High Performance Cutting

• HD300W plasma cutting system cuts fine-feature parts with superior quality and consistency, eliminating the cost of secondary operations.

• The focused plasma arc for more powerful precision cutting up to 40mm on Mild Steel and 32mm on Stainless steel and Aluminum.

• With water spray cutting process, the stainless steel and aluminum cutting will be less warping and produce a small heat-affected zone.

Water Mist Secondary (WMS) Technology

During the cutting process, the water in the shield stream is divided into its principal components—hydrogen and oxygen. The hydrogen creates a reduced atmosphere in the cut zone, isolating it from contaminants at a much lower cost per metre than other cutting processes. Since it uses normal tap water, Water Mist Secondary also reduces production costs and keeps overall energy usage to a minimum.

Long Consumable Life & Fast Cutting Speed

Long Consumable Life

• 12mm mild steel；

• 200A Air/Air；

• 20s duration;

• The number of consumable starts can reach more than 500 times (ISO9013 Range 2).

Fast Cutting Speed

The cutting speed of dross free can reach 1600mm/min for 20mm mild steel.

Bevel Cutting Technology

Bevel Cutting Technology is a performance application for mild steel. Factory tested and easily implemented, it takes the guesswork out of the plasma bevel-cutting process. With Bevel Cutting Technology, setups for new jobs are quick and results are accurate and consistent.

• 1 iteration

• Using True Bevel

• Acceptable part and ready to start production

Refined Torch System

• Double air system torch;

• Nozzle cooling for increased electrode life and reduced operating costs;

• Work with TOPWELL high voltage power source to shift the cutting limitation.

* ISO 9013 is a standard that defines cut quality of thermally cut parts. The lower the range (range 1 is the lowest), the smaller the angle on the cut face. Cut angle in range 4 is better than in range 5.
