What Gas to Weld Aluminum
What Gas to Weld Aluminumに関する深掘り解説を詳しく解説いたします。
Ah, now we’re getting fancy. For thicker aluminum—say, half an inch or more—you can mix in a little helium. Think of it as argon’s hyperactive cousin. Helium makes the arc hotter and faster. It’s brilliant for big boat hulls or truck frames.
A common blend is 75% argon / 25% helium. Some die-hards use 50/50. But here’s the catch: helium costs a small fortune. You’ll bleed cash faster than a leaky hose. Only reach for it if you really, truly need the extra heat.
Questions you’re too embarrassed to ask
“Can I use a spool gun with argon?” Yes. Argon works with MIG, TIG, spool guns, and even those little flux-core nightmares. It’s a team player.

“What about nitrogen?” Don’t. Just don’t. Nitrogen makes aluminum brittle enough to snap with a stern look. You’ll be fixing that weld with tears.
