What equipment do I need to weld?
When you're looking to get into welding, there's three main aspects you're going to want to look at. First is always safety: What type of gear you need, and what's the safest way to do it? The second is power source. This has to do with cost and what you're looking to weld. And the third thing is the process, whether it's GTAW, GMAW, SMAW, or any other process.
The easiest way to find the information for all the safety parameters that you might need is in this link in the description of this video. There you can find all the information for the process and the type of welding you're doing, to make sure that you stay safe.
When you're looking to buy a power source for welding, you're going to have to look at a few things. First of all is cost. What can you afford? The second is the amount of power you have available, whether it's 110, 220, single phase or 3 phase. When you're picking out a machine, the type of electricity you have and the money you have available will dictate the type of machine you can purchase.
Now, when you're looking at the process, each process needs different type of electricity outputs. And when you're looking at the machines, make sure you look at three things: the voltage it can carry; the amperage, which is the heat; and the duty cycle. Duty cycle might be the single most important part of buying a welding machine. That means how long the machine can sustain the heat that it says it can give you. If a machine can do 300 amps, that's great, but if it can only do it for 30 seconds, that's not good enough. But if a machine can only do 100 amps, but it can do it all day, that might be a more useful machine for you to have in your garage.
Now, when you go to the store, make sure you look at what type of machine you have, where you're going to plug it in, and what it is you're trying to weld. If you're just fixing things around the house, or you're just looking to get into the obvious side of welding, or you're just trying to learn, don't pick something that's overly expensive. Pick something that's versatile, perhaps an inverter. Inverters are very versatile and becoming more and more popular. They can do all types of welding and at a lower cost. They also tend to work on multiple power sources, whether it's 220 or 110 or even 3 phase. Check with your store. Read up on it. Do some research. And find what's best for you, but always think about what it is you're trying to weld. That's the best way to find the right machine for you.
Once you've decided on the type of machine you've purchased, you're going to want to look at the process. Some machines will only handle a certain process, so some AC machines will only do SMAW, and then you know that that's all you can do. Some machines will do GMAW and SMAW and GTAW. Then you have more variety, but the cost goes up.
Now, if you're looking to just learn how to weld, the easiest way to do this is generally a simple GMAW machine. These are low in cost, easy to set up, and can run off 110 power. They're available in most stores and almost all companies will have some low-cost offering for you to purchase. These are great ways to learn how to weld, and there's lots of great, interesting videos, including on our website, on how to use GMAW process.
If you decide to go with a GMAW or GTAW process, keep in mind that there is gases involved. Now, every area has their own legislations for gases, and sometimes there may be some contracts or some safety regulations that you must follow. Make sure you understand them, and always be safe when working with gas.
