Tips For Purchasing a Portable Spot Welding Machine
If you are looking into doing welding jobs that require the joining of two pieces of steel, whether they are hot rolled or cold rolled, you need to find a spot welder that can do the job. Spot welding is a method used to join different pieces of metal together, either manually by melting them together, or by welding them with a filler rod. The process usually produces a consistent, quality product, which is another big selling point of spot welding. Here are some tips that will help you find the right spot welding manufacturer.
When you start looking for a welder that can perform the welding job that you want done, you need to consider what type of metal you will be joining. Some types of metals, such as aluminum and steel, are stronger than others, so you may need to choose a different type of machine for the job that you want done. For example, a high output spot welding machine may not be the best choice for joining soft metals such as PVC pipes. You will also want to look at the maximum wattage that the machine is able to handle. Most units are designed to handle up to either 2200 watts or more. This is usually a good starting point in choosing a machine for a shop.
You should also consider the welding machine’s portability. A small, portable stainless steel machine is perfect for a do-it-yourself spot welding job in the home. However, if you have larger projects that require welding on a commercial scale, it would be better to consider a larger stationary machine. These larger machines are able to weld larger pieces of steel, and they have more powerful welds with higher amperage. In addition, they are often built with a variety of interchangeable parts, so you will always be able to find the part that you need for your welding project.
When you start looking for a new welding machine, make sure that you find a manufacturer that can deliver what you need without breaking your budget. It is always better to get price quotes from more than one manufacturer before making a final purchasing decision, as this can help you negotiate the best deal. If possible, visit a couple of different manufacturers to see what they have to offer, and get price quotes from each company before deciding which one to purchase from.
There are many features that you will want to take into consideration when choosing the right welding machine for your needs. One is whether you need a portable, high output machine, or a stationary, low output machine. Most people prefer to purchase a machine that is capable of working with both high and low amperage; however, if you are not going to be using a high output spot welding machine on a regular basis, then a lower amperage machine may be a better option. Another important feature is whether you are looking for a portable machine or one that can work in both the cold and hot areas. Cold welding uses arc energy, while hot welding uses spark plug energy.
Portable machines are best suited for small to medium-sized projects that don’t require a high amperage output. The best way to determine if a portable welding machine will be right for you is to ask yourself if you think you will ever be using a portable machine on a regular basis, or if you are only going to need to use it on special projects. Portable units are also typically lighter weight than the stationary versions, as well as being more portable. Finally, consider the type of weld you will need to complete; wet welds require that the weld area is kept moist until the surface is ready to accept the filler metal, and dry welds are performed when the filler metal is added to the molten steel. If you are familiar with both types of welds, then it will be easier to choose the right machine.
