Portable Spot Welding Machines are ideal for companies that work on projects requiring frequent welding of several metals simultaneously. Portable welding machines are also called semi-automatic welders. Through heating and pressing the welding spot on a welding machine, portable spot welding machines are able to fuse several metal sheets permanently through heating and contact with the welding arc. The term portable idents in this welding technique refers to both the welding points where the heat and pressure applied are transmitted.
There are three types of welding techniques used with a hand operated welding machine. The first type is the MIG (Metal Inert Gas) welding technique. This is the most widely used welding technique used with the hand operated welding machine. MIG welding is a type of gas metal arc welding technique that uses a wire feed to provide power to the arc and also a taper into which the molten metal will cool and solidify. The taper on a MIG is controlled by a cut off switch located on the weld area.
The second type of welding technique that the hand operated spot welder is commonly used with is the TIG (Tungsten Inert Gas) welding technique. This type of weld uses a tungsten sleeve to create the arc that fuses the metal pieces. TIG is typically used when working with small diameters, low temperatures and low amperage or electric loads. The final type of welder we’ll discuss is the PZT (passive zirconium tungsten) welding technique. This is the most commonly used type of welding that is done with a hand operated spot welder.
A very popular hand operated welding machine today is the Portable Battery Spot Welding Machine. These are very compact, lightweight and take up very little space. Most of the time the welder is bolted to the workbench with a cable system so that the user does not have to worry about securing it to any surface. Many of the PZT welders actually use a push button to start the process so there is not much time involved once the welder is turned on. A typical positive control voltage is around 2.4 volts and a low amperage battery is used to power the weld chamber.
The next machine in our list of portable welding machines is the Crux welders. These welders are similar to most other welding machines in that they have the same control panel and some basic controls. They also come in both wet and dry varieties. The dry version is great for getting into places that may not have electrical power or a well-connected power outlet. The wet Cruxweld for a more accurate weld and can be used with all types of fuel.
This is the last of our portable welding machines. The Magna Cartridge Welder is a true gem. It is truly unique as it allows you to weld with the most current available in a portable cartridge. It takes less time to weld than most other welding machines, and it allows you to work in very tight spaces. You can even run multiple welding cycles on one charge!
