Control System The control system of a stick welding machine allows the welder to adjust various parameters such as amperage, voltage, and polarity. These settings determine the heat input, penetration, and overall quality of the weld. Welders must understand how to calibrate and fine-tune these controls to achieve optimal welding performance. Output System The output system of the stick welding machine manages the transfer of current to the electrode and workpiece. It consists of cables, clamps, and connectors. The electrode holder, also known as the stinger, is connected to the positive terminal of the machine, while the work clamp connects to the negative terminal. The output system ensures a reliable and efficient transfer of electricity from the machine to the welding area. https://www.kende.com.cn/product/manual-metal-arc-mma-or-stick-welding-machines/mini-igbt-inverter-welding-machine-mma-metal-case-with-plastic-frame-portable-easy-to-start-arc-anti-sitcker-arc-force-vrd-dc-single-phase-220v230v-120a-140a-160a-180a-200a.html
