Advice on buying mig welder?

Question

I need some advice on which mig welder to buy. Im a complete novice and only need a fairly cheapo one to do a bit of welding on my truck chassis before it goes off to be blasted and powder coated. its only a small amount that needs doing, so i dont need anything heavy duty. Im thinking of spending around 150 quid and have found a few but im not sure which to get. Could anyone with any knowledge have a look and recommend one.

cheers

Answer 1

I have got the last one which gives very good results.If you buy a gas one use argon mix and not the co2 which comes with it for a better weld

Answer 2

I don't think you're going to like my answer. I had the loan of a mig welder for some time, and tried to weld with it - test pieces only - and never managed very satisfactorily work. Much better with gas (oxyacet) but the bottle hire and filling was way to expensive. For the cost of your welder you would get an awful lot of professional welding done, and there's a steep learning curve to getting good welds.

Answer 3

For professional welding we use the inert gas type but for a light duty just go with flux core and save the extra expense in my opinion.

Answer 4

If welding on the chassis, you will choose one that can weld up the thickness of what you need to weld.

Answer 5

If you are welding a truck chassis you will need a fairly high output one for a good solid weld.  If you want it to be new, Machinemart are a safe place to shop (most of their welders are Sealey clones but cheaper).  You might consider using the same amount that you are budgeting for to buy a better quality s/h one. if you buy well you should get all your money back on resale and maybe even a little profit.
