0558009302 - ESAB PT-36 Water Injection Cup Body Replacement

Precision Engineering for High-Performance Plasma Cutting

The ESAB Cup Body WTR INJ PT-36 (0558009302) is a critical replacement component designed specifically for the PT-36 mechanized plasma cutting torch. As part of ESAB's advanced m3 Plasma systems, the PT-36 torch utilizes water injection technology to achieve superior cut quality, particularly on non-ferrous metals like stainless steel and aluminum. This cup body plays a pivotal role in housing the internal consumables and directing the water flow necessary for arc constriction.

In high-precision plasma cutting, the alignment and integrity of the torch head components are paramount. The Cup Body acts as the structural foundation for the nozzle and electrode assembly, ensuring that the plasma arc remains centered and stable. The "WTR INJ" designation indicates its specific design for water injection processes, where a swirl of water is used to constrict the plasma arc, increasing its energy density and temperature. This results in narrower kerfs, squarer edges, and faster cutting speeds compared to standard dry plasma cutting.

Manufactured to ESAB's exacting OEM standards, this cup body is built to withstand the extreme thermal cycles and high pressures associated with heavy-duty industrial cutting. Using non-genuine parts in a sophisticated system like the PT-36 can lead to coolant leaks, poor arc quality, or even damage to the torch head. By choosing the genuine 0558009302 Cup Body, operators ensure seamless compatibility and maintain the reliability of their automated cutting tables.

Key Technical Benefits

The design of this cup body incorporates precise fluid channels that manage the distribution of the water injection shield. This cooling mechanism not only improves the metallurgical quality of the cut edge but also significantly extends the life of the nozzle and electrode by reducing heat buildup. For fabrication shops relying on the PT-36 for continuous production, maintaining the condition of the cup body is essential for preventing costly downtime and ensuring consistent part tolerances.
