Who's ever welded (stick or wire) with fabric tennis shoes on? How many have done the dance when the little dingelberry bounced off the floor, onto the top of your shoe, then promptly melted thru the shoe and sock, (and part of your skin) coming to rest between your toes? I've got both hands up because I didn't learn my lesson the first time. (and I ran out of hands because I didn't learn even after doing it twice........)
I have my share of welding scars and permanent problems. Also been zapped more than once in damp locations. I always feel better after AC current runs through me. DC, not a big event.
I really dislike them getting into your ears. When one hits just right, you can hear the sizzle and burn really well.
