;) Hi is anyone familiar with duramold 5 aliminum. Looking for any helpful info. The specs say zirconiated tungsten. Ok I get that. But 100% helium shielding gas for AC current seems a little extreme. They also recommend 5356 filler rod heated to 100 degrees for 24 hours. Is this bullshit or is it business as usual. I'm thinking keep it clean, slight preheat to the part and maybe 50/50 argon/ helium mix should do it. Any info would be a help. Thanks.
