The difference between spot welders and spotters

Spot welders and spotters are two special tools that are used for professional welding work in mechanical engineering and metal construction as well as for bodywork repairs. Although they are both based on the resistance welding process, they differ significantly in their function, their area of application and the welding technology used.

Spot welder

A spot welder is used to permanently join metal parts. Its main function is to create stable connections by means of precise spot welds. This is done by holding two metal parts together under pressure and heating them locally with an electric current so that they fuse at the point of contact.

The main area of application for a spot welder is in industrial production. It is often used in the automotive industry, in car body construction and in sheet metal processing. Typical applications include the joining of car body parts, the manufacture of housings or containers and the production of sheet metal parts in production processes.

The spot welder's welding technology is based on the resistance welding process. This involves an electric current flowing through two electrodes that compress the material. The electrical resistance at the contact point generates the heat required to fuse the metals. After cooling, a strong welded joint is created.

Spotter

A spotter is specially designed for repairing damaged metal surfaces. Its main function is to repair sheet metal damage such as dents or dings in vehicle bodies. Pull loops or pins are welded onto the damaged surface using the spotter and the material is returned to its original shape.

Spotters are primarily used in workshops and by bodywork specialists. It is often used in the repair of accident damage or the restoration of classic cars. Spotters make it possible to correct minor deformations without removing the body parts, allowing work to be carried out quickly and efficiently.

The welding technology of a spotter is based on a modified form of resistance welding. Pulling eyes or pins are used as fixed points to work on the material with pulling devices or hammers.

Frequently asked questions

What do you need for spot welding?

Spot welding requires a spot welding machine with suitable electrodes and welding arms, a reliable power supply (230 V or 400 V, depending on the machine) and properly prepared metal parts that are electrically conductive. It is also important to wear the correct work protection, such as a welding helmet, gloves and fireproof clothing, as well as a well-ventilated working environment. Expertise in equipment settings and welding technology is required to achieve optimum results.

How high is the current used in spot welding?

The amperage used for spot welding varies depending on the model and application. The maximum welding power is usually between 13 kVA and 16 kVA and the exact amperage depends on factors such as the type of material, material thickness and the specific settings of the device. More detailed information can be found in the data sheet for the respective model.

What materials are spot welders and spotters suitable for?

Spot welders and spotters are suitable for materials such as steel, stainless steel, galvanised steel and aluminium. They are ideal for thin sheets up to around 3 mm thick, whereby clean and grease-free surfaces are crucial for optimum results. Galvanised and painted sheet metal can also be processed. Aluminium requires special settings due to its high thermal conductivity. Spotters are particularly suitable for car body panels and spot repairs.

How do I properly care for and maintain a spot welder or spotter?

The care and maintenance of a spot welder or spotter includes regular cleaning and the replacement of worn electrodes. Maintenance intervals for the cooling system (for water-cooled devices) should be observed and the coolant replaced if necessary. Keep the appliance free of dust and dirt, especially in the area of the ventilation slots, to prevent overheating. An annual inspection by qualified specialists helps to extend the service life and maintain safety.
