I'm learning so much.

Sweet vid , been a subscriber after watching you tig that flagpole.

[@DarlingtonFarm]

Oh cool, that was a fun one for a buddy of mine

I’m new to TIG welding, and I am interested in sanitary welding. What size of tungesten and what type of tungsten do you use for sanitary?

[@DarlingtonFarm]

I use 3/32 for pretty much everything and the cheap grey stuff off amazon.

[@gunnarl5087]

@@DarlingtonFarm thanks! I have tried 1/8 and can’t keep an arc going. Granted, I’m Tig rigging off of a Miller Thunderbolt. But I do have a Ranger that I have had better success with tigging off of with 1/16 tungsten

[@rowlandcrew]

what did you do to passivate? And, when do you use the cougartron?

[@DarlingtonFarm]

I usually use it for hard to reach spots or stuff that was in contact with carbon steel, it will get an acetic acid bath

What polishing wheel do you use on your die grinder?

[@DarlingtonFarm]

Grey scotch bright, they are awesome for polishing stainless

[@marcusandrew1047]

So you don’t have to scratch start?

[@CrossCutTabb]

So why no filler rod?

[@DarlingtonFarm]

Try to reduce the chance of introducing any kind of porosity where bacteria can grow. And it's not really needed, the wall on the tubing is only .065" so you can melt through in one go no problem
