Re: Hood shade for pulse Tig

Thanks guys and yeah I tend to go as low as I feel is safe, but it’s always a big compromise in puddle visibility. I have a 3350ADV, but the auto mode only covers a small range. So far the projects I have done were at higher frequency pulse settings but want to gain skill with the low frequency lay ...

Hood shade for pulse Tig

What do you guys find best when doing low frequency pulse on stainless? Particularly if your bkg is quite low so a large arc differential. Lean toward the low or high shade side ? Thanks.

Re: Tungsten cleaning

Concerns noted, but confident no chance of any acid residue left. There is probably a higher risk while working with a cast repair that had unknown exposure, and that's something that would be seen fairly often in a welding shop I would imagine.

Re: Tungsten cleaning

I have 2 thoughts: first is, why immerse the tungsten in acid? A quick regrind and twist with a ScotchBrite pad turns tungstens back to a bright shiny level. Heck, I don’t even polish mine up 99% of the time. Second, I can’t imagine that introducing acid into a plasma arc has benefit, in fact, it m...

Re: Tungsten cleaning

Thanks for the replays. From a chemistry perspective, it seems fine as aluminum is highly reactive to HCL and tungsten non-reactive. Whether the doping (2% lanth) is affected is unknown (will look into that) but the surface finish of the clean area of the tungsten does not change. Also, at least at ...

Tungsten cleaning

Hello, first post here. Learned a lot from Jody’s content. I’ve been learning Tig for six months now. Have a fair amount of stick experience in the past building 4x4 truck stuff and a trailer. So far built a custom stainless roof rack for my wife’s car using Tig. Also some aluminum repairs on dirt b...
