It's not hard to learn how to do it. Once you've taken the basics of mig welding you will never forget it. First when you decide how to mig weld, is if you are going to use gas-less flux cored wire or solid wire with gas shielding. If you are welding at home, more than likely your best bet would be to use less gas mig welding wire. If you choose to use solid mig welding wire you will have the additional cost of gas that comes in bottles and bottle rental fee itself. In Australia this is what we should do. If you're lucky and you live in the United States for example, I believe that you really can buy your gas bottle right out so you do not have to keep paying the monthly rental fee.
If you must use your mig welding wire tip contacts the right size for the right size. So for example if the welding wire 0.9mm in diameter you will need to use the contact tip is marked 0.9mm. Exceptions to this rule is if you are using flux cored wire or aluminum wire. In this case you need to use the contact tip which is the next larger size, which in this case would be the end of the size of 1.0mm contact. Also you must ensure that the drive coil or coils for wire feed marked the same size. There are three types of flow are available for the feed rolls. Profiles available are "vee groove", "u groove" and "knurled groove". Each designed for specific types of wire. Use the vee groove for solid wire, au groove to groove aluminum and knurled for flux cored wire. If you are using the wrong roller you will have trouble feeding the wire that will give a bad weld. Next you need to install wire welded to the engine. And the trick with the tensioning mechanism is to ensure that you do not tighten it too much. If done too tight, the wire will squash out of shape. Copper wire will begin to peel-less solid and gas and aluminum wire would be difficult to feed through the welding torch.Now make sure you wear appropriate safety equipment such as boots, overalls, gloves and welding helmets.
Attach the ground clamp you for your work and adjust wire feed speed and voltage regulation in accordance with manufacturer guidelines. Many mig welding machine today will have a chart on the display parameters for the welding wire feed speed, etc. If you do not have this machine because it was too long for example, began to make several exercises weld some scrap metal. Once you have a good setting then you can transfer to the job you want to work on. After completion of welding you may need to dress up all the welds with angle grinder depends on how well you are. I want to use the disc cover as metal surface nice and smooth blend.
