IMPORTANT COMPATIBILITY NOTE: Despite having “220941” as the part number, this nozzle does NOT fit PowerMax 45 machines. It’s designed for PowerMax 65/85/105 systems running at 45 amps.
When You Need the 220941
Perfect for 45A Applications: This nozzle really shines when you’re running PowerMax 65, 85, or 105 systems at exactly 45 amps. It’s designed to give you the best possible cut quality at this specific amperage, particularly for drag cutting.
Ideal Cutting Scenarios:
- Medium plate cutting: 3/8″ to 5/8″ steel at 45A
- Hand torch work: Drag cutting applications
- Precision fabrication: When 45A gives the right balance of speed and quality
- Portable cutting: Hand torch work in the field
Not the Right Choice If:
- You have a PowerMax 45 (it won’t fit)
- You mostly cut at higher amperages (use appropriate higher-amp nozzle)
- You do mostly mechanized cutting (consider mechanized nozzles)
- You rarely use 45A settings
Real Performance at 45A
What This Nozzle Does Best: At 45 amps on compatible PowerMax systems, the 220941 delivers excellent cut quality with minimal dross. The Conical Flow design concentrates the arc energy for clean cuts and good piercing capability.
Material Performance:
- Mild Steel (1/4″ to 5/8″): Excellent edge quality and cutting speed
- Stainless Steel (1/8″ to 1/2″): Good results with proper technique
- Aluminum (1/8″ to 3/8″): Clean cuts with appropriate gas settings
Honest Performance Expectations:
- Excellent at 45A: Designed specifically for this amperage
- Good at 30-40A: Still performs well slightly below rated amperage
- Poor above 45A: Don’t exceed rated capacity
- Drag cutting optimized: Best results when tip touches material
Installation & Drag Cutting Tips
Standard Installation:
- Power down plasma system completely
- Allow torch to cool if recently used
- Remove old nozzle counterclockwise
- Thread in new 220941 nozzle hand-tight
- Snug with appropriate wrench (don’t overtighten)
- Set system to 45A for optimal performance
Drag Cutting Technique:
- Light contact: Let nozzle tip lightly touch the material
- Steady travel: Maintain consistent cutting speed
- Proper angle: Keep torch perpendicular to work surface
- Clean starts: Begin cuts away from finished edges when possible
Maximizing Nozzle Life:
- Stay at 45A: Don’t exceed the designed amperage
- Clean material: Remove paint, rust, and dirt before cutting
- Proper gas flow: Ensure adequate gas pressure and flow
- Regular inspection: Check for wear and replace when needed
Compatible System Setup
PowerMax 65 Setup:
- Amperage: Set to 45A for optimal performance
- Gas: Use appropriate cutting gas for material
- Consumables: Pair with 220842 electrode and appropriate shield
PowerMax 85 Setup:
- Amperage: Dial down to 45A (don’t use full 85A capacity)
- Benefits: More stable arc due to larger power supply
- Applications: Good for precision work requiring 45A performance
PowerMax 105 Setup:
- Amperage: Set to 45A (significantly below full capacity)
- Advantages: Excellent arc stability and consistent performance
- Use Case: When you need the precision of 45A cutting
Essential Consumable Partners:
- Electrode 220842: Standard pairing for most applications
- Electrode 220777: CopperPlus for extended life on thin materials
- Shield 220817: Basic shield for general cutting
- Swirl Ring: Use appropriate swirl ring for your system
Troubleshooting Common Issues
Poor Cut Quality:
- Check amperage: Ensure system is set to 45A
- Verify compatibility: Confirm you’re using PowerMax 65/85/105
- Inspect nozzle: Look for wear or damage to orifice
- Gas flow: Check for proper gas pressure and flow
Short Nozzle Life:
- Amperage too high: Don’t exceed 45A rating
- Poor technique: Avoid gouging or excessive contact pressure
- Dirty material: Clean workpiece before cutting
- Wrong torch: Verify you’re using Duramax torch
Arc Starting Problems:
- Check electrode: May need replacement
- Gas issues: Verify proper gas flow
- Consumable alignment: Ensure proper assembly
- System settings: Confirm 45A amperage setting

Frequently Asked Questions
Q: Will this fit my PowerMax 45? A: No – despite the similar part number, 220941 does NOT fit PowerMax 45 machines. It’s for PowerMax 65/85/105 only.
Q: Can I use this nozzle at higher amperages? A: Don’t exceed 45A. It’s designed specifically for this amperage and will fail quickly if overdriven.
Q: What’s the difference between this and mechanized nozzles? A: This is optimized for drag cutting (hand torch). Mechanized nozzles are designed for standoff cutting.
Q: Why choose 45A when I have an 85A or 105A system? A: Sometimes 45A gives the best balance of cut quality and speed for your material thickness.
Q: How do I know when to replace this nozzle? A: Watch for poor cut quality, difficult piercing, or visible wear to the orifice opening.
