How Does an Automatic Spot Welding Equipment Work?
Automatic Spot Welding equipment is now being used more frequently by welding contractors and fabricators in their work. This type of welding is done on mig weldments and TIG welds with the help of a weld gun. The automatic welding machine saves valuable time as well as energy of the welder. As welding is very hard on the muscles, manual operations are not possible when you are working on larger pieces. If your business demands a lot of manual operations, the best option is to go for an automatic welding machine.
Automatic spot welding equipment consists of two major parts – the welding gun and the power unit. The welding gun is the part that shoots the arc towards the welding area and maintains a continuous arc until the electrodes are connected. A battery is also used to maintain an electric current.
Most of the welders use one of three types of power units for automatic spot welding equipment – the non-feedback, feed-forward or the nickel strip feeding mechanism. The non-feedback type has no direct control over the arc. It simply transfers the energy from the arc to the welded area using some form of indirect feeding mechanism. In case of a feed-forward machine, the feed forward mechanism is similar to that of the electric motor of a car – the motor pushes the vehicle into motion in order to do the welding.
The auto spot welding equipment uses three types of electrodes – the base material, the welding electrodes and the welding fluid. The base is generally made up of steel or copper while the welding electrodes are nickel, titanium or lead. There are two kinds of feed mechanism – the direct feed system and the indirect feed system. In the direct feed system, the welding electrodes are fed into the machine by a wire feed mechanism. They are pushed down by a drum that moves back and forth inside the machine. The third kind of feed mechanism is the indirect feed system where a wire strip is passed through the machine along with the welding electrodes.
The main parts of the machine are the control unit, the charger and the power source. All these parts work together to regulate the working of the machine as well as to give it power. A battery automatic spot welding machine needs to be charged regularly and this can take place either by the user manually or by the use of a dedicated charger. Similarly, a power source needs to be attached to the machine so that it can be powered on. In case of a handheld machine, the battery powered machine will be able to work even without a power source.
Finally, an automatic spot welding machine can be used to weld a variety of different materials including stainless steel and aluminium. These types of welding equipments have become very popular with companies who want to reduce manual labor while they increase the productivity of their workforce. Apart from reducing manual labor, companies have also seen the benefits of reduced downtime for themselves when they have to run their machines in an emergency situation. Overall, a welding machine is very beneficial for a company whether it wants to increase production or save on manual labor.
