which MIG welder

Looking to buy a new MIG welder, initially I will use it to weld the frame work for my new workshop roof which is 6mm angle iron. Following that I will use it for car bodywork panels. Looking at web sites it says that cheap MIG's are difficult to use and it shows in the quality of weld, also 150 - 180amps is preferable. Any advice or experiences very welcome, thank you.

I've got a Sealey SuperMig 185 which can handle that thickness, but I've never tried it with thin stuff. I'd guess the flexibility is the hard thing to find with more powerful welders, ie do they 'turn down' low enough to do thin stuff...

It depends on your budget, you get what you pay for. If I was looking at get a new 180 amp mig I would seriously consider a Portamig although for 6 mm you might be better of with an arc welder (MMA) Again check the mig welding forum

Something like my old Migatronic Automig 180 would be ideal for what you want. Cheap(er) machines won't handle the power for 6mm in one clean pass AND turn down low enough for thin car panels. Mine's rated at 25-180A IIRC. I think I paid £250-300 for mine a while back, but they're hard to find second hand as no-one wants to part with them!

Failing that, something new and shiny from the reputable traders on the mig welding forum would be a good first step.

I was thinking a smallish mig for the bodywork, and a cheap arc welder for the 6mm stuff.

Depends on budget of course, but one that will do all you ask will be a very decent machine.....

Agree the mig forum is the place to go.

I've got one of these:

Does car panels OK, may struggle a bit on the thick stuff but a V-groove and two passes would sort it.

I had a 150te, perfect for car panels and up to 3-4mm, when it failed to get enough heat into the work on 6mm, it looked okay but when cut little penetration.

Powerful MiGs have greatly reduced in price these days, however if I was going to send £400-£500 it would be on a reputable DC TIG set

I've got a portamig 185 from weldequipe.

It does it all, chassis building, car body repairs the lot.

I have the R-tech 160A MIG and can highly recommend it (though I don't think their current model is 160A anymore, think it might be more?). It 'feels' every bit as good to use as the industrial machines I have used in the past. Can be wound right down to do a good job on car bodywork.

I would avoid the cheapy clarke/saeley offerings aimed at the DIY hobbyist.... The wire feed mechanisms are totally garbage. I had the 151te for a while and it was terrible! Yes you could stick bits of metal together but even penetration and "neatness" left a lot to be desired!


Bought a second hand cebora for £300... What a cracking machine it is!!!

as stated you get exactly what you pay for

cheap sets use aluminium for transformer windings not copper with small undersize cores , and without a physics lesson not a good idea for weld quality and smoothness.

cebora are reasonable they make all the snap on weld sets ( or used to ) , not the best but a good compromise .

go to a proper welding set seller industrial they can advise .

a good inverter set is easy to weld with but expensive , usually more powerful than a transformer set due to less losses

unfortunately to sum up you generally get what you pay for in a welder .
