VCT VT10000-10,000 Watts Heavy Duty Continuous Use 110V / 220V / 240V Step Up/Step Down Voltage Transformer

great service and product

Needed a 10kW transformer to amplify the voltage for my 4.2kW plasma cutter from a 110V supply, and this thing looked like a perfect solution. It's advertised as "continuous" and "heavy duty" BUT after barely working a couple of months, for no longer than 2-3 hours a day, it at one point went happily down in a puff of smoke and loads of burnt wiring inside it. When I opened it up I discovered a mess: 1) There is NO fan inside it -- a fan is found in most cheap welding sets these days, one'd expect the Indians or the Chinese who assembled it to install one, but nope, no luck. So all the "cooling" is passive. 2) The insulation on wires around the core is plain THIN. Cheap stuff. Another measure to cut production costs down and reduce size. At the expense of performance and safety of course. 3) Everything appears crammed and even the few bits that didn't catch FIRE are oxidized. After contacting the Seller which when I bough the transformer went under the name of VCT ELECTRONICS, and asked for a refund or a replacement, I was told that it was my fault for burning the transformer, and wrongly quoted that "heating elements require 3x capacity". A 4.2kW plasma cutter has no heating elements inside it, and works by means of an electrical arc. So I was much and well under the 10kW range (had at least 5.8kW allowance, DUH...). They utterly refused to change or refund it. I would NOT RECOMMEND this transformer nor this Seller. Save yourself a few hundred bucks and buy something quality, with a fan and proper insulation, and from a REPUTABLE seller. Cheers.

Live in NZ wired up my garage for 110 power tools awesome

Arrived broken and the parts that were intact were cheaply made. Got charged a restocking fee even though the transformer was broken on arrival.

One star is too much. What I was send was a refurbished piece of junk, that was so banged up that leaked some oily liquid in the receipt and the whole box looked like dried wet cardboard. This thing was heavy as can be expected and looked like someone played football with it.
