Can I use some of the soft stainless tie wire I have a lot of, as filler rod with my Miller Diversion TIG??

What he said. Proper filler wire is cheap...get some.

Re: TIG question
Will be non-critical welding of Stainless thin angle, for a frame for the edge of a marble top table(OT, sorry) No bolt handle welding here.

Re: TIG question
Still...filler wire is dirt cheap. You already have a $1k plus tig welder...just buy the filler and do it right.

Re: TIG question
My welding teacher taught us that you could shear off a 1/16" wide piece of the sheetmetal that you are welding and use it as filler metal in a pinch.
He actually had us try it and it indeed worked...

Re: TIG question
2156, that is true for welding of stainless in most cases...if you don't have engineering requirements which specify the required filler to be used. When gas welding, that's not so true as the base metal will not include the oxidization reducers that the appropriate filler has. There is also a similar issue when TIG welding non-stainless steel as the filler includes oxidization modifiers to ensure the integrity of the weld itself.
With stainless, using the base metal as a filler is one thing, using a random bit of wire with unknown metallurgical properties is another thing entirely. More importantly though, why would one use something other than the appropriate filler wire unless you were doing a repair on a restricted timeframe (usually a field repair) and didn't have the appropriate filler available nor time to go get it.
Filler wire for TIG is inexpensive in most cases (until you get into things like welding beryllium copper, copper aluminum alloys, etc... where the filler wire is very expensive).

Try welding 6061 Aluminum with a little strip of 6061 sheet. It welds, but promptly cracks. You must have non magnesium-bearing alloy (4043) to have success...except when post-weld heat treating, where 4643 must be used.
I've ever welded using a piece of coat hanger - but it was ALL I had, and I needed it to be welded two hours ago.
I'd recommend you get some 309L rod for your prohect, as it's a good do-all rod for most projects with stainless, and doesn't mind flowing/alloying with stainless or plain steel.
Good luck!

Re: TIG question
On a side note not asked in your post, but of importance is the use of "back" gas when tig welding stainless.
If you do not use argon on the back side it will look like something out of one of our caves here in Missouri, but if it is non critical, non structual go for it and don't look back.
If you need pictures of a back gas diffuser send me a PM with your email address and I will send you a picture of the one I use 99% of the time welding SS.

I was taught the same method works great.

Good point...forgot to bring that up myself.
If it's not food grade or held to similar standards, you could also use solar flux, or a ceramic backing strip which is removed after the weld is completed.

Re: TIG question
You can use a copper backing strip also - works well, and can be fitted to the particular application at hand. Like this:
