Lincoln Electric 20 is the smallest and lightest of all Lincoln plasma cutters but with adequate electrical and mechanical capabilities to cater to the needs of HVAC projects, auto body workshops, contractual works, sheet metal fabrication, and households.

Not essentially cheap, this one comes at a more affordable price than other Lincoln models. The package includes a hand-held torch, 9.5 ft. cable, ground clamp, 8 ft. cable, power plug, and cord, and instruction manual.

Pros

  • Inverter design that contributes to a lightweight unit
  • Top mounted regulator for ensuring a consistent flow of air pressure
  • Energy-efficient fan for cooling the unit to help maintain the maximum duty cycle
  • Low air pressure requirements
  • Carry handle for easy portability and saddle hooks for cable storage

Cons

  • Barely capable of cutting expanded metal with precision

Attention!

  • It’s not compatible with a CNC table or machine.
  • You’ll have to buy consumables separately. Choose only the recommended set.

Desirable Feature/Quality

  • Higher cut thickness and amperage output
  • Thermostat overload protection

2. Lincoln Tomahawk 375 Review

Product Features
3 Reviews
Product Features
  • Series: Tomahawk 375 air
  • Rated output: 10 to 25A
  • Weight: 50 pounds

As an Amazon Associate I earn from qualifying purchases

As much as Tomahawk 375 has been crafted to be a performance-driven machine, it’s a feature-rich plasma system that serves diverse needs like onsite maintenance, simple construction works, HVAC (air ducting installation), and demolition. It’s also an ideal unit for rental.

Its ability to cut through metals like aluminum, brass, copper, and steel (mild/stainless) lets metalworking hobbyists and DIY people to look beyond basic plasma cutting. The machine doesn’t allow for gouging metals, though.

The package includes LC25 torch, 10 ft. cable, built-in air compressor with standard connection for an external unit, air regulator, air pressure gauge, water separator, work cable, clamp, consumables, input power cord, shoulder strap, and instruction manual.

Pros

  • A portable unit with an internal air compressor
  • Reasonable cutting abilities with external compressor connection system for greater precision
  • Continuous Output Control for allowing the arc to stay consistent for different thicknesses
  • Touch Start for safe arc initiation
  • Rapid Arc Restrike for fast and versatile cutting experiences
  • Preflow and Postflow functions for great efficiency plus material throughput
  • Purge Control system for allowing a control over the airflow requiring no arc initiation
  • Over-current along with thermostatic protection for efficient operation
  • Parts-in-Place mechanism for facilitating the correct installation of components
  • LED indicators for accurate data for power, thermal system, and output
  • Built-in water separator for clean and dry air supply

Cons

  • Slow cutting rate (travel speed) for stainless steel
  • Poor results from cutting aluminum

Attention!

Consider replacing the electrodes as they erode 0.025 inches. Do the same if you see erratic and/or green arc. Make sure you get a full set of consumables (both nozzle and electrode) at the same time.

Desirable Feature/Quality

  • Gouging ability

3. Lincoln Tomahawk 625

Product Features
2 Reviews
Product Features
  • Lincoln Electric Tomahawk 625 Plasma Cutter (LEW-K2807-1)

As an Amazon Associate I earn from qualifying purchases

Tomahawk 675 is clearly an upgrade to the 375 model, not essentially for a higher price but for enhanced cutting abilities and an added convenience, such as gouging metals.

It’s designed for almost the same purposes in terms of applications and metal supports as those of Tomahawk 375. The good news is that its performance is even more efficient on some occasions, if not always, thanks to the improved torch design.

However, you need to think about purchasing an external air compressor because this model doesn’t include one, and that’s what adds to its few limitations.

The package includes an LC40 hand torch, 20 ft. cable, air regulator, air pressure gauge, water separator, work cable, clamp, consumables (electrode, nozzle, and swirl ring), input power cord, shoulder strap, and instruction booklet.

Pros

  • This plasma system offers all the standard benefits of the 375 model. Where it excels is the drag cutting function that gets to be improved.
  • Another plus is the duty cycle which can be enhanced with a little effort to keep the surroundings conducive to metalworking. It means you’ll pass more of action time and less of idle time.

Cons

  • Difficulty achieving clean and precision cuts through aluminum (skills required)

Attention!

To pursue standard cutting, you have to ensure that the current levels are high and the metal plate is thicker than the usual. All parts required for this type of cuts come included.

For contact or drag cutting, make sure that the amperage settings aren’t high and the plate is thin. Although the package includes most of the consumables required for the job, you still need to buy a special nozzle that is available from the manufacturer.

Since gouging is one of its specialties, you’ll want to try it. Well, buy a special nozzle and a shield cup which are particularly designed for gouging. Get the one from Lincoln.

Desirable Feature/Quality

  • A built-in air compressor
