The argon shield is the way to go, cocking about with CO2 from the local pub is just putting another obstacle in your way of doing a half decent job. If you are going to be doing any sort of volume of welding then the conversion kits to the bigger BOC bottles makes a lot of sense. However if you are doing that level of work then a bigger bit of kit would be the way to go. From your first post it sounds like a small fan cooled (aka trubo) MIG is the way to go and the small argon shield at least until you know which way is up, so to speak.

you can get MIG’s that run with out gas as they have a flux in the wire which provides a gas, apparently they are better if you are using it outside with a wind as the gas dose not get blown away from the work. Have never used one of these gas less ones mind so the above is hear say.

All the welding would be done outside so the gasless one might be better.

If you go to a bigger machine mart they have a section at the back where they have returned goods. Some of the stuff is old and scruffy as hell but very expensive. However some of the stuff is totally unused and a good bargain.

I bought my big MIG from them - 225amp or whatever. All the was wrong with it was a bit of the plastic trim around the front had broken off - £140 off normal price!!!

I bought a decent welding torch from a proper welding supplies which makes a hell of a difference.

I agree with the gas. I have a bottle of CO2 pub gas at the moment. It does the job - just. Life is a lot easier with argoshield but it ain't easy to get.

Get a good auto welding helmet - much easier for beginners.

Chewy,

You have probably seen this forum but lots of useful info.

IIRC there is a guy that can get Clarke welders cheaper than Machinemart.

I've never had a problem MIG welding MS with Co2.
But I do get my bottles from a welding supplier not the brewery.

The No Gas sets are OK, but the fluxed wire is very expensive and not as readily available as normal wire in 0.6 or 0.8mm.

Codprawn, thats exactly where my current MIG came from, the returned goods section at the back of Machine Mart in Portsmouth. It had been used, but was hardly marked and was @60% of list price.

Don't be sucked in by the cheaper flux cored wire either-it's awful and the flux can be intermittent. You'll only get a good weld from one if it's using the most expensive stuff which makes it cheaper to buy a gas one and pay the extra.

I would look at 180A and above but pay attention to the duty cycle of a machine when comparing models. A mig may be rated for 180A but at 10% duty, ie for every minute of welding it needs 9 minutes of cooling down.

So I've got it down to 180A gas Mig so far.

Watched the videos on the other site of gas and gas less and that made my mind up.
