Three units are used to describe any arc welding process. They are voltage (V), amperage (A), and wattage (W).
Voltage:
- Voltage is the measurement of electrical pressure.
- Voltage control the maximum gap the electron can jump to form an arc.
- Welding voltage is associated with welding temperature.
Amperage:
- It is the measurement of the total number of electrons flowing.
- Amperage control the size of the arc.
- The higher the amperage setting, the higher the heat produced by the welding arc, and the lower the amperage setting the lower the heat produced.
- Each diameter of the electrode has a recommended minimum and maximum amperage range and therefore a recommended heat range. Amperage is associated with the welding heat.
Wattage:
- It is the measurement of the amount of electrical energy or power in the arc i.e how much heat and temperature an arc produces.
