Gas or gassless

[Hippo]

I have been using a mig welder for twenty years using Argoshield gas. However, it costs me app. £40 per half year to rent the bottles from British Oxygen.
Because I now only use the welder occasionally, this is a very expensive option and so I am contemplating a gassless mig. My question is: Is there any appreciable difference between gas and gassless welding? Also, are there any reccommended machines to use for car body repairs?

Yes, a huge difference. It's worth doing a search and reading up about the topic on here. It is covered often. £40 rent for 6 months is expensive.

Thanks for your reply.

The reason that I stopped using pub gas was that I was told that it had been deliberately contaminated to prevent people using it for welding.

(I supposed that this was because breweries were fed up with losing their cylinders.)

I there any truth in this?....I still have two cylinders.

Nope

two types of "pub gas" one is co2 the other a co2 and nitrogen mix

the co2 is still ok to weld

Rubbish, the truth is that other gases (Nitrogen) are required for the pub trade, not just CO2.

Does anyone out there know any suppliers in Black Country/Staffs/B'ham area that will fill up brewery bottles with CO2 for reasonable cost?
