5-2986 - Thermal Arc PWH-3A / PWH-4A Introductory Spare Parts Kit

Thermal Arc 5-2986 Spare Parts Kit for PWH-3A/4A

The Thermal Arc 5-2986 is a specialized Introductory Spare Parts Kit designed specifically for the maintenance and operation of PWH-3A and PWH-4A plasma welding torches. In high-precision plasma welding environments, the condition of the torch consumables is paramount to maintaining arc stability, weld quality, and system longevity. This kit aggregates the most frequently replaced components into a single, organized package, allowing maintenance personnel and operators to perform quick changeovers and routine service without the delay of ordering individual part numbers.

As an OEM product from Thermal Arc (now part of the ESAB family), every component within the 5-2986 kit is manufactured to precise tolerances. The kit typically includes a selection of tungsten electrodes, centering sleeves, collets, and plasma tips (orifices) suitable for the amperage ranges standard to the PWH-3A and PWH-4A heads. Additionally, it often contains necessary maintenance tools such as a setting gauge for precise electrode setback adjustment and a pin wrench for disassembly. The inclusion of replacement O-rings ensures that the cooling and gas sealing integrity of the torch can be maintained during reassembly.

For industrial facilities utilizing automated plasma welding systems, inventory management of small consumables can be challenging. This introductory kit solves that problem by providing a baseline stock of critical items. It serves as an excellent starter package for new equipment installations or as a reliable backup inventory for existing production lines. By using genuine Thermal Arc parts, users ensure compatibility with the torch's liquid cooling system and gas distribution channels, preventing issues such as overheating or gas turbulence that can arise from ill-fitting aftermarket alternatives.
