Recommended gas pressure - Miller Welding Discussion Forums
2011年4月7日 · For flow, it depends on your welding habits, size weld, position, and the diameter of the cup. For reference, I start at 20cfh for a 5/8" ID nozzle, 30 cfh for a 1" nozzle, and adjust from there. Nothing welded, Nothing gained
CO2 vs Argon/CO2 mix?? - Miller Welding Discussion Forums
Straight CO2 is cheeper then steel mix but steel mix will produce a cleaner weld when running solid wire. 100% CO2 will get a little more heat in the weld so thicker sections can be welded but again it won't be as clean as a steel mix gas. 100% CO2 …
Argon CO2 mix OR Co2 for Mig welding
2009年2月12日 · Once you use it for a while rent a co2 bottle and weld the same material with 100% co2. Then if you like using the co2 only on particular wires or material thicknesses buy a bottle of co2. The 75/25 would be a good general gas for a first bottle, and there are several good solid and flux cored wires that work for it, but there are some that ...
laying bottle on its side - Miller Welding Discussion Forums
yep, like mac said, its all fine with C25 just strait Co2 and acetilean, need to be upright. the Co2 can be caried sideways then stood up and used almost right away, the acet. is the one with the fiber fill and needs to be alowed to set upright for atleast 3 Hrs befor use. the stand and settle time is a lil hazzy as the the exact time some say longer some say less depending on its sideways ...
Welding Gas Differences - Miller Welding Discussion Forums
2010年5月4日 · With this type of process, there needs to be a certain level of CO2 (minimum 25%) to support the arc. C-25 (75% Argon/25% CO2) or 100% CO2 are the recommended shielding gases for "short-arc" transfer. A globule of molten metal forms on the end of the wire. When it's fed and makes contact with the work piece, it forms a "short circuit."
mig welding with CO2? - Miller Welding Discussion Forums
2012年2月28日 · 20# CO2 tank equates to about 174CF of Gas/ by yer flow rate and that is how long it lasts. CO2 is usually cheaper and a 20# tank is a blt easier to transport BUT some people don't like the way it welds- produces more spatter.
Soda co2 tanks for welding? for MM35 - Miller Welding Discussion …
2011年9月1日 · Industrial CO2 is fairly pure since there is a good difference between boiling points of Ar and CO2. Soft drink CO2 is a byproduct of the oxygen production (like liquid nitrogen). While there are CO2 pipelines pushing product from natural gas refining for use in tertiary petroleum extraction (Permian Basin, Kinder Morgan Pipeline), this isn't ...
MM211 welding steel with 100% CO2
For GMAW mild steel how much worst is the splatter with only CO2? I'm a rookie at this, only having laid crappy beads using a HF Mig 151 clone. I'm thinking of getting a 211 to improve the machine part. Would welding with only C02 be much harder to do with the skills not transferable to Ar/CO2 welding?
Need wire that is compariable to 7018 stick rod and which gas to …
2013年1月21日 · The best and fastest process is probably dual-shielded flux cored welding. This wire has flux built in like 7018 and uses a gaseous shield, usually by C02 or a argon co2mix. There are numerous options of what brand size and type of gas to use.
Co2 VS C-25 for mig - Miller Welding Discussion Forums
2006年5月7日 · yes you will hate it after using c-25 straight CO2 is great for penetration but **** for looks, it welds uneven, spatters like crazy. at first you will think you don't have the gas on it spatters and bubbles so bad! i personally hate welding with straight CO2 but at half the cost alot of people still use it. if you are just welding stuff together it holds great but if you are trying to …
