Portable Spot Welding Machines are used by many industries as an alternative to the more traditional power tools and plasma cutting equipment. In normal equipment, a huge transformer is your power source operating at high voltage and low current resulting in a huge and heavy portable welding machine, never suitable for smaller applications that require smaller and lighter units such as onsite maintenance tasks. This also means that a portable welding machine needs to be plugged in, and run by a separate generator or set of batteries. This also means that the portable welding machines cannot perform many tasks other than welding. This is not necessary with the portable spot welding machine and as it operates at lower wattage, produces smaller arc sizes, and the consumables used are not as expensive.
A portable spot welding machine is basically a portable welding station with a miniature metal arc produced by a gas fueled rod. The machine uses a clamp to place the welding area and the welding process itself, including position, feed control, and fan speeds, can be operated with one hand. It is especially useful for welding thin layers of metal quickly without requiring great effort, allowing operators to get on with other tasks, whilst the machine maintains a constant arc. Portable welders are used for many different industrial tasks including metal fabrication, airframe building, woodworking, dent repair, drilling, plumbing, automotive, electronics industry and more.
A portable welding machine offers many advantages over a standard model. The most obvious one being that it has a much smaller turning radius and much less overall weight. The reason for this is that the welder is not using a generator and does not generate its own power, but instead requires a battery and some sort of power input, such as an electrical plug, to operate. This makes the portable welding machine ideal for doing all but the smallest jobs, as it has no need for the operator to stand directly in front of the arc, and therefore no requirement for extremely strong or heavy welding equipment.
The machine is also incredibly easy to use, with many even having a touch screen for simple and quick navigation. In addition it has a very short lead time, meaning that operators can complete their work in record time. The light weight of the machine means that operators can move it about safely without any risk of it injuring itself. One of the most unique aspects of the portable spot welding machine is that it can accept both MIG and TIG welding processes. Because it uses an external electrical supply, it is completely safe to work on, and there is no need for the welder to ever leave its weld area.
MIG welding machines are also extremely popular, and are often the choice for many industries and construction projects because of their reliability and speed. MIG electrodes have excellent thermal conductivity, which means that they will hold a good temperature even when exposed to water or other liquids. This makes MIG welding machines ideal for making tig and arc welding connections in applications where you need a durable, robust product. The electrical current produced by the welding machine is generally higher than what would be required using a MIG connection, however, because the extra resistance comes from the heat sink and fan in the unit.
TIG spot welders use an electrode with a small flux hole and produce high quality welds that are difficult to obtain using MIG welds. TIG welds also require an external power supply, and the units are quite large, which limits their use to some extent. These welds are also extremely tough and durable, making them ideal for applications where the weld requires a tight, smooth surface to ensure that it fits firmly and is smooth and free of burrs. Portable spot welders provide high quality joints that can meet the needs of any type of job.
