Therefore, the recommended shielding gas to use for short circuit stainless steel MIG welding is a tri-mix shielding gas, such as 90%He/7.5%Ar/2.5%CO2. The high thermal conductivity of helium helps provide a flatter weld bead and good fusion into the base plate.herefore, you do not want to use a completely inert shielding gas, such as 100% helium or 100% argon for stainless steel MIG welding. The arc characterisitcs would be poor.
These days, we use car horns to:    Alert other cars when you're coming around a blind corner  Alert pedestrians who are not concentrating on where they're  walking  Alert other drivers when they are about to make a driving fault  so they can avoid hitting you     And that's about it.
