Heavy-duty equipment engineered for continuous 24/7 duty cycles, extreme arc stability, and precision thermal processing across Czech industrial hubs.
The LGK Air Plasma Cutter Series 200 represents a monumental advancement in thermal arc cutting technology, engineered specifically for high-intensity industrial manufacturing ecosystems like those found across the Czech Republic (including major metalworking complexes in Central Bohemia, Moravia-Silesia, and the South Moravian Region). Powered by high-frequency soft-switching Dual-IGBT (Insulated Gate Bipolar Transistor) inverter modules, the LGK-200 system transforms standard compressed air into an ionized plasma jet exceeding temperatures of 15,000°C. This extreme kinetic and thermal energy constricts through precision-engineered copper-hafnium nozzle orifices to deliver instantaneous, dross-free severance on conductive metals.
Compared to conventional oxy-fuel gas cutting systems, the LGK Series 200 eliminates the operational hazards, logistics expenses, and thermal deformation associated with acetylene or propane storage. By utilizing compressed air as both the plasma gas and cooling medium, Czech fabricators achieve an exceptional reduction in per-meter cutting cost while drastically boosting throughput on carbon steel, structural alloy, stainless steel (AISI 304/316), and aluminum plate processing.

Targeted solutions engineered for the specific metallurgical, automotive, machinery, and structural requirements of Czech manufacturing hubs.
In the automotive manufacturing heartlands of Central Bohemia, speed and edge quality are vital. The LGK Series 200 integrated into automated 3D gantry units provides rapid blanking of high-strength structural steel chassis, custom brackets, and stainless exhaust components. The low heat-affected zone (HAZ) prevents structural warping in thin-to-medium sheet metals.
Czech Republic’s world-renowned machine tool and heavy equipment sectors require deep penetration beveling and thick plate profile severance. The LGK-200 cuts carbon steel plates up to 40mm thick with clean perpendicular edges, drastically reducing secondary grinding hours prior to robotized multi-pass groove welding.
In Moravia-Silesia’s steel mill operations and heavy scrap processing yards, equipment must endure relentless heat, dust, and continuous operation. Featuring IP23S environmental protection and heavy duty thermal overload sensors, the LGK Series 200 handles continuous 200-Amp manual severance of heavy steel beams, structural pipes, and scrap plates.
Fabricating passenger train frames, locomotive bogies, and tram bodies requires cutting high-alloy stainless steel and aluminum armor plates without dross buildup. The LGK-200’s pilot arc stability allows clean cutting of non-ferrous metals, assisting Czech railway equipment manufacturers in meeting EN 15085 rail welding standards.
Agricultural equipment fabricators in the Vysočina region rely on LGK Series 200 CNC table integration for rapid cutting of wear-resistant steel plates (such as Hardox 400/500). High arc voltage retention enables high-speed nesting of plow components, grain silo frames, and tractor hitch structures.
Energy component fabricators in Pardubice and Ústí nad Labem utilize LGK-200 plasma cutting torches attached to pipe-beveling tractors. Precision bevel preparation on pressure vessel shells and thick-walled pipes ensures compliance with strict European Pressure Equipment Directives (PED 2014/68/EU).
The industrial sector in the Czech Republic is currently experiencing a massive technological shift driven by the European Union Green Deal, escalating grid energy prices, and the national "Průmysl 4.0" (Industry 4.0) initiative. Manufacturing executives and welding engineers across Prague, Brno, and Ostrava are actively replacing legacy transformer equipment with high-efficiency inverter plasma technologies.
1. Shift from Costly Mixed Gases to Clean Compressed Air Systems: Historically, precision plasma cutting required expensive pure Nitrogen, Argon, or Oxygen gas supplies. The LGK Series 200 optimizes compressed air ionization through internal multi-stage air filtration, enabling Czech workshops to cut costs by over 65% per operational shift while satisfying strict environmental emissions guidelines.
