tungsten

[pothole]

Hi all, I have recently purchased a syncrwave 200 and was wondering which tungsten (color) would best suit this machine for welding aluminum?

[shovelon]

Easiest to find is orange(ceriated).

Pure

[bababouy]

I use 2% red for everything. I have some pure green stripe that I use for small guage aluminum, but if I'm welding over 120 amps, I use the red. I have a sync 200 also and I mostly weld heavy stainless with the machine at 160-200 amps

Red, green and orange all have there place for that machine as far as bead profile is concerned. Balling effects etc. with amperage and material thickness, esp with aluminum.

Pure (green) tungsten is not recommended with a square wave machine on AC. use ceriated (orange)

[Helios]

2% lanthanated for everything

Try ebay for good prices

Try the purple tungsten for that machine they hold there tip amazingly well the same if not better than 2% LAN.

Why is that? And where did you get this from? I have used and still do use pure with my lincoln square wave and it works great... i use ceriated on thin alu. Under 3/16. Anything over i use pure

like weldon said....

I use pure on a synchrowave 180, and have used it with the 250, 350 and a portable hf-251d set up with no problems. I think there is some confusion in the posts here, Miller doesn't recommend using pure tungsten with any of the inverter machines. I think this point may have gotten lost in translation. As for the Ceriated tungstens, I think they are ok , but i personally prefer the 1.5 or 2% lanthanated. They seem to give the sweetest characteristics with all the gear i use. I see they are bringing the E3 tungsten out in a big way as the latest greatest thing for all things Tig welding. I have researched this and it seems to have very similiar composition to the 2% lanthanated. I understand it has lanthanated as well as rare earth components?

E3 is 1.5% lanthanum with trace amounts of yttrium and zirconium.

Pure "is" commonly used with sinewave tigs. Lots of people still use it.

Tried E3 on alum. Have to say it is not half bad.

tungsten

Bought the last 3-pure our LWS had in stock. He said can't reorder? Going to E3 in future.
Tried the E3 today with dynasty on small Alm job
Same opinion as shovelon not to bad.
