Old timer at the union hall changed my mind about purge welding

I always thought purge welding was overkill for stainless pipe but this guy who's been doing it since the 70s showed me his photos of wormtrack contamination on a job from back in the day. He said 'kid that job cost the company 15 grand in rework' and that hit me hard. So I tried his trick of using a simple cardboard dam with argon trailing on a 6 inch schedule 40 job last week. No sugaring at all on the root pass and I'm never skipping it again. Any of you guys got a go-to purge setup for tight spaces?

Yeah, tin foil and a split hose clamp works great for tight spots.
