Hypertherm :

Hypertherm® XPR170® and XPR300®

XPR advances HyDefinition® cut quality by blending new technology with refined processes for next generation, X-Definition cutting on mild steel, stainless steel and aluminum using the same cutting

The XPR system increases cut speed, dramatically improves productivity and slashes operating costs. New ease-of-use features and engineered system optimization make XPR easier to run with minimal operator intervention and the same cutting consumables while also ensuring optimal performance and unmatched reliability.

KOIKE also boasts Hypertherm® True Hole® Technology certification. Bolt hole quality is delivered automatically without operator intervention allowing for precise cuts to exacting standards.


Hypertherm® XPR460®

The Hypertherm® XPR460®, the newest addition to the Hypertherm® XPR plasma systems family, offers the most consistent cut quality, thicker cutting capabilities, and faster cutting speeds in its class, all while maintaining the same consoles (Torch Connect and Gas Connect including Core, CorePlus, VWI, and OptiMix), hardware (torch and receptacle, standard leads, sleeves), and accessories (rotational sleeve, nozzle retaining cap, and shield retaining cap).

The XPR460@ delivers over 28% more output power (kW) than the HPR400XD®, allowing for mild steel piercing up to 2 1/2" and boasts significant reduction in operating costs by extending the life of consumables through Ramp Down Error Protection which prevents excessive arc stretch, shutting down system operations when consumable blowout is detected.

Ergonomic enhancements include a "double" negative lead with strain relief and a poka-yoked design, ensuring an installer-friendly setup. The work lead has also been extended to 35 meters (114.8 feet) to further ease installation.

Hypertherm® HPR400XD®

The Hypertherm® HPR System offer superior quality and consistency in cutting fine-feature parts, reducing the need for secondary operations. These systems boast long consumable life, quick consumable changes, dross-free edges, minimal angularity, and high reliability, maximizing productive “arc-on-time.”

Available in 130 to 800 amp options to meet diverse production demands.

Patented Hypertherm® PowerPierce® technology extends robust production pierce capability to 50 mm (2”) with 400 amps on mild steel and 75 mm (3”) with 800 amps on stainless steel and aluminum. Combined with a controlled motion process, the technology provides maximum stainless pierce capability up to 75 mm (3”) with 400 amps and 100 mm (4”) with 800 amps.




KJELLBERG® SMART FOCUS 200®, 300®, 400®

For more than 60 years, Kjellberg has been one of the global market leaders supplying high-quality, high-precision plasma cutting systems and consumables. And now this German-engineered plasma cutting technology is available and supported in North America.

Kjellberg’s complete portfolio of innovative and adaptable cutting technology helps metal fabricators to make the most precise cuts with its standardized components, offering intelligent and simple-to-use systems for a high speed, low cosumption cutting solution.

Features Kjellberg’s Contour Cut Technology
Performs small contours, narrow webs and bolt holes with a diameter to material thickness ratio of 1:1, resulting in excellent quality parts cut with mild steel.

This head enables sophisticated 3D bevel cutting, facilitating precise angle cuts in multiple dimensions, performing A, V, X, Y, and K bevels.

The 3D-X design incorporates a helical rack and pinion lifter for fast, smooth, and precise motion, that delivers smaller corner loops and better hazard clearance at Y-axis 45 degrees.

Its advanced features ensure efficiency and precision, with one-touch homing and alignment capabilities, integrated torch breakaway, and concealed A/B axis motor and encoder cables.


Allows for plasma beveling in the rail axis with non-contour
mechanical adjustment from +/- 0 to 45°.



With a 12” (340.8 mm) lifter travel and a programmable lifter speed of 1,000 IPM, the Koike THC ensures swift and accurate adjustments during the cutting process.

Its adjustable stroke retract between cuts enhances operational efficiency, while dynamic positioning capabilities further optimize performance, enabling seamless adaptation to varying cutting conditions for consistent results.

OXY-Fuel Equipment Options :

All stations are controlled from the Operator console and can hold
up to 8 torches.

Includes three cutting tips and standard 500L Koike torch*, offering
plate cutting from 1/8” to 12” (3mm to 300mm) thick.

*Optional Manual Bevel Station Available for Koike 500L Torch



Delivers precise control of oxy-fuel operations, featuring the Cutting
Torch, Gas Control, Flame Ignition, Height Sensing, Lifter, and Bevel operations all in one package requiring only connections for oxygen
and fuel gas.

Additionally, all comprehensive database systems are implemented
directly into the CNC Console, automating the entire process from
ignition, preheating, piercing, and cutting, eliminating the need for
additional cutting control hardware.

Advanced features include flash back and slag detection to enhance
torch longevity, and allows close to edge cuts and kerfs with minimal
torch-to-torch distance.


Featuring Koike-designed Proportional Valves, this closed-loop system automates the setting and regulation of cutting oxygen, preheat oxygen,
and fuel gas pressures for oxy-fuel cutting while continuously monitoring
and maintaining precise gas flow and pressure.

Operators can select the tip size and plate thickness, and the system automatically adjusts the gas pressures from the Katana CNC.


HI-LO Oxy-Fuel Gas System with Auto Ease-On:

HI-LO system initiates faster preheating of plate, delivering superior cutting quality and precise piercing on thicker plate. Features auto ease-on pierce control for cut oxygen.
