Air / Gas Plasma Cutting Machines

Applications: Can cut all electrically conductive metals like S.S, C.S, Copper, Aluminium, Inconel, Titanium etc. Metals like Stainless Steel & Aluminium can not be cut by Oxy - Acetylene as the metal reacts with Oxygen during cutting to form oxides whose melting point is higher than the temp. of the Oxy-Acetylene flame. Plasma Arc temp. are in excess of 20,000 oC with the high velocity flow which blast through all metals with a very clean finish at high speed.

  • Cut expanded metal, painted or rusted plates.
  • Nonlinear cuts and bevelling for edge preperation before welding
  • Gouging can be performed just by changeing the nozzle.
  • Hand held and mechanized options available.
  • Air plasma cutting upto 70 mm / Gas plasma cutting upto 150mm.

Description: Consist of Power source with controls, Water recirculating system if required and a well designed Torch. The basic principle is that the arc formed between the electrode and the work piece is constricted by a fine bore, copper nozzle. This increases the temperature and velocity of the plasma emanating from the nozzle. The temperature of the plasma is in excess of 20 000°C and the velocity can approach the speed of sound. When used for cutting, the plasma gas flow is increased so that the deeply penetrating plasma jet cuts through the material and molten material is removed in the efflux plasma.

Features :

  • Optimised design of fully copper wound air cooled transformer with high quality CRGO laminations to ensure low power consumption at 100% duty cycle.
  • Power factor correction capacitors ensures Power Factor of 0.85 - 0.9% ensuring lowest power consumption.
  • Power controlled in steps in high capacity machines for extended power saving.
  • High open circuit voltage to accommodate easy arc striking. Fully protected power source against voltage fluctuation & overload added with complete safety interlocking for torch protection against air and water failure.
  • Easy to operate and maintain torch head for operator's convenience.
  • Highly improved torch design offers higher cutting capacity at low power output.
  • Torch design guarantees long life of consumables viz. electrode and nozzle.
  • Almost vertical, dross free cuts with minimum kerf width.
  • Standard Torch cable length of 7 meters with option to extend upto 30 meters.
  • Robust design with powder coated chassis & panels ensures long life in site conditions also.

* To cut 150mm we are using 2 ARC-CUT 100 3S in parallel .
Clean Cut: Absolute dross free and smooth cut with 90o on one cut face max 2o bevel on other.
Parting Cut Max cutting capacity where some dross will be generated and grinding will be required, cut will be tapered on both plates.
