Had to cut a piece of 3/8" steel today while scavenging. Here's a shot of one of the cuts. This is probably the first it's been used on heavily galvanized steel. It acted like it was broken. Wouldn't cut worth a hoot and tip got all clogged with boogers. After grinding the galvanizing off it worked like a champ.
The steel is from part of a pipe support intended to live outside for years and the finish resembled the appearance of pole line hardware. Grinding the galvanizing off took quite a lot of effort. I could feel and see when the steel came through. Of course when it began throwing sparks it was a sign. It was all done outdoors with a breeze going, but there was still an odor like a mixture of onions and armpits.
