Sealey Large Opening Spot Welding Arms 500mm

About this tool

The Sealey Large Opening Spot Welding Arms are heavy-duty replacement components designed for automotive and metalworking spot welding applications. Compatible with Sealey SR122 and SR123 spot welders as well as other brands, these 500mm arms provide extended reach for accessing difficult welding positions on vehicle panels and larger metal assemblies. Each set includes electrodes and cotter pins for immediate installation, eliminating the need for separate component purchases. The substantial construction ensures reliable performance under workshop conditions, whilst the 500mm length offers the necessary clearance for working on bodywork repairs, panel replacement, and structural welding tasks where standard arms cannot reach. To maintain optimal welding performance and tip condition, the use of an electrode sharpener is recommended. Regular tip maintenance ensures consistent heat transfer and weld quality across multiple applications. The arms are supplied with compatible electrodes (model numbers 120/690048 and 120/690050), making replacement straightforward when required.
