Lotos LTP5000D 50A Air Inverter Pilot Arc Plasma Cutter Review

The Lotos LTP5000D 50A is a recent entry to the market, and it is taking the plasma cutter market by storm. This is one of the only plasma cutters (and at the time of this writing is definitely the most inexpensive plasma cutter) on the market to make use of insulated-gate bipolar transistor (IGBT) technology instead of the traditional MOSFET transistor. The IGBT technology is fairly new and was first invented in the 1980s. Through refinements in technology, this transistor is now able to rapidly generate the large power pulses needed to power an excellent yet compact plasma cutter. In this Lotos LTP5000D review, we will be covering not only the Lotos LTP5000D but also giving you a comparison to its similar model, the LT5000D.

In comparison, the Lotos LT5000D (notice the lack of “P” in the abbreviation) is still running on MOSFET technology. The Lotos LTP5000D is the first mass-produced, highly-reviewed plasma cutter to use IGBT technology that exceeds the capabilities of MOSFET while keeping the price low enough for a hobbyist to add to their shop. The manufacturer states that the IGPT both increases the reliability and power of the plasma cutter without a significant increase in cost or price, as the LTP5000D weighs just a pound more and is a similar cost to the LT5000D. As a result, the manufacturer states that they for commercial prospects, the company now almost exclusively sells the LTP5000D over the LT5000D.

Where the Lotos LTP5000D 50A really shines is when it comes to cutting rust. The Lotos LTP5000D is what is known as a pilot arc plasma cutter, which means it can generate its own arc without contact. Most plasma cutters cannot generate an arc (and therefore cut) unless they are in direct content with plasma cutters (this is known as a “contact plasma cutter”). This is important because a contact plasma cutter will not fire when it is in contact with rust, meaning you have to blast the rust off before you can cut, which is very inconvenient and a big hassle. The Lotos LTP5000D’s new technology gets around this, as this cutter can cut through rusted metal without any de-rusting required.

  • Operates as both a pilot and contact cutter
  • No need to clean rust off of metal before cutting
  • Handles up to 3/4″ cuts

The Reviews

Given that this is a new plasma cutter, one actual customer review has been collected. However, this review was glowing and the customer was very happy with their purchase. They reported that they bought it to work on an older, rusted car, and it did its job so well that they have used it for all sorts of tasks. The particular reviewer says it is much smaller than he expected (it only weighs 27 pounds) yet performs at a much higher level than his friend’s Hobart. He also reported that LTP5000D was able to cut through 1/4″ metal very easily, and handled 16 gauge sheet metal and 7/16 bolts with extreme ease.
