I bought a Sealey Supermig 185 back in the mid 90s. At £500 it was at the very top of my budget then, as a semi-pro machine. Over the years I upgraded it with a euro torch and a heavier earth cable and it gave good and dependable service. It was a big and bulky piece of kit that took a disproportionate amount of space to store because you couldn’t lift it up on top of anything else, nor could you really store anything on/above it. A similar spec machine today is still around the same amount of money, making it half the price or less in real terms. However, I wouldn’t choose a transformer machine now, not with the capabilities of modern inverter kit.
This year a modest inheritance left me with a few pennies spare to misbehave with and I treated myself to a Kemppi Minarcmig Evo 200. I have been welding for over thirty five years, and did my training with the MoD in the mid 1980s in an environment where budget wasn’t a consideration, so I’ve been fortunate to have used some pretty impressive kit. However, I can honestly say that I have never used anything as good as this. It’s an utterly awesome piece of equipment. With the right liner, tips and gas it will also weld aluminium, or CuSi “MIG brazing”.
