Hi, how can I help?

Volts, amps and plasma power

In plasma cut process, we are talking about watts-power. In arch weld, whether it is a stick, MIG, TIG or something else, we are talking about amperes-current. We are used to thinking about the relative nominal power in arch weld, based upon the current strength that the machine delivers by the means of arch.

Plasma cutting differs. In plasma torches, both voltages and amperes are counted. The cutting speed of the plasma cutting machine is dependent on watt numbers (volt and amperes) it produces.

Thus, a comparison of the current does not solve the matter. Our plasma cutting machines tend to produce greater than regular voltages, and that is why we are going to clarify this:

Like certain V8 engines possess greater power on truck-wheels compared to other ones; this is the case for certain plasma cutters.

Strength: The sizes of the truck engines show how they work likewise amperage shows the performance of plasma cutting machines. Though just looking only at the engines, we may miss the main aspects that provide significant performance improvements.
Voltage: The RPM on trucks is compared with the output voltage of plasma cutters. More RPM provide greater output powers. Greater output voltages ensure relatively fast and clean cutting.
Watt Power: Horsepower lets us know whether a truck has capability of managing a certain challenge; just like power in case of plasma cutting machines. So, these two indicate the power output of machines. Some just achieve a particular result. But some reach more than desirable powers.
Specifying output powers of a plasma cutting machine is easy: the current strength of the plasma system must be multiplied by the output voltages. In case no volt is seen in the list, contact the manufacturers. The reply (ampere x volt) equals to watts (or kilowatts). This comes to mean that two systems possessing the exact numbers of ammeters can have completely different level of powers.

For instance, the old model Powermax 30 and the new Powermax 30 XP possess 30 amp system; nevertheless, the Powermax 30 XP has greater power due to its more voltages. The Powermax 30 is of 83 output voltages, whereas the Powermax 30 XP is of 125 voltages. Multiplying both numbers by 30, you will have 2490 W or 2.49 kW for Powermax 30 and 3750 W or 3.75 kW for Powermax 30 XP. Despite the fact that two models are rated at 30 A, the Powermax 30 XP has got 50% more power.
