I had the exit bag set up and when I put it over my head I didn't pass out. I tried this a few times.
I didn't order the argon tester but unless there was something wrong with my exit bag I'm not sure why else I didn't pass out
They would know I live in a trailer park because I have a gate code and lot number.
Maybe it it was mixed with CO2 not o2. I never tested it but when I put it over my head I definitely did not pass out

Well.. I see what you're trying to say. But it's not like there aren't any welders who live in trailer parks.
It's hard to say what might have gone wrong in your case, but you're not the only one who has reported this problem of the exit bag not working as expected (without ever figuring out exactly why.) Apparently it sounds much easier on paper than in it is in actual practice to get one of these damn bags working properly.
One potential issue could be that argon is heavier than air (whereas nitrogen is lighter). Thus nitrogen will rise in a closed space, while argon will sink; this may lead an issue where you are still breathing air and CO2 because the bag isn't being sufficiently flushed. One possible way to address would be increasing the flow rate on the regulator; some have suggested
25lpm for argon, compared to 15lpm for nitrogen. Consequently this means using up the gas almost 2x as quickly, so a larger tank would be ideal.
I'm much less concerned about the possibility that welding companies would deliberately sell defective argon... this has only ever been reported with helium for balloons (which the added air doesn't affect). So my intuition is that your attempt failed not due to the argon, but to some other factor. If you can check your receipt or packing slip for the cylinder it should state clearly if the contents is 100%argon or if it is a 75%argon/25%CO2 mixture.
