Most modern automatic electric spot welders are built with extended longevity in mind, which means that you will get more years of enjoyment out of it before you have to replace it. They also tend to be made with parts that are extremely durable, and to last for many years. The welds that appear on metal objects are created by heating up the appropriate base metal (usually aluminum) and the joint that form between it and the work piece (the work wire). This process is extremely fast and produces a very strong weld. It’s important that you learn how to use the right equipment and operate it safely though.
The most basic types of automatic spot welding equipment includes tumblers and electrodes. A tumbler is just what it sounds like – a big container that holds tungsten (or sometimes other metals) in a very loose configuration. Electrodes work by allowing current to travel between the tumbler and the welding work. Different types of electrodes are available to suit different metals that need to be welded. Generally you can weld any size metal in a matter of seconds with a tumbler, but you’ll need to make sure that you have one that fits your needs.
There are a variety of different types of electrodes available as well. These include tungsten, copper, lead, stainless steel, and zinc. Some of these different types of electrodes are more suitable for certain welding processes, so it’s worth shopping around for the best deals. Some of the different types of electrodes are described below. While they may not be the same as the different types of welding electrodes available, they are still very useful for various different welding processes.
The first type of tumbler is called a spool. These are commonly used with three or four wire sections. These tumblers can be easily popped into place to cover small areas. A tumbler that is too small to fit into the required area will usually be insufficient to get the job done, and an automatic spot welding equipment dealer can tell you what tumbler is right for your needs. It’s often a good idea to buy a larger tumbler if you are making a large weld or covering a large area – this is because some welds can take a while to weld and will produce a lot of spatter.
The second type of electrodes are the slotted wire sections. These are commonly used with tungsten electrodes. Because of the way the slotted wires are positioned – rather than all the wires being connected in the same place – you can place these anywhere where you need them. This makes it very convenient to keep an eye on all of the wires at once, and is also less time consuming to weld when using the slotted electrodes. Because these types of welds are often easier to make, you will typically find that an automatic spot welding equipment dealer offers these more frequently. However, even with the convenience of using this type of weld, they are still more expensive than some other welds.
You can find these two types of electrodes in portable units. There are portable welders that you can take with you as you go from site to site, and there are also welders that you can assemble yourself at home. A portable unit that is designed for a single job may not be appropriate for a large job, and a portable unit that is designed for several jobs may also be inappropriate. If you choose an automatic welders, you will have to think carefully about whether you need this specific type of weld for a particular job, or whether you can use a different method.
