Welding Co2 Gas. These fluxes will act as a shielding environment against oxygen during welding but in co2 welding co2 gas are used as a shielding environment. Co2 welding is the welding technique also used in most of fabrication industry.
It is used in MIG welding when speed is more critical than weld appearance. 390g pressurised mild steel bottles Designed for optimum performance. Again many welding supply stores carry their own mixture that can improve the weld quality and ease of welding on stainless steel.
80 Argon 20 CO2 is a common mixture for MIG welding No more leasing fee you can now refill the bottle or swap it for a new one at the pick up location below.
If you plan on MIG welding stainless the best gas mix is 90 helium75 argon25 CO2. This characteristic results in both benefits and negatives. If either the melted filler material or the metal being welded is allowed to oxidize the weld will fail. Some MIG applications even use pure CO2 as a shielding gas.
