I've been doing a little flux core welding lately. My welding skills are horrible, but my angle grinding skills are progressing quite nicely! The flux core is a bit of a pain for a number of reasons so I see giving MIG a try in the future. The problem is the shielding gas. More specifically, how to get it affordably for a hobby welder. Last time I checked, Liquid Air would lease a cylinder and would only fill thir own thereby limiting my options. So my question is, if any if you are using a shielding gas for welding, do you have any advice? Thanks in advance!
