Instructions for Tack I & Tack II

Back to Tacking Machine Page

Section A
Setup Procedures and Requirements

1. Electrical requirements: please check the welder identification label to insure you have the proper voltage requirements for your power supply. Tack II welders are configured for either 100/120 volt or 208/240 volt single phase operation, 50/60 hertz/cycle. If by chance you have ordered or received the wrong voltage requirement for your area, do not plug the welder into your outlet. Contact the factory or your representative in order to receive the proper welder with the correct voltage requirement. Once you have checked for the proper voltage, please inspect to insure your power outlet is earth grounded. The Tack II welders will not function properly without the three prong earth ground power supply in your factory. It is further recommended that no other machines which have electrical current surges or heavy electrical line demands be plugged into the same power line source as your Tack II welder. Such other machines may cause the welder to fluctuate and/or may cause the welder to be damaged electronically.

2. Position your welder: at the rear of your work bench. Leave enough room at the front of the bench to place your contact pad or work station. Insure that the welder and work station area are set upon a wooden or plastic work surface. Do not use a metal top bench without plastic or wood on the weld area.

3. Plug the welder into your properly grounded electrical outlet with the proper voltage supply. Turn the power switch on. The indicator light should come on within a few seconds or the voltage meter will indicate a volt reading for models i and ii. If there is no indication of power on, unplug the welder from your outlet and remove the welder box cover. Please turn to the troubleshooting section of this manual for instructions.

4. When the power is on: and the voltage adjust knob is functioning on the front control panel, connect the two electrode tools you have chosen to the black and/or red connectors on the front control panel. You have optional electrode tools to choose from on the price list or you may make your own. Standard tools available are the contact pad work station, weld pliers, weld tweezers, touch weld pencil, as well as fusion weld collets of various types. Plug the foot switch pedal into rear of the welder box to complete the welder setup for the Tack II

Section B
General Operating Controls

1. Power switch: located on the front panel, switch the power on and wait for the charge indicator lamp to come on or voltage to register on the voltmeter. Discharge the welder to zero by making firm contact between your positive and negative electrode tools and depressing the foot switch.

2. Voltage control regulator: (potentiometer) allows you to select the amount of dc voltage at the weld surface. Selecting the proper amount of voltage is accomplished through trial and error. If you select too little voltage you will not weld. If you select too much voltage you may burn the pieces you are trying to weld. Practice with scrap metal before trying to weld quality pieces.

3. Energy selection switch: is standard on all our tack welders except the small Tack I. The energy equals (amps) at the weld surface. Please note the welder should be turned off when selecting a different energy range. This will prevent the burning of the selector switch contacts.

4. Foot switch: all our tack welders are foot switch operated. The Tack II and I Models have the ability to be weld discharged by holding the foot pedal down and striking the two electrodes (work pieces) together. This mode of operation is used for tacking together two work pieces. But primarily it is used for fusion welding to create an instant discharge at the work surface. Use low power and low voltage settings when using this mode. Caution: when the foot pedal is depressed, the electrodes are live electricity. Please wear protective gloves to guard against shock or insure you do not touch medal portions of the electrodes.

5. Indicator charge light: on the Tack I & II, you have the charge indicator light which tells you when the welder is ready charged for use. The higher the voltage selection the longer it takes the charge light to recover and come back on after each weld discharge.

Warranty

Upon receiving your tack welder, please inspect the crate thoroughly for any visual damage. It is your responsibility to notify the carrier and/or insurance agent for the carrier if there is any damage whatsoever to the crate, box or its contents.

All parts and/or components are warranted for a period of one year from the purchase date, fob the factory. This does not include consumables.

Shor does not warranty such consumable parts as ceramic tips, electrodes, contact pads or the like.

Shor does not assume any responsibility for damage in shipment, damage due to misuse, lack of proper maintenance and/or damage resulting in the operation of the welder in a manner not described herein.

Shor will no be liable for loss of profits, loss of use during repair or consequential damage of any kind which may arise from the general use of the equipment.

