I have been using Nickelbacks for a couple of years and they work great for me. Easy to get on and off, and no problem with sweating. I usually get multiple uses out of them instead of throwing them away after each use due to tearing and sweat...

What grade of stainless steel is the exhaust pipe? A lot of OEM stainless exhaust is type 409, which is a ferritic grade. A few carbon steel tacks on 409 is not a big concern, especially if whoever TIG welds it grinds out the tacks and welds over that area with ER309 wire. Or you could use ER409...

What alloy was used? If the frame was manufactured from a heat treated aluminum (such as a T6 grade), then welded in the assembly with no heat treatment after final welding, then repair welding the gouge is no issue. If the entire frame was heat treated after welding, then the entire frame would...

Same here. Uniform of the day for yard work is straw hat, long sleeve UV shirt, shaded safety glasses, jeans and lots of sunscreen.

It's not for the faint of heart... But you eventually either get acclimated to it or become addicted to air conditioning.

Similar to the Navy method to unclog a toilet using the firehose. It did tend to leave brown stains on the ceiling though...

I thought you were supposed to put it in a paper bag, light it on fire on their front porch and ring the doorbell.

Yeah, mixed gas (other than Argon/Helium) would not work on aluminum. Does the cylinder have a label on it?

Just went through this with my son's AC. Bad high pressure switch, then the capacitor went out and the fan motor died. $200 service call for the pressure switch. Fan motor was already squeaking when the pressure switch was replaced, then it just quit. I put in a new cap and it ran for one day...

But, is AI correct when it says AI is not always correct...

I'll just leave this here:

Very low chance of contamination, standard practice is to pull a vacuum on the cylinders before filling. Are you sure it is labeled as welding grade argon?

Can't you pull the front cover off the panel and see what size conduit connector is used on the main supply?

For welding mild steel to an unknown hardenable steel, I would use E309 or E312 stainless stick electrodes with a 400 F preheat of the hardened steel. The stainless electrodes have much more ductility than carbon steel electrodes and the austenitic welds will not be susceptible to hardening by...
