Factors that can hinder the striking of an arc:
- Insufficient voltage: The voltage between the electrode and the workpiece must be high enough to ionize the gap and sustain the arc. - Improper electrode gap: The gap between the electrode and the workpiece should be within the recommended range. - Excessive electrode wear: Worn electrodes can result in poor contact and reduced current flow. - Contamination of the electrode or workpiece: Grease, dirt, or other contaminants on the electrode or workpiece can interfere with the arc formation. - Shielding gas issues: In certain welding processes, shielding gases are used to protect the weld area from contamination. Insufficient gas flow or improper gas composition can hinder arc striking. - Poor electrical connections: Loose or damaged electrical connections can limit the current flow necessary for arc initiation. - Faulty equipment: Malfunctioning welding machines, torches, or cables can prevent the arc from striking properly. - Incorrect polarity: In certain welding processes, the polarity of the electrode and workpiece must be correct for proper arc striking. - Electromagnetic interference: External electromagnetic fields can disrupt the arc initiation process. - Humidity: Excessive humidity in the environment can make it difficult to strike an arc.
