MIG Welding Equipments and Related Information


Visitors: 273

There can be no doubt that MIG (Metal Inert Gas) welding is a great leap forward in the advancements of welding technology. The almost perfected, all-in-one process makes MIG welding lot more convenient. Load the filler wire onto the machine, set your amperage, and there you go.

Learning the basics of the MIG welding equipment may call for some initial strain. But once you become familiar, MIG welding is an easy process and you will be able to obtain clean and tidy welds. In MIG, a spool of solid-steel wire is fed from the machine, through a liner, then out of a contact tip in the MIG gun. The contact tip is either hot or electrically charged, when the trigger is pulled and melts the wire for the weld puddle.

There is no denying that MIG welding is costly when compared with the other processes. MIG welding machines as also the filler wire are much more expensive than stick welding machines and electrodes. Besides, MIG welding applications are also restricted, as MIG welding may not be suitable for all types of welding.

There are automatic and semiautomatic MIG welding machines. An example of automatic MIG is a robotic arm often seen welding car frames in an auto assembly plant. Semiautomatic MIG welder is when an operator holds the MIG gun and manipulates the weld pool. In automatic MIG, an operator sets up and watches over the machine. An experienced welder is the preferred because he has the right touch and knows what it means to be in the welding zone.

But most MIG welding machines are semi-automatic arc welding machines in which a perpetual, breakable conductor electrode and a defending gas are supplied by implementation of a welding gun. On the tip of the gun, there is electrical energy to the wire. The shielding gas and the wire are set in movement simultaneously to create the weld when the mechanic lowers the induction of the gun.

A variety of MIG machine models are available in the market. The main difference between a cheap and expensive MIG welding machine is ease of use. Do not buy a MIG welding machine just because it's cheap! Ask some professionals before you buy and tell them the specifications if you can.

You can get a good quality MIG welding machine provided you can afford it. A good machine costs at least $400 to $500. You can buy a cheaper machine, but most of them may not be of reliable quality. But a redeeming feature about a small compact machine is - you can plug it right into 110-V outlets in your garage and commence operation.

But, please ensure there is a 50-amp fuse—or whatever the manufacturer tells you—or else, you will blow out your electricity. MIG regulates to several degree of electrode length and permits for long welds with lesser disruptions and intervals.
MIG welding machine is indeed versatile and apt for a variety of applications including - automobile body repairs and improvement, trailer hitches, unit projects, farm/ranch equipment repairing machine barrows, bicycles, and others.
The quality of MIG welders and the prices continue to fall as more of them are manufactured in Eastern Europe and China. Expensive MIGs are more reliable to use than low end welding machines because they have more efficient electronics inside and better wire feed units.

Inverters are starting to find their way into MIG welding machine market. They can offer a lot of features at a lower cost than the traditional transformer based welding machines. The inverter technology is currently aimed at increasing the speed of welding in high amp spray transfer, and avoiding the transitional globular transfer phase. Inverter based welders however do not currently offer any advantages for automobile body work.
