Welding is a process which involves specific steps and actions created to successfully melt metal. There are certain factors you to need consider to ensure that your welding is done correctly. Your main goal should always focus on producing a strong weld. You should ensure that any harmful contaminants will not be able to get in contact with the meta while it’s still in liquid form. This is because they may cause cracking or weaken the weld. Welding involves some inherent risks since it uses an electric current which generates approximately 1,600 of heat. The flash of light it produces can also cause a person to be blind. Today, we’ll discuss about DIY Welding Tips which will help you protect yourself while successfully creating a strong weld.
OPTIMIZING THE POWER SOURCE
First and most important of all before beginning the welding process, you have to make sure that you’re using the required power. You can check this by referring to the name plate listed on the machine itself. If you’re using a 120 volt machine, it should be paired with a 20 amp breaker. By powering up the machine you’ll be able to ensure that it’s working properly while using the required power. To avoid voltage drop problems, avoid using heavy gauge cords and extensions.
USING THE CORRECT ELECTRODE POLARITY
Depending on the type of process you’re doing, whether it’s Flux Cored Arc Welding (FCAW) or Gas Metal Arc Welding (GMAW), you should make use of the correct electrode polarity. MIG machines requires shield gas when using GMAW. Its electrode is copper in color. The most frequently used one is ER70S6. Make sure that the machine’s polarity is set to be electrode positive. On the other hand, a MIG machine which uses FCAW requires a flux core electrode. The most common one used is e71t wire which are silver in color and don’t make use of additional gas.
CHECKING THE THICKNESS OF THE MATERIAL
It’s always essential to check the process you’re using and its electrode size are appropriate for the material. GMAW is best used for welding material which is 16 gauge or thinner. Generally, 120 volt machines do not have the ability to produce accurate welds on steel materials which are thicker than 1/8 inches unless it’s using FCAW. When working with a 1/8 inch welding using a 120 volt machine, you should always use flux core in order to ensure that you’ll achieve a strong weld finish. The GMAW process is typically cooler than FCAW which makes it the perfect choice for welding thinner steel materials.
CHECKING THE GROUND CLAMP & HELMET COVER PLATES
The ground clamp, also referred to as the work lead, should always be clamped directly to a metal part of your work which is clean and bare. If you notice that your machine is not successfully producing an arc, it’s usually because of an inadequacy of electrical continuity. Your helmet’s cover place will rarely last for 10 hours of welding. At this time, it will become charred and smoky. When you can’t clearly see the material you’re welding, it causes accidents and injuries. To avoid this, always ensure that you’re frequently changing your helmet’s cover plates.
