CNC plasma equipment is capable of multi-axis cutting of thick material, allowing opportunit ies for complex welding seams on CNC welding equipment that is not possible otherwise. For thinner material cutting, plasma cutting is being progressively replaced by laser cutting, due mainly to the laser cutter's superior hole-cutting abilities. A specialized use of CNC Plasma Cutters has been in the HVAC industry. Software will process information on ductwork and create flat patterns to be cut on the cutting table by the plasma torch. This technology has enormously increased productivity within the industry since its introduction inthe early 1980s. In the past decade plasma torch manufacturers have engineered new models with a smaller nozzle and a thinner plasma arc. This allows nearlaser quality on plasma cut edges. Several manufacturers have combined precision CNC control with these torches to allow fabricators to produce parts that require little or no finishing.

Coatec India is offering ten models of plasma cutting. The CNC system remains the same in all of these models. The variation is in the plasma source which starts from CutMaster (four models), AutoCut (three models) and Ultracut (three models). Further Water mist shielding is offered for cleaner and corrosion free cuts.

Reliability

Superior Warranty
Thermal Dynamics Automated Plasma Cutting systems carry a TWO year warranty – unmatched in the industry. A clear sign of the quality that is delivered to the customer.
Thermal Dynamics’ XT™-300 warranty covers components and service for a full 1 year period.

XT™ Torch Technology
Unique ‘Keyless’ Consumables Cartridge
The unique Consumables Cartridge houses consumable parts only, no built-in head/torch body to drive replacement costs up. Changing cartridges is fast and easy – a couple of twists and the unique ‘rapid engagement’ retaining collar threads release the cartridge. Down-time is reduced to minutes and one can change from one process to another or from one application to another quickly and easily.

No Tools Required
Unlike other torches, no tools are required to change either the torch consumables or major components in the Torch Head.

‘Leakless’ Torch Head Design
Coolant doesn’t drip from the torch head when the consumables cartridge is removed from the torch head. Prevents air from entering the system and becoming trapped in the leads.

Self-centring Components
Consumable parts and torch body are precisely engineered to lock into place for absolute alignment and remain positioned cut after cut. Independently-aligned tip and electrode assures accurate re-centring of the consumable cartridge after each parts change.

Precision Cuts on all Metals
The XT-300’s dual gas technology provides the highest arc density plasma stream in the industry for precision cuts on stainless steel, mild steel, aluminium and other non-ferrous materials. Choices for plasma gas include O2, N2-O2, Ar-H2-N2, or Air and shield gas choices include N2-O2, N2, Air-CH4 or Air.

Relaxed Cutting Parameters
With the XT-300 the operating window permits a +/- 30% travel speed variance which means one will get great cuts more often and less wasted material and time.

Less critical standoff height
Wider ‘Operating Window’ for dross-free cutting

The XTremeLife technology delivers the parts life and cut quality on mild steel with O2 plasma that the high-end customer expects. Unrivalled cut quality from gauge (0.5mm) to 1½" (40mm) material with the widest range of consumables in the market.

Bevel angles less than 3°
Square cut face with minimal top edge rounding
Smooth cut edge surface
Virtually dross-free parameter window up to 1½" (40mm)
Consistent cut quality over entire parts life
Water Mist Secondary (WMS®) For Non-Ferrous Materials

WMS delivers excellent non-ferrous cut quality and low cost of operation by using N2 as plasma gas and ordinary tap water as the secondary. A reducing atmosphere is produced in the cut by the release of hydrogen from the secondary water. The reducing atmosphere decreases oxidation on the cut face surface. WMS is recommended for materials up to 1" (25mm) thick.

The WMS process uses nitrogen as the plasma gas while water is used as the secondary gas (shield gas). The water in the torch is divided into its principal components (hydrogen and oxygen) during the cutting process. The hydrogen creates a reduced atmosphere in the cutting zone, isolating it from contaminating elements, and producing a clean, dross free and oxide-free cut surface. The majority of the water used during the process (from 4 to 8 GPH (0.25 to 0.5 l/min) is converted to principal components (gas) and thereby does not require disposal.
