What is the difference between arc welder and inverter arc welder?

Answer 1

Both use electrical current to melt the base metal and the filler metal. Both could be considered ARC welding. Most welding is done with an electrode (stick) and as the electrode becomes consumed the weldor has to stop and replace it with a new one. MIG welding uses a spool of wire and can be run for hours on end. MIG is usually easier to learn.

Answer 2

a mig welder has wire fed through your lead a tig welder is kinda like soldering you have your torch and wire feeding together
Most MIG welding applications are relatively easy to do. MIG, correct nomenclature is Gas Metal Arc Welding GMAW, utilizes a spool of welding wire that feeds thru a gun held by the operater. Once the machine is set the operater only has to pull the trigger and move the gun to produce a weld bead. TIG, correct nomenclature is Gas Tungsten Arc Welding GTAW, utilizes a hand held torch to heat and melt the metal while the operater feeds filler metal into the weld with the other hand. This filler called rods or wire is usually 36" long and anywhere from 1/16 to 1/4" in diameter and are usually matched to the metal being welded. Pay wise most TIG weldors make more than MIG weldors.

Answer 3

A regular welder uses simple electronics and is mostly mechanical controlled; it also has a huge transformer. Inverters are mostly processor controlled; they have small Transformers and are more efficient because they utilize high frequency switching.

Answer 4

MIG (metal inert gas) welding and MAG (metal active gas) welding are two sub

types of welding method classified as GMAS (gas metal arc welding). In both

there processes a continuous metal wire surrounded by a shielding gas are

fed through a welding gun. Of the two processes the first one to be

developed was MIG process. This process was costly because of high cost of

inert gas and therefor was not used that widely. It was mostly used for

welding of non-ferrous metals. Subsequently the MIG process was developed

which used semi active gas such as carbon dioxide (CO2). This allowed the

process to be used for much wider applications.
