    Or add corn-flower to your petrol to thicken it up a bit.

    That also means not enough gas or a contaminated weld.

    You can MIG a tank but you have to know what your doing and be good at it, MIG welded the tank on my T 10 years ago and its never leaked. Much easier to gas weld or TIG though.

    The problem with mig is that every time you stop a weld it leaves a small central hole and it will leak. When we used to repair them they were always solder sweated repairs. We didn't use weld as it caused instant corrosion inside the tank plus lots of distortion.

    Tig is best for a tank but if you use mig then you need to solder sweat the finished welds to make sure it doesn't leak.
