Why Buy Tecna Spot Welders?
Tecna is known worldwide for dependable spot welding performance. The built-in synchronous timer, compensation circuit, long-life F-class insulated transformer and adjustable electrode force deliver reliable, repeatable welds across a wide range of materials.
Whether you need a simple, lightweight 2 kVA unit or a more advanced 2.5 kVA model with pulse and phase-shift control, Tecna offers professional results trusted in bodyshops and workshops across the industry.
A spot welder works by applying heat and pressure to two metal surfaces at their contact point. Electric current flows through the electrodes, generating heat that melts the metal, creating a weld. Once cooled, the metals bond together securely.
How much is a spot welder?
The price of a spot welder can vary significantly based on the brand and specifications. Generally, you can expect to pay between £200 and £2,000 for a quality spot welder in the UK. For professional-grade models, prices may exceed this range.
How to check spot welding strength?
To check spot welding strength, perform a peel test by applying force to separate the welded parts. Alternatively, use a tensile test to measure the maximum load before failure. Inspect the weld for uniformity and ensure proper electrode pressure and current settings were used.
How to use spot welding machine?
To use a spot welding machine, first ensure the machine is properly set up and connected to power. Position the metal pieces to be welded together, then align the electrodes. Activate the machine, applying pressure and current for a few seconds until the weld forms. Release and inspect the joint.
What is a spot welder?
A spot welder is a type of resistance welding machine used to join two or more metal surfaces by applying heat and pressure at specific points. It creates strong, localized welds, making it ideal for manufacturing processes in automotive and metal fabrication industries.
What is a spot welding?
Spot welding is a process used to join two or more metal sheets together by applying heat and pressure at specific points. This is achieved using electrodes that deliver an electric current, creating a weld nugget at the contact points, ensuring a strong bond.
