Subject: [FlyRotary] I welded!!!

 

My first practice session was short, thankfully, because I got the nastiest "sunburn" you can imagine.  Lesson one, when they say don't have any uncovered skin in the vicinity of the TIG arc, they aren't kidding.  Despite the sunburn, I managed to stick a few pieces of steel together.

 

Cheers,

Rusty (but will it work on cast aluminum)

   

Rusty,

SPF sunblock 45 lotion will save your skin on those hot days when a long sleeved shirt is out of the question.

For aluminum, use a pure tungsten electrode (green stripe) that is sized for the increased amperage needed. Use a larger diameter ceramic cup and increase argon flow. What machine and torch are you using?

A 400 degree preheat will help on large pieces or if you're down on amperage.
