Understanding Welder Amps
When it comes to welding, understanding amps is crucial. Amps, short for amperage, is a unit of measurement used to determine the amount of current flowing through a circuit. In welding, amps are directly related to the heat produced by the welder, which ultimately affects the quality and strength of the weld.
What are amps?
Amps, also known as electrical current, refer to the rate at which electric charge flows in a circuit. It is a measure of the number of electrons passing through a given point in one second. Amps are one of the three fundamental units of measurement in electricity, along with voltage and resistance.
When it comes to welding, amps are highly significant as they determine the heat input to the weld. The higher the amps, the more heat is produced, resulting in a hotter and deeper weld. However, using excessive amps can lead to weld defects like burn-through or distortion. On the other hand, insufficient amps may result in weak and incomplete welds.
How many amps do you need?
The required amps for a welder depend on various factors, including the type and thickness of the metal being welded, the welding process used, and the specific welding application.
