type of gas and pressure setting for mig
Now I'm really confused. I bought a cheap mig, sold as "Combo Mig-with gas or without" . Wasn't surprized to find it didn't come with a gas bottle but it does have a place for one and a hose. It actually works well with flux core wire (included) so I thought if I bought a bottle It might work as well with gas. Welding supply store sold me a small bottle filled with argon and said thats what I needed.Also bought a spool of wire for stainless and one for aluminum. The manual shows diagram to reverse cable connections to change to non-flux core wire but no specs for connections or guages/pressure etc. Had an extra set of guages and fittings and guessed around 12 lbs for pressure. Gas comes on and off with trigger and sounds about the same as I remembered but it's been 10 years at least since I used a mig. Tried to weld thin stainless but with all the wire speed, heat, and pressure combinations I tried, couldn't make a weld I would trust (or want anyone to see) A friend told me he didn't think you used argon but a mix of CO2 and something. Anyone out there have this info ? -- monkeydave |
