Step 1: Clean the electrode tips to ensure good conductivity.
Before starting the machine each day, use fine sandpaper or a dedicated electrode grinder to polish the surface of the electrode tips, removing oxide layers, metal debris, and oil stains until a clean metal surface is exposed. If the electrode tips show severe wear or deformation (such as end face indentation or increased diameter), replace them with electrode tips of the same specifications.
Purpose: To prevent excessive contact resistance from causing abnormal welding sparks and unstable weld nuggets.
Step 2: Clean the workpiece contact surface and workbench.
Use a brush or compressed air (pressure ≤0.5MPa) to clean metal splashes and dust from the workbench surface; regularly wipe the tooling fixtures with a cleaning agent to remove oil stains.
Purpose: To prevent impurities from affecting workpiece positioning accuracy and to prevent oil stains from adhering to the electrode tips and exacerbating wear.
Step 3: Check electrical connections to prevent loosening and overheating.
Weekly, check the welding machine output cables, copper bars, and terminals, and tighten any loose bolts with a wrench; observe whether there are any blackening or overheating marks at the connections. If there is oxidation, polish the area and apply conductive paste.
Purpose: To ensure stable current transmission and prevent welding machine failure or reduced welding quality due to poor contact.
Step 4: Check the pressurization system to ensure uniform pressure.
After starting the machine each day, perform a no-load test of the electrode pressurization action: observe whether the electrode moves downwards smoothly without jamming or abnormal noise; use a pressure gauge to randomly check the electrode pressure to ensure it matches the set value (deviation ≤5%). If it is a pneumatic pressurization model, check the air pipes for leaks and ensure the cylinder piston is clean.
Purpose: To prevent uneven pressure from causing weak welds and spark splashing.
Step 5: Check the cooling system to prevent equipment overheating.
Daily, check the cooling water tank level to ensure sufficient water and clean water quality; check the inlet and outlet pipes for blockages or leaks to ensure normal cooling water circulation. Clean the water tank filter screen weekly, and replace the coolant monthly (or according to the schedule specified in the equipment manual).
Purpose: To promptly dissipate the heat generated by welding, prevent overheating damage to the electrodes and transformer, and extend the equipment's lifespan.
