how mu cfh are u guys running? i was running around 20 w/ the 10 and large lense, now i recieved my 12 and have to bump it around 35 and my arc is still jumping like it has no gas! maybe have a leak somewhere? or is this normal?

[t_cel_t]

max you should ever be running is about 15, 10 or so with a lense.
only thing i know that makes your arc jump around is magnets and dipping your tungsten in the pool. if there was no gas it just fucking sparks and smokes and everything goes black and sooty.

Way too much gas. You're blowing the arc around. I rarely run over 15, and I weld thick stainless at work.

i run around 15-18 depending on how nice i need the weld to look, or if i'm doing al i will turn it down lower

17 with my #12.

17 with my #12.

anyone have the part # for a #12 gas lens cup? i talked to the local weld supply and they said for my miller the biggest they stock is #8... or are these for the medium size lens?

[Corey]

no the largest they make for that is #8. the gas lense for a #12 is huge.

isnt a #12 what you guys use for stainless? i have a #8 and it works pretty good with cfh at 15, amps around 60 when adding filler. whats the #12 for?

[1fasthf]

more gas coverage for stainless.

i mean what torch, i found out my 250syncrowave has a 200 amp torch, and was told i should go bigger. it overheats a little, esspecialy doing aluminum cly head work. im also switching to argon 75%/helium 25% mix for heavyer aluminum work... i need the bigger torch to run the #12 gas cup right

If you do a lot of aluminum a water cooled torach is a must. For the #12 cup/gaslense you just need to buy a large gas lense and then the #12 cup. You will need to find the correct adaptors (little white rings) that makes up the room to the torch head.

It's not to hard if you have a decently stocked welding supply store to look through. I have a large gas lense but haven't got around to using it.

[90turboteg]

ya i have a watercooled torch but the guy said its only a 200amp one? but ya i ordered just reg size gas cups and lense, i remeber i acsidently ordered a #12 for a large gas lense and it was over and inch round. i was like i dont thing thats right. ill have to order a medium lense setup then also...

[Corey]

yes the gas lense for a #12 cup is huge, but they make the large lenses for  size 17 and 26 torches if you want to use one. it would work well for a part that doesnt have tight spots to be welded.

I had planned on using mine on dp's and tubing in general. I can't get my SS tubing welds to look all pretty there dull pink in color.

[1fasthf]

i have the 12 on my wp-17 torch and it has helped tremendously!

[90turboteg]

ya i figured my #8 is why i just get light red color only, welds look good but seems like theres not enough gas coverage. not as nice as when i used a air cooled 200sx with a #12, man the welds were beautiful...

[1fasthf]

yea i had the same problem w/ my 8 if i wantd the goldish color that u want then i could only weld 1/2"

now w/ the 12 i can go alot farther

u really want ur welds to be a pinkish/gold color

[t_cel_t]

just to confirm, the number on the cup is just the diameter of the cup in 16ths of an inch?
#12=12/16=3/4 inch?
