you might want to try esab dual shield cored wire. ive used it on air tight/water tight projects with a lot better success than bare wire. you still need a shielding gas such as stargon or 75/25. i have always had porosity at the start and stop areas with solid wire , but not with the dual shield.Garnification said:I used 035 solid wire e70s-6 I think is the #. I have been using trimix. 90% argon 7.5 c and 2.5 o2. Seems to make nice welds. In the past I just used 75/25. And don't be afraid to turn up the gas regulator. Helps to keep the porosity out better.
RSI is the company that I dealt with.
