The recommends beginning, and expert welders alike keep the following 4 things in mind:
Safety is a must! Welding has enough energy to fuse two metals together; when used incorrectly, it can cause serious injuries.
Before you even think of welding, you must have the right gear. This includes a fire-resistant jacket, safety glasses, welding gloves, and a welding helmet. Also, make sure you have a well-ventilated space in which to practice welding and be sure flammable materials are kept far away from your workstation.
Training and practice are necessary. Different materials need to be welded differently, and it is important to learn the different welding processes and best practices of welding. There are classes online, trade schools, and even YouTube videos for learning how to weld.
Consider input voltage. Low voltage is enough for mild steel welding, but thicker materials will require higher voltage. Look for a machine that offers dual voltage as you learn and practice. This will allow you to move confidently from method to method without having to invest in additional welding machines.
Knowledge of consumables and materials is important. "Consumables" refers to the wire, electrode, or filler material used in welding.
It is also very important to learn about the materials you want to weld in order to make sure you use the right welding method for the materials you wish to use. Some processes require additional tools, while others do not. And keep in mind that you can always contact the manufacturer of your materials for more information when necessary.
