Save for the bottle of C25, the MIG conversion on the Lincoln is complete. I spent fifteen bucks on fittings. The initial purchase of the bottle and C25 is going to be over $200. After that, it will just be done on exchange.
Mrs. C was a bit miffed about the upfront cost of the bottle but I mentioned that I'd now be able to do those artsy fartsy projects she keeps on about. I have no plans to actually do them but that how I sold it.
