Sorry if I’m not posting this right. Newby here. I would like to take welding classes so I can use the welding equipment. I am particularly interested in using the TIG machine. I would like to make a small repair using 312 filler in a weld on a tool of unknown steel alloy. (a socket welded to a steel metal strap torque-wrench adapter) I have more than 60 years welding experience so I probably need to get rid of some bad habits before I fire up any of the equipment. I would appreciate any help anyone can offer. Thank you.

I went ahead and moved it into the “metal shop” category where the folks who can assist are more likely to see. FYI the chair of the metal shop committee is not a talk user and the best way i know to meet with him is to hang out there. I’ll tag the co-chairs who occasionally pop in on here. @texastboneking

Last I knew the TIG was not ready for prime time but I’m weeks behind on info. …
Hey meant to post this earlier. I will be posting some classes to the calendar this weekend. A safety class and a stick welding class for the month of October. As far as TIG goes I can talk to Lee and ask him about it, but if you’re interested in the two I just mentioned keep an eye on the calendar. Thanks for your interest.
I may be interested in the TIG as well. I have a generic TIG setup at home. I do need to get my Argon bottle refilled & re-stamped/certified. My setup is just the torch on my AC/DC arc welding machine. No foot pedal. I do have experience with arc, mig, brazing/silver solder with Oxy Acetylene.
Thursday night when giving tours one gentleman on my tour was interested in welding and apparently has some experience in it. In the lobby Stan Simmons, Russell Ward (Gimli) and I spoke with him about it some more - along with current issues regarding plasma cutters etc. The upshot is he seemed very inclined to join and teach multiple classes on beginning welding, TiG, etc. By interested, he we went out to the shop and he reviewed the equipment more closely, how many helmets, etc. to see what class sizes would be like. We all strongly encouraged him become a member … even told him how the Honorariums would pay for his membership! Hopefully he will do so and welding and the Metal Shop will undergo a minor renaissance and become very active.
The three of us all agreed there is pent up demand. I know it is frequently asked about when giving tours on Thursday night.
Of personal interest, does anyone know what toxic gases the portable fume extractor is good for? Specifically, Stainless Steel, have some tack-type welding to do - prefer that to silver solder. Thanks

Welding is one of those skills I have always wanted to learn. Since I know very little, a nice start would be some links to some sites that tell about the types and uses of various types.
It’s designed to be a fume extractor. It’s not a small one at that. My engineer buddy of mine suggested we use that instead of spending a lot of money on a fume hood.
Here is the spec sheet on it. It’s the mobiflex 200m. http://www.lincolnelectric.com/assets/global/Products/K1653-2/e1321.pdf

Could they be spot welded? Much less fume production. @afloyd might be interested in using his some more. …
I probably should have expanded on why I’m referring to it as “tack-type” welding. It would be welding where two 1/8" SS rods come together rather than running a bead. A spot welder would not be able to get into position due to tight angles, confined areas, etc. Looking to fabricate a rolling ball sculpture.
The filter we have is capable of using an activated charcoal filter but I can’t find anywhere that says it will filter out hex-chrome if this filter is used in addition to the other particulate filters. However, I did see some weld fume extractors that were HEPA filter based that were capable of doing so due to allow for welding stainless. Hex chrome fumes and dusts are highly toxic, carcinogenic and can cause a host of respiratory tract issues. Choosing the appropriate filter media will allow welders to avoid inhaling this dangerous smoke. For stainless steel and galvanized steel welding applications, a HEPA filter will provide the needed high efficiency filter media to capture submicron particles and exhaust clean air.
