I found a few pieces of laser cut 1/4" thick 304L stainless in one of my scrap buckets so I am using it for a lap joint video. Stainless steel requires less amperage than carbon steels so even for 1/4" thickness, I only used 95-105 amps. In fact, I was plugged in to a 115volt circuit for this video.
