Military use them eg, tank throws a track, broco out the problem area, then slot in a new section, and away they go. I note from the video link I added, there is an battery device with copper striking plate for arcing up, when I used them for first time, a chemical start was used to arc up, tip of rod dipped into the chemical, then ease on the oxy, slowly to light up. Before use I had to view an induction video, part of the clip showed a very large, smooth an oblong shaped granite boulder, which sat in a field, and the farmer, and previous farmers would plough this field and around the obstacle boulder. Along came the broco team, gouged out certain area to get a harness around, then truck with hi-ab appeared and removed the boulder, it was awesome viewing.
