Guys, I have a small engineering business and from time to time I need to weld, typically 3mm-8mm stuff. I used to manage fine with an old Oxford oil filled stick set I had, it packed in one day so I bought myself a Sealey 140 Supermig to replace it. Being new to MIG welding it never gave me the same results as the stick machine and I put that down to me. Ive had the machine about 4yrs now and although Ive got better with it its never been as nice as I might have hoped for. I like these smooth runs that I see others getting and it just doesnt seem to happen for me. I feel as though the arc isn't as stable as the old stick machine was, its seems to jump about a bit and some days the MIG seems to weld better than others. Im starting to wonder if these mixed results could be more down to the quality of the machine than my skill? I accept the machine I have is a cheap hobby level MIG and if I thought spending a few quid on a decent machine would give me better results I would. Problem I have is knowing if its me or the machine, any thoughts? This is about my ability level to give you some idea of where Im at.
