CNC Plasma Cutting Machines — Gantry & Cantilever for Fabrication

Plasma cuts using a high-velocity ionised-gas jet at 20,000-30,000°C. It can cut any electrically conductive metal — mild steel, stainless steel, aluminium, copper, brass — and is the only cutting process that handles non-ferrous metals well. Oxy-fuel uses an oxygen-fuel-gas flame and only cuts ferrous metals (mild steel, low-alloy steel) by a chemical oxidation reaction. Plasma is faster on thinner sections (up to ~32 mm), produces a narrower kerf, and has a smaller heat-affected zone. Oxy-fuel is more economical for very thick mild steel (50-300 mm) and produces less noise and dust.

Yes, that's one of plasma's strengths. Mild steel: 5-50 mm depending on machine and plasma source. Stainless steel: typically 5-30 mm; cut quality drops above 25 mm. Aluminium: 5-25 mm; the cut surface is somewhat rougher than mild steel. For stainless and aluminium, nitrogen or compressed air plasma gas gives best edge quality (vs oxygen, which oxidises stainless and rejects clean cuts on aluminium). Our technical team helps with gas selection.

Pressure vessels and large structural work typically need 2 m × 6 m to 3 m × 12 m tables. Ship-block sub-assembly often uses 3 m × 12 m. Smaller fabrication shops doing plate work for buildings or industrial structures usually need 2 m × 6 m. Sheet-metal job shops doing AHU and stainless-equipment work usually fit on 1.5 m × 3 m. We'll do a pre-purchase site survey to recommend the right table size based on your typical job mix.

A 2 m × 6 m gantry plasma machine occupies roughly 4 m × 9 m of floor space (table + service access). Add 2-3 m clearance for plate handling. Power: 415 V 3-phase, typically 50-100 A depending on the plasma source rating (Hypertherm Powermax 105 = ~25 kW; 200 = ~50 kW). Compressed air or specialty gas (oxygen, nitrogen, argon-hydrogen) supply needed. We do a pre-installation site survey to confirm power and gas availability.

Yes. Ador Pugnax and Pugmax CNC machines are offered with native Ador plasma sources (cost-effective) or with Hypertherm Powermax sources (premium cut quality, longer consumable life, better automated piercing). Hypertherm-equipped machines are popular in shipyards and high-production shops where uptime and edge quality matter more than CapEx. We recommend the right combination during the pre-purchase consultation.

Plasma electrodes typically last 2-4 hours of arc-on time at full duty cycle (Hypertherm Powermax sources extend this to 4-8 hours with adaptive bench modes). Nozzles last roughly the same. Cost per cut depends on the part being cut, but for typical 16 mm structural-steel work, consumable cost is roughly ₹12-25 per metre of cut length. We supply original Ador and Hypertherm consumables from stock — typical refurbishment kit (electrodes, nozzles, swirl rings, retaining caps) is ₹3,500-8,500 depending on amperage rating.

Yes. Standard installation package: site survey, pre-delivery inspection, shipping & rigging, installation, commissioning, operator training (2-3 days), and acceptance testing at multiple thicknesses. After-sales: telephone & remote support included for 12 months; on-site service via our trained engineers. Annual maintenance contracts (AMC) available for production-critical installations — typical AMC includes 4 quarterly visits plus consumables credit.
