Arc welding is a constant current process, but the arc length has an effect on voltage. Reducing the arc length will decrease the voltage, and this reduces the heat in the weld. Increasing arc length will increase the voltage.
Assalamualaikum bhai. Arc ka system abhi new Arc welding machine me Digital aa rha hai. To aise me 5mm metal ke liye hot start, Arc force, current kitna rakhna chahiye. Please reply 🙏
