a question about a suitable process

[Jammy James]

I have been thinking about what is the best process for aluminuim welding bearing in mind i would rather spend money on a mig as i can weld steel easier as well i have looked on the rtech website and found this mig welder http://www.r-techwelding.co.uk/Mig_Welder/240V_Mig_Welders/MIG_Welder_R-Tech_I-Mig200 it says it is ok for alli welding as well. I only want to weld very small amounts of alli a year probably the equivilent of a meter of weld or i have fond this ac/dc tig but would rather spend money on a mig but would splash out on a tig if needed http://www.r-techwelding.co.uk/welding_equipment/Tig_Welder/Tig_Welder_R-Tech_Tig201

any mig can do ali with the right wire, gas, liner and tips

Buy the MIG welder, and get some-one else to do the TIG when you need it.

How well does a mig weld ali compared with a tig

What sort of ally things do you intend to be welding?

That mig looks half decent, get yourself the relevant liner and rollers for ally and that ought to be adequate for your low use ally needs. However, with the cost of rollers and liner, along with consumables, i almost wonder if it would be easier and cheaper to get your ally welding done for you.

not as pritty at times but with a decent set up and user perfectly good. many people use a spoll gun to stop the wire kinking up in the feed

Horses for courses. We use the mig to weld up light-weight frames quickly; tig to get a watertight controlled weld on (dip-mould) tooling.

Hitch i will be welding sheet such as chequer plate on cars, the welds will be hidden
ok thanks guys you have just saved me and my dad some money as a "so called friend" told us it is impossible to weld alli with a mig

 

[madkayaker]

i had a bit of a go with a clarke 90 and got some good looking welds out of it before it went bang (not on ali but to thick steel)

in the tutorial bit there a bit on ali mig welding

ok thanks for the advice on looking at the tutorial section Madkayaker
