IIRC, back about 10+ years ago, I had a Lincoln MIG welder I bought at HD and I thought the Argon CO2 starter tanks used to cost around $70-80 and refills were $30-40. I sold it a few years later during a move.
Fast forward to today. I purchased a HF combo MIG welder and Northern Tool said $200-ish for the starter tank ?!?!?! Are there any more cost effective places / ways to buy these?
I'd be open to used as well. Are there any issues with out of date threads, nozzles, limitations / unwillingness of vendors to accept older tanks as trade-ins, etc. ?
