little confused now, the ones i linked are they synergic migs? or is that an option on the inverter migs? Its an option on invertor based MIGS - if you can find one within your budget then it's worth doing - if not just stick to an invertor based unit but has most contributors to the thread have stated purchase a good quality / known brand with a good warranty not just some cheap unknown / unheard of brand has the support for these type of units will be very sparse

I think you have just not heard of, the RD welders look good, they are dealers for the parts too and i know someone as said that has one and rates it well. £500 on a welder that i wont use often, really?

well i do have a project its a 1986 mini! i was welding on it today actually, put new inner / outer sill / floor in on it. Now i was welding away and thinking what is the difference between the inverter welder and mine. Just the way it makes power . My brain had a fart, and next thing i had the welder apart, took out the heavy transformer, all the old stuff, just leaving the little main board, and the wire feeder. Then i took an inverter arc welder i had, basically bolted it into the casing, connected to the relay board, and now i have an inverter welder. The only part i havnt figured out yet is the wire feed needs power, and I'm not sure how its done, 2 wires went to what i think was a rectifier, so i need to connect those.
So i pull the trigger now, no wire feed but it makes the arc. I am still betting on buying the RD welder, but i thought id give it a go, and it may pay off yet!
Ill post some pics in a bit.

just need to know how to wire the 2 wires that go on the rectifier, not sure what to do there, jsut asked on a mig welding forum. It maybe rubbish, but it may work yet!

just so everyone knows LOL!
got the wire feed running, it arced up, did a little bit and blew the relay. So as i thought ive just ordered a new mig. Gone for the RD one, see what its like, and ill post on here .

Got me RD welder, and used it today. I ran it with old 0.6 wire i had, and c02 gas.
The welder its self is bigger than i thought it was, but not the end of the world. with 0,6mm wire with a 4m torch, the wire seems to spiral out at times as it gets bent around in the liner, but it could also be as the wire exploded when i was messing with the wire feeder, so, could be where i wound it back on.
Door of the wire feeder, its not good, but the rest of the welder is really good, very impressed.
Welding wise, almost every weld, gave the old bacon and eggs noise. Filling gaps is the biggest difference between the new and the old, it is quite easy to get your weld in with out it burning back thin edges, the old was some times a bit of a pain on that. Defo will go down as low as i need anyway on a mini.
If i had got near the end of my build and the old welder had packed up, and i had then bought this one, id be so gutted, these inverter types really are good.
So for £233, delivered, so far an absolute bargain.

It'll be even better on Argon mix rather than CO2

I don't know how much better it could get! it welds mint!
We use argashield at work, the half size but full amount air products ones, i may take teh welder into work and try it to see, but atm, £ for weld, c02 is more than good enough.

I bought my first MIG welder nearly thirty years ago when I worked in a bar, and got CO2 cylinders free. Buying another regulator and renting an Argoshield cylinder was worth every penny extra that it cost. That hasn't changed.

I will see if i can find my notes from when i was at collage, it said along the lines of c02 good for mig welding up to 3mm, gives slightly higher weld bead.
Argashield light, think was good up to 3mm also, but maybe slightly thicker, gives slightly flatter weld bead.
thicker material like 8mm you need heavy, has different trace elements in it.
I put £ for weld not as in its cheap and gives less of a weld, put as in your welding is just as right and but it is cheaper.

CO2 is the cheapest option but not ideal for sheet steel. It's better suited to thick steel as it gives a deeper penetration 😁. So more chance of blowing holes 😁😁. It also gives a less attractive bead- more grinding😁😁😁, and more splatter - still more grinding😁😁😁😁.
Sorry 😐

i remember about the spatter bit, but honestly there is next to nothing on my welds!
I know what a good weld is like, i work as a fabricator/fitter for a tipper company, do lots of welding, been doing it for 18 or so years now, not just saying it, ive a fair idea on welding. I really rate the c02, if i remember tomorrow ill do some welding samples and post some pics.
I was thinking that, when people say c02 is rubbish, they don't recognise say when it is going to drop threw, i either do short runs, or pulse [fart fart fart ] welding on really thin stuff. On thick stuff at work we put a weave into the weld, [not sideways, forward and slightly back] which is fine for cosmetic welding, but when it comes to a tow bar or welding a ram bracket in, out comes the smooth movement, text book welding.
I also will taek teh welder into wrok and try it on " real " gas...
thanks.

I have always used an argon mix and get great results with my Invertor based MIG - has stated previously there are loads of people out there that will balk at the price of a invertor based MIG has they just compare them directly with a cheap transformer based MIG which in comparison are pure rubbish - The invertor based units are getting far more affordable too - give it a few more years and transformer based MIGs will only be found in two places - The Science Museum & skips

I bought the Uptime Mig over 6 months ago .. I've been using it regularly with gas for short car welds.. It's a great IGBT Mig!.. I can't comment on it's long term reliability yet! .. But it's well built, as good as any other light use IGBT I've seen.. Nice metal wire drive, good controls including inductance, however, there's no guidance on the best settings.. but if you have an ear, for a good mig setting, It's easy to get a solid clean weld! However with nochless knobs, remembering the settings is hard at first! .. The main problem is the manual, it's basic, very basic! .. I'm not a supporter of the Western Brand Ideal.. Everything comes from China anyway! .. I do know that this machine will possibly to collapse, the day after it's one year warranty! But at only a £140? .. I'd probably buy another! (It's actually an Aberdeen based dealer) I guess.. the only thing i'd like, which this doesn't have, is a Spool Gun power outlet, which the R-tech has.... but how much more would I pay for that?

that looks a good set, probably mine is no better but i have the 4m euro tourch, that now means i can weld anywhere on the mini with out moving the mig set. nochless knobs, the pro ones we have at work don't either.
i would say though the old murex welders are still the best.

Those who sell transformer migs claim better reliability, is there really much in it?

They will claim anything in order to sell their machines - basically what they stating is that new welding technology is unreliable which is rubbish - I have yet to hear of anyone having any real issues with a invertor based MIG - mine works hard for a living and takes everything that I throw at it - you will also find lengthy guarantees offered on all the decent branded invertor MIG's
