I had positioned the RE on my car, and tacked the brackets in place. Made a quick jig to hold the RE about waist high so I could weld in a comfortable position. Up to this point all is well. Decided that it would be real nice to sit and weld the brackets, pulled up my favorite plastic porch chair, the kind with a solid bottom, all is still going fine. Didn't take into consideration that mig welding produces "HOT" slag balls, which then will fall into a solid bottom chair, run into the crotch area and give a person really "HOT" balls. Glad no one was around when I jerked my pants off at the sink.
