Great performance, cuts as described.Here's something about the Lotos lineup of plasma cutters that may be of importance to you but is never mentioned anywhere: The high-frequency start is just that, non-continuous. It will not make interrupted cuts. If you want to cut, for example, expanded metal, as the arc leaves the work edge the arc turns itself off and a 10 second cool-down cycle with air only starts. The arc will not restart until the 10 second cooling air period is complete. You must release the trigger for the cycle to complete (similar to a semi-auto firearm). You may not think that's any real big deal, but sooner or later you'll have a job where you need to quickly go from piece to piece and a continuous high-frequency unit will do that, but not the Lotos lineup.Some reviewers have problems with poor cut quality from the first cut and are very upset at Lotos. I'll describe my own first cut, perhaps it may help someone else.A visual inspection of the nozzle and the appearance of the electrode showed evidence that the unit had been used. Others have said that the manufacturer tests each unit before packing it for shipment and I agree that it seems likely. I was suspicious of the nozzle because it looked like it had been "touched down" on the work surface, but I used it for the first cut anyway.First cut was a piece of 1/4" hot-rolled steel, amps at 40A with 1/8" standoff. The arc did not penetrate, just dug what I would call a "ditch" in the steel. Part of the arc was blowing out across the top of the steel. My years of plasma cutting experience immediately said, "bad nozzle".I replaced the electrode and nozzle with included spare parts. Second cut, same piece of steel, and the awesome 30,000-degree plasma stream was about the diameter of a pencil lead and went through the steel like a giant razor blade.An air supply that is clean and very dry is critical to the operation of any plasma cutter. A single small drop of moisture in the air supply will cost you a nozzle and electrode. I recommend the very best dryer you can afford. The desiccant-type driers work well. The best type, in my opinion, is the refrigeration-dryer, which cools the compressor discharge air to below the dew point and collects the liquid water for automatic disposal. Works sort of like a home dehumidifier.Without a good air dryer, plasma cutting is an exercise in frustration (and can get to be quite expensive, if you have a water problem).Ed B.
