PREPARING YOUR WORK AREA
1. You must have a sturdy work table that is open below the area you are cutting.
Molten slag will be blown through the work metal, and must be able to fall away
freely
2. Your work table must allow the work metal to be rmly clamped to prevent it
accidentally falling or moving.
3. The oor and surrounding area of your work site must not be ammable. A clean
cement oor is recommended. The cutting process will eject molten metal slag
onto the oor, and it will scatter for 8-10 feet or more in any direction. Have an
adequate re extinguisher available if needed.
