    I was wondering if anyone can give me some advice.
    I would like to try flux core welding and was wondering if pure argon is the best to use, or is using a gas all that necessary ?
    Secondly, will flux core wire say 0.9mm run ok in a standard wire liner or do I need to change the liner ?
    Cheers chris

    Flux cored wire doesn't require gas, that's the whole point of it, although no doubt there will be some special occasions where it does :dontknow:

    The liner should be OK, but if you can't get a 0.9mm nozzle, then go one size up to a 1mm (or drill a 0.8mm one out)

    I'm using flux core atm and the 0.9 wire fits in the existing 0.8 tip just fine. Although you can get 0.9 tips for a variety of MIG guns on Ebay if required.

    I know that you asked about flux core wire, but there is also Dual shield wire requires gas as well as the flux inside the wire wire. just for your information,

    If you’re using a dual shield wire, where you have the flux you would also need gas. The one we use is Argon 80% CO2 20%, at BOC it’s called Specshield,but you could also use the argoshield gases (heavy, light and universal)

    If you are going to use no-gas flux core wire, you have to change the polarity of torch & ground.
