Spot Welders

A spot welder is a resistance welding machine that joins two metal sheets. It uses heat generated by an electric current and pressure from copper electrodes. They're ideal for fast, clean welds on sheet metal, without the need for filler materials.

Spot welders are commonly used for mild steel, stainless steel, and galvanised steel. Specialised models or setups may also weld aluminium and copper-based alloys. You'll need to use appropriate settings and electrodes.

Most spot welders can handle materials between 0.5 mm and 3 mm thick. Some heavy-duty machines can weld stacked sheets or thicker components. This will depend on power output and electrode design.

You can buy a range of spot welders, the most popular include:

• Pedestal spot welders for stationary use
• Portable, handheld spot welders
• Inverter-based and MFDC (mid-frequency) spot welders
• Aluminium spot welders
• Spot welders for automotive applications
• Batter tab spot welder machines
• Single-sided spot welders 

We offer both new and used machines, all used machines are tested and serviced. Supplied with warranties as standard, unless otherwise stated.

AC (alternating current) spot welders are traditional, cost-effective machines suitable for basic applications. MFDC (mid-frequency direct current) models offer more consistent welds, faster cycle times, and lower power consumption. Making them ideal for production environments.

Water-cooled spot welders are recommended for high-duty applications, or when welding thicker materials. They help extend electrode life and improve weld consistency during continuous use.
