I went an got myself a new to me mig welder.
Now, in an effort to keep my wallet moth free itís time to buy a bottle and get some shielding gas. Thatís about the extent of my knowledge. From minimal research Iíve done online a general list of weld quality is below starting at worst getting to best.
Self shielding flux core
Tank prices Iíve looked at are $150-200 for either a 80cf gas bottle, or 20lb CO2 bottle.
Without verifying Iíve seen that price goes up along with general quality following the same list above.
Pure CO2, is cheapest and lasts much longer then the others.
Iím leaning towards pure CO2, as Iím a hobbiest only. Is that a reasonable choice or would I be just as well off with self shielding flux core? If thatís the case Iíd probably rather go Ar.
How long will 80cf last? Some estimates were only 4-5 hours. Iíd probably end up with 2 tanks if thatís the case as I hate pausing a project because I ran out of supplies, and the shop is closed for the weekend.
