I just bought a Miller dynasty 200. I have a couple of questions

1) Can some one please tell me what type of tungstens and filler metal u use for the manifold sch bends?

2) to weld 16 guage aluminized steel, stainless and aluminum pipe what tungsten and filler do u use?

i was messing around with 2x2 angle iron i got alright looking beads but they look thing I am just using the tungsten that came with it but im just trying to get and idea what u guys are using.

and what cfh or lph do u guys use while welding im using about 20 cfh

I tried to weld Aluminum angle with a thoriated tungsten(i know thats the wrong one)
im supposed to use ceriated correct? i dint have any i just wanted to see what would happen I tried welding and the whole metal got wet even after i lowered the amperage the filler dint even come out in beeds a pool dint form it all just melted i guess thats why they say to use ceriated?

I want to order tungsten right now im thinking 1/16 and 3/32 on the miller site it say 3/32 is upto 250 amp range i max out at 200 so i should not need more right?

My goal is to weld ss/ mild steel exhaust pipe intercooler pipes and hopefully eventually try to weld a manifold together.

I see some insane welding pics on here im trying to practice but i am not sure if im using the right tungsten filler sizes and I dont want to try every combination possible hopefully u guys can guide me with ur knowledge.


thanks

 

There are lots of resources out there when you are new to tig welding.
Millers site is the perfect place to start, they have lots of literature on the basics, how stuff works, tungsten selection/shaping, what fillers to use etc.

Take a look there, it will answer most of your questions.

And in regards to welding the aluminum with the thoriated tungsten, you should have no problem using thoriated with a inverter machine, it works perfectly fine along with the other rare earth tungstens. You'll probably need to do some reading and play with all the fancy settings on that nice machine before you'll be able to jump into welding aluminum, but you definately should be able to with what you currently are using.

 

X2 on MIller's website. Fantastic resource for sure!
