What is the maximum cutting reach below the base plate, I need to cut a slot into a 200 Lb c-channel that want fit on the cutting stand. A quick response would be helpful I’m going to find out in about a hour. ---

Depends on how your Z axis base plate is mounted and your torch and its mounting position. Z has about 2” of travel. Whether you can successfully probe the work surface at the extreme is another question. Not much push from the spring at that point. ---

Why aren’t you cutting from the flat side instead of from inside the channel? ---
