Periodic inspection for solder pot

Solder pot is a consumable item.

Solder pot gets hole due to corrosion by solder after longtime use, and solder begins to leak.

  • If the solder amount decreases quickly, it may indicate solder leakage.

It is recommended to check the condition of the solder pot before work, and replace it with a new one if you see a problem for your safe and comfortable work.

How to confirm the pot's life

Make sure to do it when the pot is cool.

  1. Loose the screws on both side with the hex wrench supplied and take out the pot.

  2. Check the removed pot carefully for holes or solder leakage on the surface.

    Also, check the sides and bottom surface of it visually.

    Sample of pot corroded

    When the pot gets a hole due to corrosion, the solder slowly leaks out through the hole.
    (It never leaks out rapidly like water.)
    Pay attention to how the solder in the pot decreases on a routine basis.

    Replace the pot with a new one if you see any abnormality on the pot.

  3. Confirm that there is no solder leakage inside the unit.

    Confirm that there is no solder leakage around the heating element and heat insulators.

  4. If there is solder leakage, remove the solder.

    Scrape off the solder lightly with a spatula, etc., and remove solder waste come off.

    If you find solder leakage inside the unit, solder pot replacement is recommended even if no major defect was found during inspecing No.2.

    In case a lot of solder leakage cannot be removed easily by a spatula, etc., repair work may be necessary.

  5. Reattach the inspected pot to the unit, rotating 90 degrees from the original position.

    Turn the pot 90 degrees and install it so that the side that was contacted by the heating element is now facing the insulators.

    By rotating the pot surface to contact the heating element periodically, the pot can be used for a longer time.
  6. Tighten the screws on both sides firmly with the hex wrench supplied to finish the inspection.

    Make sure that the pot is fixed firmly.

    If the screws are not tightened enough, the heat cannot be transferred well.
