The YouTuber "Cutting Edge Engineering" uses it to remove really large quantities of steel, cheaply. E.g., https://youtu.be/5nfxXcAC_Eg?t=197
Yes, it's good for stuff like shown in the video. Gouging out a cracked weld for repair etc. Actually what that guy did in the vid was a neat clean job. I tried it once about thirty years ago with a carbon rod and never tried it since.

Joelee. Back in the 80s. I was working at a place building heater treaters for the oil fields. Its has a tank about 10 ft long and 4 ft. in diameter. I came in one night to find a tank on my rolls that had been stringered with stick and capped with wire. NoNo! Cap was full of pinholes and besides there is no code for it so the cap had to come off. The forman wanted me to grind it off. There was a gouger laying in the break room. I got it and started ripping it out and when I raised my helment there was about 12 guys watching behind me. I couldnt believe that that many welders were inexperienced on one of them.
