Welding is the process of fusing two metals together by melting its point of contact. This process is carried out by welding machines. There are many different types of welding machines that work off of different power sources. The motor-generator type is portable and can be used in places where there is no electricity. It runs either on gasoline or diesel. The AC transformer machine is lightweight and compact and can be used for light industrial use.
The electrode negative type is used for welding carbon and stainless steel. But no matter which type you have and no matter where you use it, you must be able to use it properly and safely, without causing bodily harm to you or harm to anyone else or anything else.
When using such a machine you must always remember to connect the ground cable to the materials you are working with or to a part of your workbench. The reason for doing this is that the heat generated by the machine is not in excess because the excess heat can damage the machine and its cables. You must read the instruction manual well before you use it so that you can follow the manufacturer’s guidelines well and not cause any damage. After you use the machine you must thoroughly clean it out with a steel brush or a power tool. Remember to wear safety gear like appropriate clothes or protective aprons, gloves, protective glasses and you should work in an area that is ventilated well.
