How Should A Spot Welding Machine That Hasn't Been Used for A Long Time Be Stored To Prevent It From Breaking Down?

A spot-welder is a precision combination of power electronics and mechanics; if it is shelved for months without proper storage, you can expect aged boards, seized slides and erratic weld performance when you finally press the trigger again. Good storage practice is cheap insurance: it stretches machine life and guarantees that the first weld after lay-up is as good as the last one before shutdown. The rule of thumb is simple—clean, dry, anti-oxidant, periodic care and intelligent power-down.
1. Clean first, protect second
Before you switch off for the last time, clean everything: housing, arms, electrodes, coolant hoses and air vents. Remove dust, oil film and metallic powder. Wipe the electrode faces and coat them with a thin film of anti-oxidising oil. Mask power sockets, the HMI and any open connectors; cover the whole set with a dust-proof hood or plastic sheet. Park the machine in a dry, ventilated area so that transformers and PCBs never absorb moisture.
2. Keep moisture and oxygen away
Humidity is the No. 1 enemy. Keep relative humidity below 50 %, temperature stable, and avoid direct sunlight. Smear anti-rust oil or oxidation inhibitor on electrodes and all ferrous moving parts; add a drop of way oil to pivots and slides so they cannot seize. If the cooler is water-cooled, drain the circuit completely or fill it with anti-freeze/corrosion inhibitor to prevent internal corrosion or scale while the machine sleeps.
3. Scheduled inspection and “wake-up” power-on
Even when the line is down, give the welder a 10-minute health check every 4–6 weeks:
Inspect cables, lugs, switches and the HMI for looseness or corrosion.
Move arms and electrode holders by hand; re-lubricate if they feel dry or tight.
If plant power is available, energise the machine for 5–10 min—just enough to let the inverter, contactors and cooling fan spin. This keeps electrolytic capacitors formed and bearings free.
Do not leave the electronics totally cold for half a year; if full shutdown is unavoidable, disconnect the heavy-current bus but leave the control supply live when possible—your power modules will age far more slowly.
