How strong is the machine?
The PlasmaCAM machine is more than strong enough to handle steel plate up to 1 inch thick. (A 4-foot by 4-foot piece of 1 inch thick plate weights about 660 pounds.) We did a stress test on a machine, hoping to determine how much weight it could hold. As shown in the photo, several pallets of heavy steel parts were weighed and stacked on top of the machine.
Even with over 10,000 pounds of weight on it, the frame did not collapse. This means that the PlasmaCAM machine is more than ten times as strong as it needs to be.
