I'm wanting to switch from co2/argon mix to straight co2. Have a few questions that I need help with:
1) Supplier suggested 20 lb co2 bottle. Said it would last 3 times as long as my 125 cu ft co2/argon mix. Cost about $20 to fill the the co2 bottle........about $40 to fill the co2/argon mix. Is he correct about how long it would last?
2) Thinking of getting (from Craigs List) a large o2 bottle and swapping it for a large co2 bottle. How long could I expect this bottle to last compared to the 125 cu ft co2/argon bottle? Cost to refill is about $32.
My welder is a Miller 130 and portability is not a problem. Have a stick welder for the heavier stuff. I have been told about additional weld spatter resulting from using co2.
Comments and suggestions would be appreciated.
