In contrast with the traditional welders that most of us are used to, an inverter welding machine is a comparatively new and creative form of welder that has a variety of benefits. Compared to heavy copper or aluminum transformers and rectifiers used in conventional welders, inverter solderers use advanced silicon-based technology. There is no doubt that they produced quite a few teething problems when inverter welding machines were first launched, as any modern invention would do. However, since then, inverter technology has proven to be very efficient, cost-effective and in fact, has a whole bunch of advantages. Let us take a closer look at how an inverter welding machine works and why you may benefit from using one!
An inverter welding machine is in plain terms, an electrical voltage control device. It transforms the AC power supply into a lower functional output voltage in the case of an inverter welding machine - for example, from 240V AC to 20V DC output. Unlike traditional transformer-based devices that rely predominantly on a single large transformer to manipulate voltage, inverter-based devices use a set of electronic components to convert electricity. An inverter welder operates by raising the primary power supply frequency from 50Hz up to 20,000-100,000Hz. This is accomplished by using electrical controls that incredibly rapidly turn the power on and off. The transformer size can be decreased very drastically by regulating the power supply in this manner until it reaches the transformer.
The biggest advantage of an inverter welding machine is that it has a relatively thin, portable footprint, and can be brought around like a lightweight briefcase. Inverters are sleeker, lighter, lighter, and flexible in weight, utilizing even smaller transformers. This is remarkably similar to a conventional welder that is notoriously voluminous and does not work in narrow spaces. They use less electricity in comparison and can run on standard household power. Lower power consumption means that the inverter welding machine can be installed into any normal 110-volt wall socket with the household current instead of a high voltage current. This is remarkably similar to a conventional welder that is notoriously voluminous and does not work in narrow spaces.
Quality inverter welding machines would have a performance level of about 80-90 percent, whereas traditional welders have a slightly lower efficiency of around 50 percent. This is due to the fact that in traditional devices, the bigger transformers have higher resistance and therefore losing a large amount of energy by heat dissipation.
Higher Duty Cycles
Inverter welding machines, again due to the difference in transformer power, usually achieve considerably higher duty intervals. In an inverter unit, while the smaller parts heat up easily, they can be cooled much more effectively and quickly. In standard "transformer" welders, however, the parts are much larger and hence tend to store heat and take longer to cool.
Flexibility with AC or DC Output
Most typical so-called transformer manual metal arc welders have only AC output, meaning that the types of electrodes with which they can weld are limited. However, with an inverter welding machine, the current is much more readily rectified into DC, which means they can weld a wide range of different welding electrodes. It also suggests that such manual metal arc inverters are also suitable for DC TIG welding, which is not possible with conventional AC machines.
Power Usage more viable
Being so popular means that the use of generator power is much more practical with inverter welding machines, which can be run on smaller portable generator packs - something that is still not possible with traditional transformer machines. It should be recalled that there are risks involved with the use of generator power - for more information, read our report on the use of generators with inverter welding machines.
With all this being said, the inverter welding machine, of course, is not the ultimate and is the ideal system for all kinds of welding requirements. Components of high-tech electronics are responsible for the explanation that an inverter welding machine will run on a lower voltage current. The argument is correct that inverter welding machines are comparatively weak and thus vulnerable to more frequent breakdowns, and thus their use would lead to higher costs per amp.
