Seriously Simo,,,its good advise your getting. The moment you stop your stainless arc welding run, you are tempted to "check it out"
Ping, ping,,ping,ping,ping as the slag self departs immediately as it starts cooling, at the speed of sound toward you, cover-up or burn up!!!
We all know we should use leather spats,,yadda yadda yadda,yeah yeah, but I dont have any.
I use simple sock guards from bunnings, nearly every day(building) they stop the welding spatter down the boots and also the sawdust from the drop saw, from filling my socks ups. Best $3.98 I ever spent!
