Mig Flux core wire problem
I was using that ten gauge rubbish as well. Just converted to c02 yesterday. You used to be able to get out of date fire extinguisher bottles converted to run c02, but they (Asko) are no longer putting names on the list for these (in Chch). Brand new bottle was $350, full incl and $18.50 to refill. I already had the reg, but they are around the $100 mark from memory.
Ugly is a state of mind..... and the state of my truck!
