There use to be a time when the mailman would have went right by your diy mailbox. A mailbox is still supposed to be Fed approved but I don't think they really care anymore.
Turn your heat down to around 90 amps. Also turn that gas flow down. Weld S.S. as absolutely cold as you can. Only enough heat to feed the wire on an even flow.
Hi Justin, love your relaxed and informative skill sharing! Just started TIg welding because I have been soldering - electronics - all my life and doen't like to spatter around when welding something together. Still have lots of challenges to even get the arc in the middle of the two pieces (square pipes) together but this tutorial helps definately! Your cleaning tool running on air pressure is an eye opener for me, can you share what scotch type of sanding pads you use? Gonna go right to the store tomorrow to look for an air driven machine tool you are using 🙂 Keep up the good works!
Suggestion: In the air entrance you should add a small drawer in order to easily pull out the ashes. You could also add a tilting door to adjust air intake flow.
