Inverter Welder Reviews - How They Work, Benefits, And Models Available

Inverter Welders Are The Upgrade From The Standard Industrial Version- Portable, Lightweight, and Just As Powerful while using less power.

Inverter welders are an improved version of the traditional welder. Not only are they smaller than traditional units, they are lighter which allows for portability. This also allows for usage in tight spaces where a traditional welder would not fit. In addition, this type of welder requires less power to operate. By design it utilizes a standard plug and steps that power up internally.

These welders may also be run off of a regular generator rather than an industrial sized one. They are more tolerant of what is referred to as "dirty power" as well. Dirty power or low quality power, often can lead to poor welding jobs, improper operation and more time on a job. Inverted welders don't have this problem.

Benefits Of Inverter Welders and How They Work

A lot of experienced and professional welders are finding the inverter welder to be an asset to add to their arsenal of welder types. There are many reasons for this including their capability to internally step up power from a standard household current plug (120v) to 220v of power with only 120 volts of input.

The traditional welder uses, typically, a 220v power input plug rarely found in shops and households (and smaller generator plugs available allowing for portability of welding work), which often costs more to install and even uses more in electricity than the 120 plug would use.

It does this with internal circuitry and electronic components not found in other welder types so the cost is a bit more, but well worth it. Just the electricity you save alone for the same jobs can in time pay for the extra cost of the unit(s).

The standard plug application on inverter welders offer the same power with less power input and it's more convenient, adding flexibility in where and what type of work you can perform with it. Nobody wants to have to tug around an industrial sized generator just to do a weld job off-site. The inverter technology steps 120v up to 220v without requiring more power.

Let's talk about the various models and costs you can expect in finding a good inverter welder. On the left are several reviews for great inverter welders, on the right you'll find more choices as well.

The inverter welder is always a smart choice for any size job (larger versions for bigger jobs) as it offers greater flexibility for the user. Not only can it be used in small places and run off of standard household voltage, it also saves on electricity bills.

The only downside to this particular style of welder is increased cost over traditional welders as well as the fact that this welder has advanced controls which require more care than other styles. These are small downsides that can easily become upsides if your willing to learn the unit's many functions and versatility.

Another great thing about the inverter welder is it comes in a versatility of different types like Mig and Tig Welding models. Different models are more or less expensive allowing for more refinement where budgeting for the right welder is concerned.
