How to operate the CD stud machine

How to operate the CD stud machine

Flash stud welding (CD stud welding) instantaneously discharges and welds the electrical energy accumulated in the capacitor to the stud bolt.

Welding can be completed siply by inserting the stud bolt into the chuck at the tip of the gun, pressing it against the base material, and pressing the switch.

Basic operation

Set of stud gun tip / Set of chuck, hexagon holder and stopper
  1. Set the screw type stopper in the hexagonal holder.

    (1) When welding a male threaded stud M3 to 6, screw in the end of the stopper with a thin end from the M8 side of the hexagonal holder.
    (2) When welding a male threaded stud M8 to 12, screw the thick end of the stopper from the M8 side of the hexagonal holder.
    (3) When welding a cap nut (female threaded stud), screw the thick end of the stopper from the M8 side of the hexagonal holder, and screw the cap for the cap to the tip of the stopper.

  2. Set the chuck in the hexagonal holder.

    Screw the chuck into the M7 side of the hexagon holder.

  3. Adjust the stopper.

    Insert the stud to be welded into the chuck, adjust the stopper so that the distance from the tip of the chuck to the welding surface of the stud is about 2 mm, and lock it with the lock nut so that it does not loosen.

  4. Use a tool to tighten tightly.
  5. Screw the set chuck, hexagonal holder, and stopper onto the gun shaft.
  6. Use a box wrench to screw in tightly.

    (Be careful not to over-tighten it, as it will break. The tightening strength of the hexagonal holder is 3N/mm, and the breaking strength is about 6-7N/mm.)

  7. Place the pressure gauge on the gun stand and turn the gun ring to adjust so that the top surface of the pressure gauge and the stud welding surface (surface at the base of the protrusion) are level.
  8. Tighten the lock ring so that it does not loosen, and the set is complete.
  • About the tightening torque of the hexagon holder The tightening strength of the hexagon holder is 3N/mm.
  • Breaking strength is about 6-7Nmm.
Set to the main unit (stud gun, ground)
  1. Connect the stud gun and ground to the body.
    The cam lock of the stud gun is red, and the ground is black.

  2. Insert with the groove facing up.

  3. Turn counterclockwise to lock. Check for looseness from time to time.

  4. After setting the cam lock for the stud gun and ground,set the remote for the stud gun.

  5. set complete

Introduction

Do a test shot first.

Be sure to do this as it will greatly affect the work that follows.
Also, select the M3 straight bolt for the first bolt to try.

Prepare offcuts of the same material as the product.

If the plate thickness is thin, the base material will bend when strength is applied, making it difficult to judge whether the weld is properly done.

  • In the case of black scale, rough surface may result in poor weldability.
    In addition, since rust and the like can cause poor welding, it is necessary to scrape the surface of the base material with a sander.
    Even if the black scale is clean, the weldability will be better if the black scale is scraped off.
  • Since it cannot be welded to the painted surface, scrape off the paint with a sander.

How to weld

  1. Prepare the base material

    See here for welding methods for each base material.

  2. Set the ground to the base material

    Ground installation position (away from the welding point and away from each other.)

    Set the ground to the base material
  3. Press the stud gun against the base material

    Wipe off iron powder, dust, oil, etc. from the surface of the base material with a waste cloth.

    Press the stud gun against the base material
  4. Welding is completed by pressing the gun switch.

    Pull straight up and out.

    Welding is completed by pressing the gun switch.
  5. Do a strength test

    First, visually check that there is no continuous gap between the stud bolt and the base material.
    If there is no gap, go to the next step.
    If there is a gap, adjust it and try again.

    Hold the stud bolt up to the base with pliers or pliers, tilt left and right, and repeat until the bolt breaks.

    If the stud bolt breaks, weld about 10 more bolts and repeat the strength test in the same way.
    If all the bolts are broken, the setting is complete. Welding is possible by adjusting the voltage when the size of the bolt changes.
