Connecting your Spot Welding Pen:

  1. Before welding, polish the joint plane of the welding pen with fine sandpaper to expose the metallic sheen. To prevent surface oxidation, apply traces of lubricating oil on its joint plane.
  2. In a similar fashion, process the plane of the copperhead spot welder by discharging.
  3. Attach spot welding joints to the universal pen with internal M4 SHCS, ensuring M4 screws are tightly fastened for reliable electrical conductivity.
  4. Connect the welding power supply to a dedicated power outlet, avoiding power carriages since inadequate power supplies can negatively impact welding effects.
  5. Note that the pen-specific spot welding electrodes can reach up to 0.65 meters X2, affecting the welder’s original pulse discharge power. If you cannot stream to the first wife welding, you’ll require nearly double transfer of the spot welding current series.
  6. After the ph1.5 Anodized aluminum solder pins lose their shine, use a jig to forcibly extricate them. Remember to press the new welding needle to the bottom of the weld when replacing it.
  7. To maintain the quality of spot welding, ensure the welding tip is kept free from oxides.
