Duty Cycle

Duty Cycle is the equipment specifications which defines the number of minutes
within a 10 minute period that a piece of equipment can safely operate.

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 firmly clamped to prevent it
accidentally falling or moving.
3. The floor and surrounding area of your work site must not be flammable. A clean
cement floor is recommended. The cutting process will eject molten metal slag
onto the floor, and it will scatter for 8-10 feet or more in any direction. Have an
adequate fire extinguisher available if needed.
