I can't tell if you are using Stainless Steel Flux Core (Only available in .035") but if not... while welding with S/S Wire and a Gas Mix...it is possible to weld INTO Mild and Carbon Steels... but the REVERSE approach of using Carbon Steel Flux Core Wire will WEAKEN the S/S substrate and invite fractures. THIS Flux Wire is specifically made for Welding Stainless Steel
GAS FREE and will produce astonishing results as long as you don't try doing lengthy, continuous welds or attempt to use it on Thin 16 Gauge S/S ...as the 'Burn-Thrus' on your work pieces will frustrate the Hell out of you.

A One Pound Roll of this Stuff from
Blue Demon goes for around $33.00 on Amazon. Pay Very Close Attention to the issues of Changing Polarity, The Toxic Fumes Indoors, The "Bacon Spatter, BBs & Buckshot" Mess that will be left behind if you don't use some "Spatter Spray" ahead of mock-up time. The Wire Gauge OD Limitations and the other problem of having Pre-Sets on Low Buck Machines with limited Wire Feed-Speed and Voltage settings come right along with using 120 VAC Machines in 15 Amp Circuits and Limited Duty Cycles:
THIS
Stainless Steel Flux-Core Wire is great when used with a lot of practice to find the right combinations of Wire Feed, the Correct Torch Angle
(5-10 degrees when pulling the Wire) and your Drag Speed and Heat Settings. If you can get the right 120 VAC machine that can handle around 140 Amps, Welding Stainless Steel on anything between 1/8" to 1/4" in thickness can be made to work ...and maybe even made to LOOK pretty good, too...
Watch what this Expert manages to do with it on a 240 VAC Machine... WITH NO GAS:
To Whom It May Concern:
I CANNOT STRESS THIS ENOUGH... INHALING HALIDES OR HALOGENS LIKE
HEXAVALENT CHROMIUM VAPORS WHEN WELDING
STAINLESS STEEL WITH ANY TYPE OF WELDER AND RODS OR ELECTRODES
IS EXTREMELY DANGEROUS.
DO NOT FLUX-WELD INDOORS WITHOUT A CONSTANTLY WORKING EVACUATION HOOD OR WITHOUT USING A STRONG FAN OUT OF DOORS IN ORDER TO BLOW THESE FUMES AWAY FROM YOUR FACE AND CLEAR OF YOUR BREATHING SPACE.
THE INCREASED RISK OF A FIRE HAZARD IS ALSO MOST IMMEDIATE AND UNAVOIDABLE IF YOU ARE ATTEMPTING TO FLUX-WELD INDOORS:
An Anecdotal Reference that cover these points in scant detail:
Can you find stainless steel welding wire that is flux core? And if you do can you use stainless steel welding wire flux core when you have a home MIG welder?