2. Integration with Automated CNC Workcells & Robotics: As labor shortages affect Central European fabrication yards, demand for CNC plasma tables (such as Czech-made Vanad and Pierce control systems) has surged. The LGK-200 is engineered with dedicated CNC interface ports (Arc Transfer Signal, Arc Voltage Divider 1:50 / 1:20, and Remote Torch Switch) allowing effortless plug-and-play synchronization with automated cutting tables and 6-axis robotic arms.
3. Energy Efficiency & Grid Power Factor Compliance: Power quality is strictly monitored across Czech industrial parks. The LGK Series 200 incorporates active Power Factor Correction (PFC) architecture, maintaining a power factor >0.93. This reduces reactive power losses, minimizes harmonic distortion on the 400V 50Hz factory grid, and ensures compliance with ČSN EN 61000-3-12 electromagnetic standards.
Established in 1980 by Mr. Parag Mashruwala in the major industrial corridor of GIDC Vatva, Ahmedabad, India, Parag Electrodes Agencies Pvt. Ltd. (Paragweld) has evolved over 44+ years into a premier global manufacturer and exporter of heavy-duty welding machines, air plasma cutters, submerged arc systems, and specialized consumables.
Our manufacturing facility operates under rigorous ISO 9001:2015 Quality Management Systems. Every unit in the LGK Air Plasma Cutter Series 200 undergoes stringently documented quality control protocols prior to export dispatch:
With a established B2B export network serving machinery importers, industrial distributors, and structural engineering firms across Central Europe, Paragweld offers flexible Incoterms (FOB, CIF, DDP to Prague/Koper ports), complete OEM customization (custom branding, voltage tailoring, special torch lengths), and guaranteed spare parts availability for 10+ years.
Technical, regulatory, and procurement inquiries answered for Czech industrial buyers and welding engineers.
The LGK Air Plasma Cutter Series 200 is built for standard European 3-phase power supply (400V AC ±15%, 50/60Hz). It requires a dedicated 63A 3-phase circuit breaker (Type C or D industrial trip curve) and a minimum grid power supply capacity of 35 kVA for uncompromised continuous 200A cutting.
Yes. The LGK-200 features factory-installed CNC signal connection ports located on the rear panel. It outputs raw or divided arc voltage signals (1:50 divider default) for automated Torch Height Control (THC), along with Arc Transfer "OK to Move" dry contact relay signals compatible with all standard CNC motion controllers.
The machine requires clean, dry, oil-free compressed air at a operating pressure of 0.6 to 0.8 MPa (6.0 to 8.0 Bar) with a continuous flow volume of at least 300 Liters per minute. We strongly recommend installing a 2-stage air dryer and oil-water filter separator prior to the machine inlet to maximize torch electrode and nozzle life.
Paragweld LGK series cutters fully comply with European Union Low Voltage Directive (LVD) 2014/35/EU and Electromagnetic Compatibility (EMC) Directive 2014/30/EU. They are certified under EN 60974-1 (Safety requirements for arc welding equipment) and EN 60974-10 (EMC Class A standards), carrying valid CE marking for customs clearance in Czech Republic.
Under standard operational conditions with dry compressed air, high-quality Hafnium-embedded electrodes and heavy-duty copper nozzles yield approximately 600 to 900 cut starts (or 3 to 5 hours of continuous arc-on time). The HF non-contact pilot arc system significantly minimizes mechanical wear during arc initiation.
While fiber lasers excel in thin sheet precision under 6mm, their initial capital investment ($100k-$300k+) is prohibitive for many fabricators. The LGK-200 air plasma cutter provides an optimal ROI for plates between 6mm and 40mm thick, operating at a fraction of the machinery investment cost while maintaining excellent severance speed on structural steel.
We supply sea freight containers via Hamburg or Koper ports with typical transit times of 28 to 35 days, or express air cargo for urgent spare parts and compact inverter machines (5-7 days to Vaclav Havel Airport Prague). All shipments are packed in seaworthy reinforced wooden crates with vapor corrosion inhibitor (VCI) protective lining.
Paragweld supplies a 12-month comprehensive factory warranty on main power transformers, IGBT inverter modules, and main PCB control boards. Replacement parts, alternative torch leads (straight CNC or hand torches), and consumable packs are stocked for rapid global dispatch to minimize downtime.