This warranty is in lieu of all other warranties expressed or implied, including without limitation warranties or guarantees of mechanicablility or fitness of purpose, which all other warranties are hereby expressly excluded.

Caution: always wear eye protection when using any welder of any kind. We firmly recommend wearing rubber gloves at all times to prevent electrical shocks to welder operators. These shocks can be caused when an operator is touching the electrode metal surfaces rather than the insulated portion of the electrodes and/or is not properly grounded at the contact work surfaces.

Section C
Weld Setup and Test

1. Power switch on, indicator light comes on. Welder charged and ready after a few seconds.

2. Select energy switch by starting at lower settings and increasing to more energy as required. Note: Tack I has no energy selection switch.

3. Select the voltage on low at first and increase higher as required to weld pieces.

4. Test welding with steel pieces such as paper clips will allow you to get the feel of the welder without destroying good pieces. Use also scrap gold, silver and brass etc. For test welding to learn the welder's capabilities.

5. Hold pieces to be welded firmly against the contacts in order to make good electrical contact and more consistent quality welds.

6. When pieces are in the proper position, depress the foot pedal to create a weld discharge. In some cases, you may choose to depress the foot switch first and then bring your work pieces together.

Caution: we firmly recommend the wearing of rubber gloves at all times to prevent electrical shocks to welder operators. Shocks are caused when operators touch the metal areas of the electrode tools.

Please note: If all functions of the welder seem to be in order, but you are experiencing a problem, you may have a metal to metal weld application which needs our technical expertise or you may have a weld application which is not possible. If you encounter this problem, please send us test pieces for evaluation

Caution: always unplug the welder before servicing.

General Operation and Maintenance Tack I & II

1. Weld flash, carbon, slag and surface oxides: Keeping all weld surfaces clean of surface oxide and dirt or oil is a must in tack welding of any kind. Clean the weld surface. Insure all electrodes, weld pliers, tweezers, collets and contacts remain clean to insure good contact electrically.

2. Contact pad, weld pliers, tweezers or contacts: The weld contact surfaces must be kept clean in order to insure good electrical conductivity. If your work piece is being scratched or it is sticking to the electrode contact surfaces, you may find it necessary to use the carbon contact pad option or install carbon contacts or silver tip your pliers or tweezers to insure conductivity and thereby eliminating arcing and/or burning of your pieces.

3. Tacking work pieces together: The Tack I and Tack II were primarily designed to tack or touch weld pieces together to prevent their movement during the soldering operation. This tack welding process will eliminate the need of fixtures, clips, wire or jigs. Once they are attached they will not move during the soldering operation. The process of fusion welding with the properly nibbed findings and the appropriate optional fusion collets and fusion weld pencil will allow you to permanently finish weld such findings as threaded studs, tie tac nails, earring posts, joints, catches, pin backs, wire couplings or cuff link actions.

4. Quality welding/tacking: To weld consistently and weld good quality pieces takes practice. learning to use the proper tools and electrodes also takes time. We suggest that you practice with scrap pieces of metal using various energy and voltage levels. Practice will make perfect.

5. Test weld: Test weld by holding the positive connections electrode tool firmly against the negative electrode tool and depress the foot pedal. The welder should discharge and recharge when you release the foot pedal and separate the electrode tools. Now, using scrap metal pieces, you should begin to learn the welder parameter. Try different voltage settings with similar and dissimilar metals. Silver or brass will require higher energy settings than gold or steel. Practice makes perfect. If you cannot weld a specific application you have, contact the factory for assistance or send test pieces for evaluation.

6. Test weld using the pre-contact live mode: Set the energy on low and lower the voltage on the meter. Using two work pieces, one negative and on positive (held firmly for good contact). Step on the foot pedal first, then bring the two work pieces together. This will create a spark as you bring the two work pieces together and make the tack weld.

7. Use distilled water: Use distilled water on each weld surface at the point of weld to eliminate the carbon blackening of your work surfaces. This is very good to repair pieces.
