What determines the temperature of the manual metal welding arc?

The temperature of the manual metal welding arc is primarily determined by the welding current, the type of electrode used, and the arc length. Higher welding currents generate hotter arcs, while different electrode materials can influence heat distribution and efficiency. Additionally, maintaining an optimal arc length ensures consistent heat application, affecting the overall temperature during the welding process. Factors like shielding gas and environmental conditions can also play a role in temperature variations.
