I'm going to look at a welder today (Kemppi Kempomat 2500) and if I bring it back I will have my first mig welder. I have a few beginner questions... 1. How important is the mig torch? It has a euro connector and some unknown brand mig torch I might be able to determine what torch it is when I can inspect it myself. But it's not a Kemppi original. I will likely use the existing torch for a good long while yet but I am curious anyway. Kemppi torches seem to be about 1.5 - 2x the cost of Binzel torches from what I can see. Are they worth the extra money? Are there any particular issues one should consider when looking at torches? 2. How big a spool should one get? The welder can take a 15kg spool, but I have some vauge memory of having read that if you are a hobby welder and don't use that much mig wire, then it can get rusty with time, so it was better to buy 5kg spools that would be used up faster. Anyone care to chime in on that? 3. I have no MAG gas, not even pure co2. This purchase will clean me out a bit so I can't be buying a proper gas bottle for a while. I was wondering if I should buy a spool of gasless mig wire so I can at least use the machine, or try and run with pure CO2, I think I could scrounge up some smaller CO2 bottles for a lot less money. Any other things to consider?
