How to Maintain a Spot Welding Machine

A spot welding machine is commonly known as a fusion torch welder. This equipment is used in a manufacturing environment to weld together multiple piece metals together through the use of a welder known as a flux. Fusing the two metals together is a process known as spot welding. In most cases, a welder will place a welder known as a TIG (torque instrument) over the piece of metal that needs to be welded and make a weld.

When welding a piece of metal with the use of a spot welding machine, the welder will place the torch in a container that contains tungsten electrodes. Typically, these electrodes are held in place by a welding fluid that has been pumped in through a wire feed system. This fluid will contain the exact amount of tungsten needed for the job at hand. Depending on the type of electrode that is used and the temperature that is attained, the welding fluid can vaporize or become a gas.

After the welding point has been reached, a fan motor will begin to operate. This will produce the vacuum that is necessary to keep the metal from vaporizing or becoming a gas. As the welding point is reached, the current will become very strong and the fan will begin to turn. The current produced will be much higher than what is needed to weld the sheet metals together safely and efficiently. A current limit will be placed on the fan and if it becomes too strong, an arc will occur and a spark will occur in the process.

When this happens, the welder will experience an arc flash. This process is referred to as a cutback. It is not uncommon for manufacturers to add a layer of lead to the steel or copper that is used to make the sheet metals that are welded together. This is done to prevent excessive arcing and smudges from occurring when the sheet metal is turned by the welder. The spot welding machine has an arc flash reducer installed that limits the amount of times the welder can arc without causing the flash to occur.

There are a variety of different ways in which the amperage and duty cycle of the welding equipment can be adjusted. These adjustments are done on the manufacturer’s side of things and should be compatible with the welding shop equipment that is being used in the job site. The duty cycle refers to the amount of time that the machine will remain on during a job. This is generally longer than the amperage because more of the work that needs to be done will not be done at the same time. Amperage is usually adjusted so that the machine is working at its maximum capacity. There are some metals that are easier to weld than others and they require lower amperages in order to create a good weld.

The final thing to consider for the welding business is to take care of the machine. There is a variety of different ways that cooling will take place. Most machines will have their own dedicated cooling system, but there may be ones that are sold as part of a welding system and only need the machine to be cooled when it is being used. Quality welds are a result of having the proper amperage, electrode life, and cooling.
