10 Professional Servicing: If any issues arise or if the welding machine requires repair or servicing beyond
routine maintenance, consult a qualified technician or service provider. Avoid attempting repairs or modifications
unless properly trained and authorized.
Arc Welding Accessories:
• Electrode Holder:

- Inspection: Regularly inspect the electrode holder for signs of wear, damage, or overheating. Check the jaws
for proper alignment and functionality.
- Cleaning: Keep the electrode holder clean by removing any spatter, flux residue, or debris that may accumulate
during welding. Use a wire brush or compressed air to clean the jaws and contact surfaces.
- Replacement: Replace worn or damaged electrode holders promptly to maintain a secure grip on the electrode
and ensure a stable electrical connection.
• Ground Clamp:
- Inspection: Periodically inspect the ground clamp for signs of wear, damage, or corrosion. Check the contact
surfaces for cleanliness and tightness.
- Cleaning: Clean the contact surfaces of the ground clamp and workpiece to ensure a good electrical
connection. Remove any dirt, paint, or rust that may interfere with conductivity.

- Replacement: Replace damaged or corroded ground clamps to maintain reliable grounding and prevent
electrical resistance.
• Welding Cables:
- Inspection: Regularly inspect welding cables for cuts, abrasions, or exposed wires. Check connectors and
terminals for tightness and corrosion.
- Cleaning: Keep welding cables clean and free from dirt, grease, or oil. Wipe down the cables with a clean, dry
cloth regularly to prevent contamination and maintain flexibility.
- Repair or Replacement: Repair or replace damaged welding cables promptly to prevent electrical hazards
and ensure reliable current flow.
• Shielding Gas Regulator and Hoses:

- Inspection: Inspect the shielding gas regulator and hoses for leaks, cracks, or damage. Check the pressure
gauge for accuracy and proper functioning.
- Cleaning: Clean the regulator and hoses regularly to remove dirt, dust, or debris. Check hose connections for
tightness and security.
- Leak Testing: Perform leak tests on the regulator and hoses periodically to ensure that there are no leaks in
the gas system. Use a leak detection solution or soapy water to identify leaks and repair them promptly.
• Welding Helmet:
- Inspection: Inspect the welding helmet for cracks, damage, or signs of wear. Check the filter lens for scratches
or discoloration.

- Cleaning: Clean the outer shell and lens of the welding helmet regularly to remove dirt, spatter, or debris.
Replace the filter lens if it becomes scratched or obstructed.
- Adjustment: Ensure that the welding helmet fits securely and comfortably on the operator’s head. Adjust the
headgear and straps as needed for a proper fit.
• Protective Clothing and Gear:
- Cleaning: Clean protective clothing, such as welding jackets, gloves, and aprons, regularly to remove dirt,
grease, or welding spatter.
- Inspection: Inspect protective gear for signs of wear, damage, or deterioration. Replace any worn-out or
damaged clothing or gear to maintain adequate protection.

- Storage: Store protective clothing and gear in a clean, dry area away from heat, moisture, or sunlight when
not in use to prevent degradation.
