What is an Inverter Welding Machine?
Although many of the basics of welding haven’t changed since World War II (and some of them remain unchanged since flux welding was introduced in the latter part of the 19th century), considerable advances have taken place in the equipment used for the process.
Indeed, many of the modern would seem almost magically compact, powerful, and versatile to early welders, were they somehow to cross time to observe what happened to their craft in the future.
These technical changes have made
This is a huge boon to independent welders and hobbyists, much as the Internet has allowed many types of freelancers to use their skills and creativity to earn money without being fully dependent on the faltering corporate structure of the United States. are now portable enough to be carried into practically any nook or cranny that a human can climb or crawl into. Part of this technical advance consists in the availability of many different kinds of , too.
Inverter take the alternating current (AC) that comes out of the socket and convert it into direct current (DC), then use small built-in transformer to produce the desired amperage and wattage. These machines are a good choice because they automatically analyze, and correct for, any discrepancies between the power supplied and the power needed for the settings you have chosen.
Inverters also allow very fine tuning of the arc with their infinitely adjustable “variable frequency”. Their one downside is their price, since they are naturally quite a bit more expensive than their less advanced counterparts. AC and DC power can be produced by an inverter, and they come in CC, CV, and CC/CV configurations. A CC/CV inverter is probably one of the most flexible machines on the current market.
Transformerrepresent an older type of technology and are consequently bulkier, heavier, and far less versatile. They are good for AC MIG welding and not much more. Their major advantage, as might be expected, is that they are very cheap, comparatively speaking. They only come in CC (constant current) configuration. Their main function is to allow adjustment of the voltage.
Transformer rectifier machines are the larger and more versatile transformer machines that were devised pre-inverter to provide all other types of welding current. Their bulk and aging technology makes them a liability to the modern small welder, however.
