Ramsond Group is an American company, headquartered in Detroit, Michigan. In the last few years, Ramsond has quickly become a recognized, reliable and reputable source for a variety of industrial and consumer based products. Ramsond’s expanding product portfolio now includes both industrial and consumer based power generation (thermal, combustion and alternative power generation), appliances (refrigeration and air conditioning), water treatment and industrial and construction tools and machinery. Ramsond’s rapid growth of its product portfolio and its continued success are undoubtedly the result of its uncompromising focus on quality and after-sale service.
The Power Technologies Division of Ramsond Group has introduced its newly redesigned Ramsond CUT 40D, a 40 Amp, Dual Voltage, Inverter Technology, High Frequency, Plasma Cutter. Ramsond CUT 40D is the redesigned version of the original Ramsond CUT 40. While maintaining the same original appearance, the 40D is now a dual voltage plasma cutter (110V and 220V). It has been internally redesigned to incorporate the latest high frequency inverter technology using V-MOSFETs along with PWM (Pulse Width Modulation) which help deliver a far more constant, concentrated and precise current to the cutting surface. Furthermore, as a result of these improvements, CUT 40D has been substantially reduced in size and weight. With the Ramsond CUT 40D, regardless of your training, you can achieve smooth, clean and uniform cuts of wide range of surfaces and material (e.g. stainless steel, carbon steel, alloy steel, copper, brass, aluminum plate and other conductive material) with minimal heat input and without distortion of metal. This model has been designed so it is easy to use by the do-it-yourself user, while fully accommodating the demands of professional operators.
The CUT 40D Inverter plasma Cutter rectifies the mains voltage (110V or 220V) into DC (Direct Current), which is then fed into either a series of MOSFETs (Metal – Oxide – Semiconductor Field Effect Transistor). These MOSFETs (transistors) are switched at thousands of Hertz, which greatly reduces the magnetic flux, and therefore the size of the transformer. Hence, the use of MOSFETs allows for a compact and light weight machine such as 40D to operate at it performance parameters.
TRADEMARK ISSUES & QUALITY COMPONENTS
Although Ramsond can protect the use of its legally Registered Trademarked name, it cannot trademark the word “CUT†or the number “40†or the letter “D.†Therefore, other suppliers have similar appearing plasma cutters under the name “CUT†and/or “40D.†But, it is crucial to note that they are not produced by Ramsond. There are critical differences in plasma cutters that should be considered. Most importantly, the critical components used in a plasma cutter determine the performance and durability of the machine. By way of example, MOSFETs, the heart of a plasma cutter/welder, are the most critical (and most expensive) component of a plasma cutter. They are the mechanism by which the necessary cutting power is produced.
A recent industry investigation of Chinese manufactured welding/plasma cutting equipment has revealed a disturbing pattern of using SECOND-HAND, RECYCLED MOSFETs. All components used in Ramsond equipment are BRAND NEW. Ramsond products, including Ramsond CUT series plasma cutters, use only the best and the most premium components. All critical components used in Ramsond equipment are selected by its team of US specialists to ensure the highest quality and durability. For example, MOSFETs used in Ramsond CUT series plasma cutters are manufactured by FUJI and TOSHIBA (TOSHIBA for CUT 40D and FUJI for CUT 50D series).
Cut at 12 Times the Speed of Sound
Plasma cutting is a process that is used to cut steel and other metals using a plasma torch. In this process, an inert gas (compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface that is being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut. The plasma, which is maintained between the work-piece and electrode, travels at over 9000 MILES PER HOUR (15,000 km/h). That’s over twelve times the speed of sound.
Advantage Plasma vs. Oxy-Fuel Torch
Plasma does not use expensive, hazardous gases, only compressed air. It imparts much less heat into the piece being cut, eliminating warping. It leaves little to no slag to clean up or grind off. The cost per cutting hour can be less than oxy-fuel since there is no gas cost. It is also much quicker and easier. So, you cut better, faster and inexpensively.
There is not a lot of skill or training required to operate a Plasma cutter. The torch should remain at a 90-degree angle. With the Ramsond CUT 40D you can keep a standoff or drag the tip of the torch on the metal.
RAMSOND CUT 40D is user friendly. It has only two control; the On/Off switch and the Amperage Control Knob. You can change the amperage when you want to cut thicker/thinner material. However, many operators will leave the amperage switch on full output for all thickness of metal.
Air Requirements (Included Air Filter/Regulator)
Compressed air is the most popular gas used for plasma cutting. You can use an air compressor or a bottle of compressed air. The CFM (Cubic Foot per Minute) is important because that is the amount of air that will be distributed per minute and will keep your RAMSOND CUT 40D running consistently. The PSI (Pounds per Square Inch) is the actual air pressure required to operate your CUT 40D (50-75 psi). The other gas used is nitrogen, but the only advantages to using it is for when cutting stainless steel. You will get a cleaner cut but the cut thickness will be diminished a little. With some exotic metals a gas mixture may be needed.
You will also want to have clean and dry air when operating any plasma cutter. Ramsond CUT 40D comes already equipped with an air filter/regulator that is designed to keep the air dry and clean. Dry air is important because if there is moisture in the line it will travel with the air and exit the end of the torch. This is not necessarily dangerous but will shorten the life of your consumables because the arc will follow the moisture in all directions and erode the tip prematurely.
Manually cuts variety of material in thickness of up to 1/2 in. (12.7 mm) and severs 3/4 in.
High frequency inverter technology using Advanced Semiconductor Circuitry, premium components (TOSHIBA MOSFETs), combined with Pulse Width Modulation (PWM) result in faster, more precise cutting.
Current strike protection with integrated slow start setting, over current protection, overheat protection and stable HF touch arc ignition lead to safer, faster, narrower, smoother, cleaner and more uniform cut and leads to Higher Efficiency.
Easy to use with only an ON/OFF switch and Amperage control.
Easily adjust the current (from 20-40A) to suit the cutting surface
Easy to carry (19 lbs) and compact to store
Torch, consumables, Ground Clamp, Air Regulator/Filter and more.
