Electrode PT31 Long

The PT31 Long Electrode is an essential high-performance consumable engineered for the South African automotive, security, and light-industrial sectors. Designed specifically for the PT31 (LG40) air-cooled plasma torch, this extended variant is the primary choice for operators who require additional visibility and reach. While the "Short" version is the general-purpose standard, the Long Electrode (paired with a Long Nozzle) allows for precision cutting in tight corners, deep channels, and along high-profile templates where a standard torch head might be too bulky.

Key Performance Features

• Extended Reach Profile: The elongated design provides a superior line-of-sight for the operator, making it the go-to choice for following intricate patterns or stencils in sheet metal.
• Premium Hafnium Insert: Features a high-quality center-point for consistent arc ignition and a significantly longer service life compared to standard zirconium-core electrodes.
• Rapid-Cooling Copper Body: Manufactured from high-purity electrolytic copper to dissipate heat quickly, protecting the internal torch components during continuous 40A–50A cutting.
• Precision-Matched Alignment: Specifically calibrated to work in perfect concentricity with the PT31 Long Nozzle, ensuring a focused, high-velocity plasma jet for dross-free edges.

Ideal Applications

• Automotive Customization & Repair: The industry standard for cutting out rusted floor pans, trimming exhaust brackets, and modifying chassis components in restricted spaces.
• Security Gate & Metal Art: Perfect for hand-cutting decorative scrolls, intricate company logos, and custom patterns in 1.6mm to 4.0mm plate.
• Agricultural Maintenance: Ideal for reaching into the corners of grain bins, trailers, and harvester components to remove damaged sections.
• HVAC & Sheet Metal Ducting: Provides the clearance needed to cut through pre-formed flanges and complex ducting joints where a standard tip cannot reach.

Product Benefits

• Superior Operator Visibility: The extra length keeps the torch body further from the cut zone, allowing the welder to see exactly where the arc is traveling.
• Clean, Narrow Kerf: By maintaining a stable, focused plasma stream, this electrode minimizes heat-distortion on thin-gauge materials.
• Universal LG40/PT31 Fitment: Fully compatible with most South African inverter plasma cutters (30A–50A) utilizing the standard PT31 torch system.

Pro Tip: To maximize the life of your PT31 Long Electrode, always use it in combination with a Long Nozzle (Tip). Using a long electrode with a short nozzle will damage your torch head immediately. For the cleanest possible cut on 3.0mm mild steel, maintain a 1.5mm standoff distance from the plate; dragging the tip directly on the metal will cause "double-arcing" and significantly shorten the life of your consumables.
