How is the SMAW process typically initiated?

The SMAW process is typically initiated by striking an arc, which is akin to the action of striking a match. This involves bringing the electrode into contact with the workpiece briefly and then withdrawing it slightly to create a gap. This gap forms an electric arc that generates the necessary heat for melting the electrode and the base material, resulting in the fusion of metal. Striking the arc is a critical aspect of SMAW as it establishes the starting point for the welding process, allowing the welder to manipulate the electrode’s position and angle for effective welding.

The other methods presented do not align with the practices specific to SMAW. Using a propane torch for preheating is not a standard initiation technique in SMAW, as the process relies on the arc generated by the electrode. Applying heat through a plasma cutter is related to a different cutting process altogether rather than welding initiation. Immersing the electrode in a molten bath does not apply because the electrode needs to establish an arc with the workpiece first before any melting can occur in the welding process.
