20382 - Hypertherm 020382 Extended Electrode for Powermax 350 & 380

Technical Overview of the Hypertherm 020382 Extended Electrode

The Hypertherm 020382 is a specialized extended electrode designed specifically for low-amperage plasma cutting applications using the Powermax350 and Powermax380 systems. Engineered to operate at 25 Amps, this consumable is a critical component of the plasma torch assembly, responsible for conducting the current to the arc and emitting the plasma jet. It is fully compatible with the PAC110 and PAC110T handheld torches found on these legacy Hypertherm machines.

As an extended electrode, the 020382 features a longer physical profile than standard electrodes. This geometric difference serves a functional purpose: it projects the arc initiation point further away from the torch body. This design is particularly advantageous when performing drag cutting or when the operator requires enhanced visibility of the cut line. The extended reach also facilitates cutting in confined spaces, corners, or complex geometries where a standard, shorter nozzle and electrode setup might be obstructed by the torch head itself.

Constructed from high-grade copper with a precisely inserted hafnium emitter, this OEM part ensures consistent electrical conductivity and thermal management. The hafnium insert is the focal point of the arc; its quality directly influences the stability of the plasma stream and the lifespan of the consumable. Using genuine Hypertherm consumables like the 020382 guarantees that the gas flow dynamics within the PAC110/PAC110T torches are maintained according to factory specifications, preventing issues such as premature torch wear, unstable arcs, or poor cut quality.

Regular inspection of the electrode is necessary for optimal system performance. The electrode should be replaced when the hafnium pit depth exceeds approximately 1mm (0.040 inches) to prevent damage to the nozzle and torch head. This part is often used in conjunction with the extended nozzle (part number 020381) to complete the extended consumable stack-up.
