syncrowave 250?

admin

which is a better machine the 250 or the 350, what should I look for when buying one other than welding on it to make sure it works, how easy are they to repair, how often do they breakdown and are parts still available for them? somebody on the forum stated that the syncrowaves are inverters. a fabrication guy told me to get a transformer rather than an inverter. what do you guys think?

Reply:I have a lot of welding experience; I'm just wondering from machine to machine how they differ. I know a 250 will weld thinner material, but how thick will it weld?also, how thin will a 350 weld? I don't like Lincoln; I always have to scratch start on the Lincoln machines I've used. that being said I want to stay with miller. what do you guys recommend as far as a tig/stick machine that does both ac and dc? i would like to have a water cooler capability.Last edited by miller#1; 9 Hours Ago at 06:40 PM.

Reply:inverters manipulate the electrical current to create ac or dc, I can't remember which comes first. whereas a transformer is sort of organic.won't be doing any portable welding at least not for a few years therefore don't really need the portability of an inverter. I thought syncrowaves were transformers, but somebody on this forum just told me that syncrowaves are inverters?i want to be able to weld exotic metals like titanium, Inconel, nickel, copper, silver and gold. along with the basic stuff like stainless, mild steel, aluminum and cast iron.
Reply:John T, thanks for the help I appreciate it!true wisdom only comes from pain- I've never heard anything truer. I mean that truthfullyLast edited by miller#1; 5 Hours Ago at 09:55 PM.
Reply:The 250 and the 350 weld about the same. Both are transformers, and neither are easy to repair if the main PC board fails. Board repair or a new board is between $600 and $900.The thing that would sway me one way or another is a pulser and or sequencer. If the 350 has the pulser or sequencer installed, I would go for that machine.
Reply:I'm picturing the old tall syncrowave 350s with a handle that you turn to switch polarity not the new ones on millers Websight. are we talking about the same welder? I used an aerowave in class for about 3 years. I would jump back and forth between my booth with the aerowave and the taller syncrowaves. had a syncrowave 200 but no other machine I've welded with even comes close to comparing to an aerowave. most of my experience is in tig welding. i want an aerowave realistically but they dont seem to be easy to find.Last edited by miller#1; 5 Hours Ago at 10:27 PM.
