Top 3 Alternatives for Forney Plasma Cutters
Cutting Performance Across All Forney Models
The cutting performance of Forney plasma cutters varies based on the model and voltage input. Understanding these differences helps you choose the right machine for your projects.
The Easy Weld 20 P handles light duty work. It cuts sheet metal, thin plate, and light structural members. You get clean results on 1/4 inch mild steel without much effort. For anything thicker, the cut quality drops and the speed slows down.
The 40 P opens the door to heavier projects. On 230V, it pushes through 1/2 inch mild steel with smooth edges and minimal dross. On 120V, expect good performance up to 1/4 inch. The 40 amp output provides a noticeable speed advantage over the 20 P.
The 45 P PRO delivers the best results in the lineup. It cuts 7/8 inch steel cleanly at 10 inches per minute. For daily production cutting, this model saves significant time. The Forney Ignite Torch produces a tight, focused arc that improves edge quality.
Duty Cycle and Thermal Protection
Duty cycle is one of the most important specs to understand before you buy a plasma cutter. It tells you how long you can cut continuously within a 10 minute period.
The Easy Weld 20 P has a moderate duty cycle that supports short burst cutting. It is ideal for quick cuts on thin material. For extended cutting sessions, you will need to pause and let the machine cool down.
The Forney 40 P offers a 60% duty cycle at 40 amps on 230V. This means 6 minutes of continuous cutting followed by 4 minutes of rest. At 28 amps, it runs at 100% duty cycle, which means non stop cutting. This is useful for lighter work where full power is not needed.
The 45 P PRO provides even better endurance for professional use. Its higher capacity allows extended cutting sessions on thick material without frequent shutdowns.
Portability and Build Quality
Forney designs its plasma cutters with portability in mind. The Easy Weld 20 P weighs just 21.5 lbs. You can carry it with one hand. This makes it the best choice for mobile work and tight spaces.
The 40 P weighs slightly more but remains easy to transport. Its compact dimensions (12.375 x 18 x 7.375 inches) fit in truck beds and small work carts without trouble. The carry handle on top makes moving it between stations quick.
The 45 P PRO is the heaviest at approximately 43 lbs. It is still portable, especially on a welding cart. The scratch resistant cabinet holds up well in demanding shop conditions where tools and materials bump against it daily.
All Forney plasma cutters feature metal construction for durability. The internal components are well protected behind sturdy housings. Users report that these machines handle shop dust, heat, and daily use without premature failure.
Air Supply Requirements
Every plasma cutter needs compressed air to operate. Forney makes the air setup simple with built in regulators and moisture separators on their machines.
The Easy Weld 20 P requires a minimum of 1.5 CFM at 60 PSI. Most small shop compressors meet this requirement easily. You do not need an industrial grade compressor for this model.
The 40 P needs slightly more air flow to run at full capacity. A compressor delivering at least 4 to 5 CFM at 90 PSI works best for the 230V mode. On 120V, the air demands are lower since the output amperage is reduced.
The 45 P PRO has the highest air requirement due to its 45 amp output. A shop compressor with at least 6 CFM at 90 PSI is recommended for consistent performance. Insufficient air pressure causes inconsistent cuts and increased dross buildup.
Consumables and Replacement Parts
One of the biggest ongoing costs with any plasma cutter is consumable replacement. Forney keeps this process straightforward and affordable.
The Easy Weld 20 P uses the same consumable tips as the older Forney 302 and 303 models. Forney sells a 4 pack consumable kit (Model 85392) that includes 2 electrode nozzle tips and 2 cutting tips. These are available on Amazon and through hardware stores.
The 40 P uses IPT 40 torch consumables. These include electrodes, nozzle tips, shield cups, and swirl rings. A 13 piece consumable kit is available from Forney that covers all the parts you need for regular maintenance.
The 45 P PRO uses consumables specific to the Forney Ignite Torch. These are designed for longer life, which means you replace them less often. Forney sells electrode packs and tip sets through their website and Amazon.
Warranty Coverage Explained
Forney structures its warranty differently from many competitors. Instead of a single blanket warranty period, Forney breaks coverage down by component.
The full product warranty for material and workmanship defects covers 30 days. The plasma torch carries a 90 day warranty. This is relatively short compared to some brands that offer 1 year torch coverage.
Internal electrical components that require cover removal to access have a 3 year warranty. The transformer and rectifiers receive 5 year coverage. This tiered approach means the most expensive components have the longest protection.
Some users find this warranty structure a bit confusing. Pro Tool Reviews noted the same observation in their review. However, the 3 and 5 year coverage on critical internal parts provides meaningful peace of mind.
Generator Compatibility
Many users need to run their plasma cutter on generator power at remote locations. Forney designs all three models to be generator friendly, but there are specific requirements to follow.
The Easy Weld 20 P runs on a generator with at least 5,000 continuous watts. Since it only needs 120V input, most portable generators meet this standard. Make sure the generator output has less than 5% total harmonic distortion (THD).
The 40 P on 120V also needs a minimum of 5,000 continuous watts. To run it on 230V, plan for at least 10,000 continuous watts. This requires a larger, more expensive generator, but you get the full 40 amp output in return.
The 45 P PRO follows similar guidelines for 230V generator operation. A 10,000 watt continuous rated generator with clean power output is recommended. Avoid generators with eco mode or low idle fuel saver features unless you can bypass them. Running the plasma cutter on reduced generator speed can damage the machine.
Who Should Buy a Forney Plasma Cutter?
Forney plasma cutters serve a wide range of users. The key is matching the right model to your specific needs.
The Easy Weld 20 P is perfect for DIY enthusiasts, hobbyists, and light maintenance work. If you cut sheet metal, thin brackets, or body panels occasionally, this machine has enough power. Its low weight and 120V operation make it ideal for home garages.
The 40 P suits serious hobbyists, small shop owners, and farm and ranch operators. If you regularly cut material up to 1/2 inch thick, this model provides the power and duty cycle you need. Dual voltage gives you the flexibility to work in different locations.
The 45 P PRO targets professional fabricators, welding shops, and industrial users. If you cut thick steel daily and need production level speed, this is your machine. The Forney Ignite Torch and long reach capabilities set it apart from the other two models.
