Grounding

  1. Cadweld Demonstration


    Creating quality and reliable cable ground is an important part of the construction process. Using welding kits, like the Cadweld Plus Electronic Exothermic Welding Deluxe Kit can help ensure a proper, high-quality weld and keep you and your crew safe and productive on the job. This week our Gear Experts®  are going to break down how to use the Parallel Splice Mold and K-Cups from the Cadweld Plus Electronic Exothermic Welding Deluxe Kit to ground cable. For more information on the regular & plus kits, click here to check out a previous blog post.

    Cadweld Connections


     

    A Cadweld connection has a carrying capacity equal to or greater than that of the conductor and will withstand repeated fault currents without failing during operation. Cadweld connections also consistently exceeded IEEE® 837 2014 EMF test requirements and have been certified by an independent lab.

    Prep


     

    Prep is equally as important because it can prevent accidents from happening. To prep for the weld, be sure to thoroughly clean the mold and copper wires using an approved Cadweld Mold Cleaning BrushAdditional cleaning of the copper wire with a wire brush may be required to remove any grit or corrosion. Next, preheat the wire and the mold using a heat torch. This will get rid of any excess moisture that could negatively affect the weld quality. 

    Setup


     

    Once you have completed the preparation steps, it’s time to put everything in place to activate the weld. 

    Step 1: Start by placing both wires parallel in the mold and use the mold handle to clamp it shut. You should feel a click when the clamp is completely closed. 

    Step 2: Next, take some Cadwld Mold Sealer and fill the bottom opening of the mold so the weld material doesn’t escape when the chemical reaction starts. 

    Step 3: It’s important to remember that you want to make sure your mold is level so the welding material flows into the correct channels once it has been ignited. 

    Step 4: Then, place the K cup of welding material in the top of the mold with the ignition tab exposed. 

    Step 5: Attach the electronic igniter to that tab and close the top of the mold.

    Step 6: Step away from the mold and hold the operator button on the ignitor control unit until the ready light turns off. At this point, the reaction will occur.

    Step 7: After the reaction, allow 30 seconds for the mold to cool before removing it from the wires. 

    Now you have a permanent splice between the two copper wires. Below is a demonstration video where we go through these exact steps to create a weld. You can also check out that video by clicking here or going to our YouTube channel.

  2. Grounding with Cadweld: Regular vs. Plus Kits

    When it comes to grounding there is little room for error. The difference between a high quality weld and low quality weld can be the difference between life and death. This week we want to talk about Cadweld Grounding Kits and the benefits they can provide. Our Gear Experts® have put together the need to know differences between the regular and plus kits.

     

    Grounding with Cadweld


     

    You’ve got a job coming up where you are going to need to ground some cables and you’re looking for the best solution. Here at GME Supply, we’ve got a few different options that can get the job done. We have the Cadweld Plus Electronic Exothermic Welding Kit and the Regular Cadweld Exothermic Welding Kit. Each of these kits provides a range of molds, cleaning supplies, and weld metal shots.

     

    The Plus vs. The Regular


     

    Let’s start with a side by side comparison of the kits. As mentioned above each of the kits provides many of the same things. The big difference is how the units work together to create the weld and promote safety at the same time.

     

    The Shots

     

    The plus kit features convenient “k cups”. These shots of weld metal are prepackaged in a cup that fits nicely into the top of the mold. The best thing about these is that all you have to do is put it in the mold. You don’t have to open the cup or pour the weld metal into the mold, saving you time and materials. One shot equals one weld.

     

     

     

     

     

    The regular kit, on the other hand, features traditional shots of weld metal. These shots come in a plastic tube with a cap. You have to remove the cap and pour the weld metal into the mold. This can increase the amount of time spent doing this task in addition to the accidental waste of materials. Not only that, but sometimes one shot isn’t enough to get the weld metal to the top of the mold for ignition – which means you have to add more weld metal. One shot does not always equal one weld.

     

     

    The Igniter

    The plus kit features an electronic igniter. The electronic igniter attaches to the shot (k cup) on the little tab at the top of the cup. This ensures a solid connection. The igniter allows you to put a larger distance between you and the mold providing added safety. To use the igniter simply turn on the switch and your weld metal will ignite and weld your grounding connection.

    The regular kit features a flint igniter. This is your traditional igniter where you press a button to strike the flint and the sparks light the weld metal. With this igniter, you have to be extremely close to the mold which can increase risk on the job-site.

     

    Weld Quality

    The final comparison is weld quality. Because of the way the plus kit works there will be a higher weld quality. With the shot being contained in the k-cup you have a much higher chance of achieving 100% ignition. With the regular kit, on the other hand, the weld metal can get separated when being poured into the mold and reduce the amount of metal that is ignited.
