I’m in Australia and just getting into tig. I’ve been watching your stick / mig
vids for years – a great source info – thanks so much. I’m keen to get a tig finger or two and some torch accessories and I’d like to support WTT in doing so. So I could either buy direct from the Weldmonger store and have it shipped or perhaps you have retailers in Aust that buy from you and resell ?
The “sugaring” referred to in this video prompted a question for you Jody. It’s ‘sugaring off’ time up here in Quebec and I often help a friend gather maple sap from his sugarbush. He uses the old-fashioned method where we empty the sap from a pail (or pails) on each of the trees into a large bucket which we then hump out to his waiting tractor on an access road. It’s then dumped into one of two large stainless steel tanks – one on the front & one on the back of the tractor. These tanks have an annoying tendency to leak from the seams & my friend has routinely asked if I could TIG weld the cracked portions. So far I’ve been telling him that between my lack of experience welding this material and the issue of getting the interior of the tank clean enough to weld, I’m more apt to just make the seams (and the leaks) worse. The issue you raise, i.e. argon backing to prevent weld contamination, just makes my chances of success all the more unlikely. Because of their size the tanks would require a fair amount of argon to back-purge. Any experience with something similar or ideas on how to make a reliable repair?
Can you use Mig Argon mix for the backing gas or is it essential to use pure argon? Main reason most TIG welders will have access to a Mig set with its gas cylinder that could be used for stainless backing gas only. And argon mix is generally cheaper than pure.
