Welding with the use of gas dates back to the middle of 1800's, where the mixture of oxygen and hydrogen were used in the making of jewelery. Today, we use a different mixture of oxygen and acetylene which together can produce a flame temperature in excess of 6000 ℉. This type of Welding Equipment is not only used for welding, but also to heat materials for bending and straightening, brazing and cutting.

An oxy-acetylene outfit is usually portable, versatile, and less expensive than an electric welding set up, and by using the correct tips, rods and fluxes, almost any metal can be welded, heated or cut. This equipment is ideally suited to the welding of thin sheets, tubes and pipes, but not economical for thick section welds.

Arc welding or stick welding calls for a higher talent degree and mastery of certain strategies. it is nice for welding on thicker, rougher metals the use of a flux coated stick electrode fusing the work portions together.

To avoid porosity and gain the best weld tour speed, it is important to dispose of immoderate scale, rust, moisture, paint, oil and grease from the floor of joints. an expansion of electrodes are available for the exclusive forms of steel this is to be welded.

The electrodes need to get replaced as the warmth builds up and the stick melts down, inflicting a molten weld puddle at the work piece fusing the work portions together. the weld need to be cleaned while finished due to the flux electrode forming a slag blanket over the weld bead. the use of an arc welder is a relatively sluggish technique and is right for the greater skilled person.

MIG welding is normally lots less difficult than gas or arc welding. a spool of weld cord is constantly driven with the aid of a feeding system through the mig gun because the trigger is pulled, so in contrast to arc welding, there may be no need to constantly update electrodes.

A small amount of practice is required to set up the wire feed speed and also the power. The wire speed needs to be adjusted to suit each power setting, and with a little practice, the correct settings are easily achieved.

MIG process requires the use of a shielding gas which reduces spatter and produces very clean welds with no slag blanket. Flux cored MIG welding, on the other hand, uses a weld wire with a center core of flux which eliminates the need for gas shielding and offers easier, portable welding outdoors and on dirtier metals. Both processes of welding are very fast and allows you to weld the thinnest and thickest of metals.

Generally, the first thing to decide when buying a MIG Welding Equipment is what you are going to weld, and how often. If you are planning to weld thicker metals, then a welding equipment with higher amps is required, but for thinner metals like car bodywork, any welding equipment with a minimum setting of more than 30 amps would be unusable. Welding for long periods can cause the unit to overheat, so a welder with a fan would be a big consideration for heavier or industrial use.
