Shield 420168 Plasma Cutting Torch Consumables 45-65A fit 220975 420158 420169 Hypertherm powermax125

1. Product Identification & Critical Correction

• Hypertherm Part Number: 420168

• Actual Name: Electrode, 45A/65A

• This is NOT a Shield. The description is fundamentally incorrect. Part number 420168 is an electrode, which is the central, internal consumable that generates the plasma arc.

Primary Function: The electrode is the cathode in the plasma circuit. Its hafnium emitter is the point from which the arc is initiated and sustained. It is a primary wear item.

2. Key Specifications

• Amperage Rating: Rated for use at 45 Amps and 65 Amps.

• Key Component: The emitter is made of hafnium, which has a high melting point and is consumed slowly during the cutting process.

• Compatible Systems: This electrode is designed for Hypertherm Powermax85 and Powermax105 systems.

• It is NOT a standard part for the Powermax125.

3. Clarification of Stated Compatibility ("fit 220975 420158 420169 Hypertherm powermax125")

This compatibility list is highly problematic and contains a mix of incorrect and partially correct associations.

1. With "Shield" 420168: As established, this part is an electrode, not a shield. Therefore, any claim of it being a shield that "fits" with other parts is invalid.

2. With Part 220975:

• 220975 is a Swirl Ring for the Powermax85/105.

• This is correct. Electrode 420168 and Swirl Ring 220975 are compatible as they are both from the Powermax85/105 consumable system.

3. With Nozzles 420158 (45A) & 420169 (65A):

• This is a critical ERROR.

• Nozzle 420158 (45A) and Nozzle 420169 (65A) are designed for the Powermax125 torch.

• Electrode 420168 is for the Powermax85/105.

• Mixing a Powermax85/105 electrode with a Powermax125 nozzle will result in improper alignment, catastrophic consumable failure, and terrible cut quality. The parts are from different torch platforms and are not interchangeable.

4. With "Hypertherm Powermax125":

• This is misleading. While a Powermax125 machine can be fitted with a Powermax85/105 torch (as a lighter-weight option), the consumables are not cross-compatible.

• If your system has a Powermax125 torch, you must use Powermax125 consumables (e.g., electrode 220779).

• If your system has a Powermax85/105 torch, you must use Powermax85/105 consumables.

4. Correct Consumable Sets & Compatibility for Electrode 420168

For Powermax85 / Powermax105 systems, the correct consumable sets are:

• Shielded Consumable Set (65A): Part Number 220995

• Includes: Electrode (420168), Nozzle (420169 would be incorrect; the correct 65A nozzle is 220788), Swirl Ring (220975), Retaining Cap (220976), Shield Cup (220974).

• FineCut Consumable Set (45A): Part Number 220945

• Includes: FineCut Electrode, FineCut Nozzle (420158 is correct here), Swirl Ring, Retaining Cap, and FineCut Shield.

5. The Correct Shield for Your Stated Parts

If you are looking for the Shield that works with nozzles 420158 and 420169 for a Powermax125, you need one of two parts:

1. For 65A Drag Cutting (with nozzle 420169):

• Shield Part Number: 420172

• This is the drag shield used in set 220971.

2. For 45A FineCut Cutting (with nozzle 420158):

• Shield Part Number: 220760

• This is the FineCut shield used in sets like 220943.

6. Consequences of Using the Wrong Parts

Using Electrode 420168 with Powermax125 nozzles (420158, 420169) will cause:

• Misalignment: The electrode and nozzle bores will not be concentric.

• Unstable Arc: The plasma arc will be skewed and weak.

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

• Instant Consumable Destruction: The misdirected arc will violently erode the nozzle and the electrode, destroying them within seconds or minutes.
