this stickout is huge, that cup is amazing

[@Smffab]

Furick cup for the win

[@MIEDEPAIN20011]

It's pretty impressive how your tungsten sticks out from the cup 😮

[@Smffab]

Yeah that seems normal to me but for some people it’s not. I must admit it is stuck out more than I normally would have it but with the large cups it’s ok.

Gratuitous tungsten exposure, oooh I bet it's thoriated too.

[@Smffab]

Quite normal stick out for the cup size. The tungsten is 2% Lanthanated.

[@Smffab]

Yes I use the pink cups for aluminium welding and like you say when you need to get into a tight space, they are quite handy still.

[@Smith944]

nice weld.

[@Smffab]

Thanks 👍

like to know if there is need to purge, or just tape up the ends (exhaust flow)? thanks

[@Smffab]

I always purge when welding stainless steel. Use tin foil, silicone purge plugs or tape and then fill it up with argon making sure there can be some flow out through a small hole. I suppose with something like this you wouldn’t have to purge it if you controlled the heat input by pulse welding. Thanks for your comment.

[@kathysarmcandy1992]

Excellent Sir. Other than your stick out may be a few 10/1000 too far. Carry on.

[@Smffab]

Thanks

[@purezeppelinrock8613]

It's a fupa cup, that's the point lol

[@Smffab]

Haha yea exactly

What gas flow you have at this stick out?

[@Smffab]

About an inch and 30 cfh

[@atomicgarage5606]

Just use a step bit

[@Smffab]

Thanks for your recommendation. I find the hole saw works great. Cutting fluid is preferred which I didn’t have at the time.

[@Jessie-fz2bl]

Get a 02 sensor saddle it’s much easier quicker

[@Smffab]

Easier to weld but I prefer the look of the standard o2 sensor bung.

[@k6ul]

How come i see black spots now?

[@Smffab]

Haha sorry about that

[@TheLairyLemur]

"Eyes!"

[@Smffab]

Sorry for the bright lights, I will have to fix that next time.

[@dnbstreamer]

Haha you said bung
