Ramsond introduces the 4th generation of its CT520DY. CT520DY is a 3-in-1 multifunction cutting and welding machine. It is a 50 Amp plasma cutter, a 200 Amp DC (Direct Current) TIG welder and a 200 Amp ARC/MMA stick welder. It is dual voltage 110V/220V and dual frequency 50/60 Hz. It is equipped with DIGITAL AMP DISPLAY, INTEGRATED PRESSURE GAUGE, FOOT PEDAL FUNCTION and FOLDABLE INSULATED HANDLE. It uses the most reliable high frequency V-MOSFETs by TOSHIBA along with PWM (Pulse Width Modulation Processor) which help deliver a constant, concentrated and precise current to the cutting/welding surface. Regardless of your training, you can achieve smooth, clean and uniform cuts (1 inch) and weld a wide range of surfaces and material (e.g. stainless steel, carbon steel, alloy steel, copper, brass and other conductive material) with minimal heat input and without distortion of metal. CT520DY is easy to use by the do-it-yourself user, while fully accommodating of the demands of professional operators. It has five controls; the ON/OFF switch, Amperage Control Knob, the Post Flow Knob, Function Selector and the foot pedal ON/OFF switch. It has an integrated air pressure gauge in the front panel of the unit, as well as a large digital display that conveniently displays the current (Amps) setting of the unit. Note: This is a DC (Direct Current) TIG Machine. For aluminum welding AC (Alternating Current) is recommended. Each Ramsond CT520DY comes fully equipped with all accessories: TIG Torch, Plasma Torch, ARC/MMA Electrode Clamp, Air Regulator/Filter, Argon Flow Meter, Set of Consumables for the plasma and TIG torches, and Ground Clamp. Plug is not included. It comes with a 1 year Limited Warranty (Parts and Labor). The consumables are readily available both through Ramsond and third party sellers and are reasonably priced.

This auction is for a brand new 3-in-1 multi-functional welder. This welder is made with advanced inverter technology, and they have three functions: TIG/MMA/CUT. The inverter power is the power that first changes 50/60HZ working frequency to high frequency (as high as 100KHz) with high power factor V-MOS, and then reduces the voltage and rectifies, and then output with PWM the welding and cutting power of high power factor. By using the inverter technology of switch power, the weight and volume of the mains transformer greatly reduces, while the efficiency is raised by over 30%. When working as MMA or TIG, the outer characteristic is constant current and the welding current doesn't change with the length of the arc, the current is very stable. When working as CUT, the arc is compressed by the rapid-circulating air, and then its temperature reaches 10000-15000"C in the state of ionization, thus turning into strong plasma arc. The plasma arc into cutting makes the energy more concentrating, and gets smooth arc surface, which may take convenience for later work. This industrial grade welder can be widely used in welding and cutting carbon steel, stainless steel, alloy steel, copper and other nonferrous metals. It's portable, efficient, energy-saving and stable, and the exchange cycle of the assembled machinery can be as high as 85%.

As one of the largest manufacturers of plasma cutting, tig/stick, arc welding equipment in the world, Lotos Technology is proud to offer an extensive selection of industrial plasma cutting and tig/stick welding machine with the CT520D. Lotos CT520D is a THREE-IN-ONE Digital Inverter Plasma Cutter (50A) / Tig Welder (200A) / Stick (MMA) welder (180A). You would have to purchase 3 separate machines to do what this ONE machine can do! Using this portable plasma cutter is cheaper than Oxyacetylene after just a few cuts. Less cleaning, less maintenance, less noxious gases, less hazards, simply less overall work and a better, cleaner cut. The torch trigger can be moved for a custom fit. It can be used in finger or thumb positions. The torch head is adjustable for tight spaces. High Frequency DC Plasma cuts thicker materials than standard DC plasma cutters. High Frequency Plasma cut faster with less distortion in the work piece. The Tig welder from this CT520D is clean and strong. This Tig welder is easier to use than any other Tig welder on the planet! An ARC (Stick) welder is a necessity in any industrial shop or home workshop. There are welding jobs that simply require ARC or SMAW (Shielded Metal Arc Welding). With arc welding, no shielding gas is required. Stick welding is cheap and effective: fill the large gaps and holes, weld the cast iron and weld the extra thick steel with the stick. For this Lotos 2011 latest model, we add the aluminum stick welding feature. It is patent pending.
