ABI introduces the Mini Pulse III (A), a new pulse-arc-welder to their line of tack-fusion-and pulse-arc-welding equipment. The Mini Pulse III delivers 17,000 mics of energy, capable of producing 1 pulse of energy per second as compared to the ABI Pulse-Arc-Welder that delivers 27,000 mics of energy and is capable of producing 2 to 3 pulses of energy per second. The Mini Pulse III has a dial voltage adjustment and 6 levels of energy controlled by toggle switches.
The ABI Mini Pulse III comes with an argon gas regulator (B), the Opti-saver instant darkening flash shield (C), 3 different size welding tips with two sizes of electrodes, brass lined pliers, brass tweezers, an alligator clip, contact pad, welding pencil holder and foot pedal (D) for $2,700.00. ABI also sells the unit without the argon gas regulator or the Opti-saver shield for $2,450.00.

| ||The connecting post and dangle jump rings were not soldered when originally made. |
One of the dangles has become unattached to the post (E).
| ||The jump rings are straightened and re-attached to the dangle portion of the earring (F). |
| ||The welding pencil is secured to the holder with the #2 welding tip (G). It is attached to the positive terminal of the Mini Pulse III. |
The alligator clip lead is attached to the negative terminal and clip it on the earring.
| ||The Mini Pulse III is set to 35 volts and on the 4 power level of energy set by the toggle switches. Levels of energy are activated when and the toggle switches are in the up position (H). |
The indicator lights (I) come on confirming that level of energy is activated.
| ||The jump ring is about one half millimeter away from the welding tip. |
It’s not necessary to remove the cultured freshwater pearls since the energy for welding is instantaneous and will not cause damage to them.
| ||The pulse of energy is directed to the joint on the jump ring. The welding has occurred on the side of the jump ring facing the welding pencil tip. |
The jump ring is rotated to complete the welding.
| ||The surface residue was generated by the welding procedure and polishing with rouge easily removes it. |
Tack-, fusion- and pulse-arc-welding equipment settings will differ and are based upon the volume, amount of contact and alloy of the material you are working with. Practicing using like materials will give you a parameter for the settings required for your application. Keep a record of settings and tasks for future reference.
