Abstract
A fluid jet cutter using an articulated boom support system is disclosed. The cutter utilizes a support system which allows rotational translation in all three axes. The boom system allows displacement of the cutter over a broad area. A jet catcher is attached to the cutter head to catch the cutting jet. A deadman switch arrangement prevents the operator from contacting the cutting jet. A vacuum system is linked to the catcher and a column that supports the boom to remove cutting debris and waste fluid.
