Hypertherm’s MAX100D is a dual-gas system designed for cutting most metals from gauge to 32 mm thick. In addition to hand cutting, it can be used with a machine torch and a THC-2 Torch Height Control system for highspeed mechanized cutting.

The MAX100D provides continuously variable current output from 30 to 100 Amps for optimum performance on all thicknesses of metal up to 32 mm thick. This allows the operator wide variations in cutting speeds on the same thickness of metal. Two nozzle sizes (60-Amp and 100-Amp) provide high-quality cuts throughout its range of cut thicknesses.

The system can also provide a continuous pilot arc which allows high-quality cutting of perforated or expanded metal without any appreciable deterioration in parts life. This feature is only available for use with the 60-Amp nozzle.

The unique MAX100D power supply design uses transistor technology to produce a very smooth constant current DC output.

Air can be used as the primary plasma gas, providing low operating costs combined with high-speed performance. Cylinder air or shop air is acceptable as long as it is free of moisture, oil, and particulate matter contamination. For better cut quality on metals such as stainless steel, aluminum, and other non-ferrous materials, use either nitrogen, argon/hydrogen (Hypertherm recommends a mixture of 35% hydrogen and 65% argon), or a mixture of argon/hydrogen and nitrogen as the plasma gas. Air, nitrogen, and carbon dioxide are the shield gases that can be used.

In addition to cutting, the MAX100D can be used for plasma arc gouging. Both mechanized and hand gouging capabilities are provided. Air and H35 are the plasma gases for the gouging application. When H35 is used as the plasma gas, high gouging efficiency is achieved. Air gouging has lower efficiency but is economical on gas consumption.
