [three phase motor star wound 5hp] at same rpm. This will run very large welderDave Originally Posted by HarryvanHow does one figure out which one to buy?  Have esab 875  Anyone else ever heard of this problem and/or what would be the solution?

Reply:If your machine needs 50Hz, thats not something that a typical phase converter will be able to give you if it is operating off of 60Hz "power".  It wont change the frequency of the input voltage waveform. 1st on WeldingWeb to have a scrolling sig!

Reply:In America it is 60Hz.I have only seen equipment that was both 50Hz and 60Hz.

Reply:Yes I'm aware of that.  The OP mentioned 50Hz input, hence my post clarifying the difference. 1st on WeldingWeb to have a scrolling sig! HTP Invertig 400HTP Invertig 221HTP ProPulse 300HTP ProPulse 200 x2HTP ProPulse 220MTSHTP Inverarc 200TLP HTP Microcut 875SC
