45A Nozzle 420158 ,65A Nozzle 420169 Plasma Cutting Torch Consumables compatible parts for Hyperthem fit 220971 420168

1. Product Identification & Overview

• Hypertherm Part Number (45A): 420158

• Hypertherm Part Number (65A): 420169

• Common Name: Nozzle, Tip.

• Primary Function: To constrict and focus the plasma arc, determining its density, energy, and ultimate cut quality. The orifice size is directly related to the amperage rating.

2. Key Specifications & Differences

3. Clarification of Compatibility with "fit 220971 420168"

This is a critical point of confusion. Here is the precise compatibility breakdown:

1. With Set 220971 (Drag & Cut Set for Powermax125):

• 65A Nozzle (420169): This nozzle is a direct component of the 220971 set. It is the correct and intended nozzle for this 65A drag-cutting package.

• 45A Nozzle (420158): This nozzle is NOT part of set 220971. It is part of the FineCut consumable system and is not compatible with the other components in the 220971 set.

2. With Part 420168 (Electrode for Powermax85/105):

• This is a common but incorrect assumption driven by online marketplaces.

• Part 420168 is a 45A/65A electrode specifically designed for the Powermax85 and Powermax105 systems.

• Neither nozzle 420158 nor 420169 is designed to be used with electrode 420168.

• Using a Powermax125 nozzle with a Powermax105 electrode will result in poor alignment, terrible cut quality, and rapid consumable failure.

4. Correct Consumable Sets & Compatibility

To use these nozzles correctly, they must be paired with their matching components from the same product family.

For the 65A Nozzle (420169):

• Correct System: Hypertherm Powermax125.

• Correct Consumable Set: 220971 (Drag & Cut Set) or the components it contains.

• Must be used with:

• Electrode: 220779

• Swirl Ring: 220777

• Retaining Cap: 420156

• Shield: 420172

For the 45A Nozzle (420158):

• Correct System: Hypertherm Powermax125 (and also Powermax85/105, with different retaining caps).

• Correct Consumable Set: This is a FineCut nozzle. It must be used as part of a FineCut set, such as 220943 (for the Powermax125).

• Must be used with:

• Electrode: 220759 (FineCut electrode for Powermax125)

• Shield: 220760 (FineCut shield for Powermax125)

• Retaining Cap: The FineCut retaining cap specific to your machine (e.g., 220758 for Powermax125).

5. Consequences of Mixing Incompatible Parts

Mixing consumables from different systems (e.g., Powermax125 nozzles with Powermax105 electrodes) or different sets (e.g., FineCut nozzles with standard parts) will cause:

• Poor Arc Alignment: The electrode and nozzle will not be concentric, causing a skewed, weak arc.

• Terrible Cut Quality: Severe bevel, dross, and rough edges.

• Shortened Consumable Life: The misaligned arc will rapidly and unevenly erode the electrode and nozzle, often destroying them in minutes.

• Torch Damage: In severe cases, it can lead to double-arcing, which can damage the swirl ring, retaining cap, and even the torch body.

6. How to Identify the Correct Parts

• Always refer to the official Hypertherm manual or parts guide for your specific model (e.g., Powermax125) and the desired process (e.g., 65A Drag Cutting, FineCut).

• Use complete, pre-defined sets (like 220971) if you are unsure. This guarantees compatibility.

• Be cautious of generic online descriptions like "fit for...". They often list many part numbers to attract searches, leading to the compatibility confusion seen with "fit 220971 420168".

Summary:

• The 65A Nozzle (420169) is compatible with set 220971 for the Powermax125.

• The 45A Nozzle (420158) is a FineCut component for the Powermax125 and is not compatible with set 220971.

• Neither nozzle is compatible with electrode 420168, which is for Powermax85/105 systems.

Always match consumables from the same official Hypertherm set for your specific plasma system to ensure performance, quality, and torch safety.
