Ultima-TIG-Cut Combined Wet Grinder and Cutter Units

Ultima-TIG-Cut units combine wet grinding and precise cutting of tungsten electrodes in one machine. The integrated cutting module cuts electrodes to exact length without splitting or thermal damage. Grinding and cutting are executed without removing the electrode from its holder.

Electrode diameter 0.8 to 4.0 mm with precise cutoff lengths down to 8 mm
Variable grinding angle from 7.5° to 90° with millimeter cutting length scale
Sealed wet chamber with disposable liquid container for safe waste disposal
High efficiency 280 W drive motor with ergonomic manual cutting handle

Ultima-TIG-S Heavy-Duty Wet Grinders for Electrodes up to 8 mm

Ultima-TIG-S heavy-duty grinders are engineered for wet grinding electrodes from 1.0 mm to 8.0 mm. Reinforced spindle design and specialized collets deliver uniform tip geometry on thick rods. The unit is widely used in mechanized plasma cutting, orbital and heavy-gauge TIG welding.

Electrode diameter capacity from 1.0 to 8.0 mm with dedicated heavy-duty collets
Adjustable grinding angle from 7.5° to 90° with 90° tip flattening capability
Sealed wet grinding containment chamber with disposable EP770 liquid container
Robust 280 W motor providing high torque and 31 m/s diamond surface speed

Neutrix Portable Dry Grinders with Integrated Dust Filter

Neutrix handheld grinders weighing only 2.8 kg provide mobile dry grinding for electrodes up to 4.0 mm. An integrated replaceable class H12 filter completely traps hazardous tungsten grinding dust. An inspection cover allows continuous visual monitoring to prevent sparking and overheating.

Lightweight 2.8 kg body supplied in a rugged case for site and installation work
Integrated replaceable cartridge dust filter protecting user respiratory safety
Triple-track diamond disc setting effectively tripling service life before disc change
Grinds electrodes from 0.8 to 4.0 mm down to minimum lengths of 19 mm or 15 mm

AutoGrind Digital Modules and Truncator Tip Modules

AutoGrind Digital automated modules automate electrode rotation on Ultima-TIG series grinders. A digital timer guarantees repeatable grinding cycle times while eliminating wrist strain. The Truncator module safely flattens electrode tips in calibrated increments of 0.1 mm.

Automated motorized rotation of the electrode holder for uniform grinding
Digital cycle timer for standardized series preparation without operator fatigue
Full compatibility with Ultima-TIG and Ultima-TIG-Cut (S version for up to 8 mm)
Truncator add-on module for accurate tip truncation calibrated in 0.1 mm steps

Technical Advantages of Longitudinal Wet Grinding for Tungsten Electrodes

TIG and plasma arc stability directly depend on the surface finish and longitudinal geometry of the tungsten electrode tip. Inelco Grinders equipment ensures concentric longitudinal grinding where grinding lines run parallel to the electrode axis.

This orientation concentrates cathode electron emission into a tight, focused arc column, eliminating arc wandering and ensuring uniform penetration in critical joint geometries.

Integrating EP770 cooling liquid in the Ultima-TIG series prevents thermal annealing and surface micro-fissuring of the tungsten matrix.

Compared to dry grinding, wet processing yields a super-smooth mirror finish, prevents premature electrode splitting under high currents and delivers up to five times more arc strikes between scheduled regrinds.

Comparative Evaluation of Stationary Ultima-TIG and Portable Neutrix Units

Stationary workshop installations and orbital tube welding cells benefit most from Ultima-TIG and Ultima-TIG-Cut wet grinding platforms. Built with robust cast housings, stepless angle adjustments from 7.5° to 90° and sealed liquid dust containers, they guarantee clean room compliance.

The Cut model incorporates an abrasive diamond cutting blade, enabling precision cutoff lengths down to 8 mm without splitting.

In contrast, the Neutrix handheld unit weighing 2.8 kg is designed for mobile plant installation and construction sites.

Supplied in a heavy-duty carrying case, it incorporates an integrated Class H12 HEPA dust filter and an eccentric adjustment mechanism that exposes three separate diamond tracks on the disc, tripling operational life between replacements.

Economic Impact and Tungsten Waste Reduction in Industrial TIG Fabrication

Conventional offhand bench grinding typically wastes 2 to 5 mm of expensive tungsten alloy per regrind while creating inconsistent tip geometry.

Inelco Grinders uses precision stick-out gauges and concentric collets that shave away a precise 0.3 mm layer, cutting electrode consumption substantially across high-volume production facilities.

Environmental safety is central to Inelco design when handling thoriated (WT-20) or rare-earth doped electrodes.

Toxic airborne particles are completely contained within disposable liquid chambers or sealed filter elements, ensuring strict compliance with occupational health and safety standards in fabrication facilities.

Integrating AutoGrind Digital Automated Modules with Welding Cells

Automated robotic cells and mechanized longitudinal seam welders require repeatable electrode tip geometry across all production shifts.

Retrofitting the AutoGrind Digital module onto Ultima-TIG machines eliminates operator variability by automating electrode rotation at a steady rotational velocity and digital timer-controlled duration.

The optional Truncator accessory introduces calibrated tip flattening in 0.1 mm increments.

Flattening the electrode tip prevents sharp point melting under welding currents exceeding 200 A, preserving tip stability and preventing tungsten inclusion contamination in nuclear, aerospace and pharmaceutical piping welds.
