Lincoln Electric Weld-Pak 45i Plasma DV K5420-1 is a dual-voltage handheld plasma cutter for metal fabrication, repair, farm, HVAC and autobody work. It supports cutting mild steel, stainless steel, aluminum and other documented conductive metals with an external compressed-air supply.
Key Features and Benefits
- 120 V or 230 V input supports the documented dual-voltage setup.
- A digital amperage display makes the selected cutting output visible.
- The included 13 ft cutting torch provides the handheld cutting connection.
- Touch-start arc initiation avoids a high-frequency starting system.
- Recommended cutting, maximum cutting and severance are separate ratings.

Applications and Compatibility
For conductive-metal cutting with the correct torch consumables. This is a plasma cutter, not a welding power source. The 230 V cutting figures must not be assumed on 120 V. Severance describes a different result and travel speed from recommended cutting.

Setup and Documentation
Use the exact machine-code operator manual to confirm the electrical circuit, compressed-air pressure and flow, and torch consumables before installation. Check those requirements against the machine nameplate and current operating instructions before connecting the supply. Follow the documented inspection and replacement procedure.
Frequently Asked Questions
Does it need an external air supply?
Yes. Connect a suitable compressed-air supply according to the exact operator instructions; a compressor is not listed as included.
Are both input plug options supplied?
The package lists a 230 V 6-50P input plug and a 120 V 5-15P adapter.
Is the 3/4 in figure the recommended cut?
No. The manufacturer separates 1/2 in recommended cutting from 3/4 in severance, with different travel speeds on the 230 V configuration.
Does it include a torch?
Yes. The exact package lists a 13 ft cutting torch assembly.
