Spotter electrodes and electrode holders are accessories used in automotive body repair, localised metal heating and spot welding. The Irankistai.lt range includes LOTA Industries carbon electrodes, copper electrode tips, round and pointed electrode heads, electrode holders and specialised pulling accessory holders. When selecting a part, consider its intended function, shape, mounting method and compatibility with the specific spotter.
Types of electrodes and holders
- Carbon (graphite) electrodes. Used for localised metal heating and shrinking when the spotter supports this function. LOTA Industries 979120 comes in packs of 5, while 979120x50 contains 50 electrodes.
- Carbon electrode holders. Designed to secure graphite electrodes. LOTA Industries 979122 is a brass holder with a side fixing screw.
- Copper electrode tips and heads. Used for appropriate spot welding operations. The range includes round and pointed electrode heads and the 979118 copper tip.
- Electrode holders. ARM260 is a set of two 260 mm spot welding electrode holders. Electrodes are not included.
- Pulling accessory holders. Model 979123 holds OT / Circle tips, while 979124 holds pulling stars. These are specialised dent-pulling accessories rather than conventional welding electrodes.
How to choose a spotter electrode or holder
- Intended application. For metal heating, select carbon electrodes specified by the equipment manufacturer. For spot welding, use the appropriate electrode type and contact shape.
- Electrode shape. Round and pointed heads provide different contact geometries. Match the selected shape to the welding task.
- Mounting and dimensions. Verify compatibility between the electrode, holder, connection and machine. Similar appearance alone does not confirm interchangeability.
- Package contents. Check the quantity supplied. For example, SSNAP and SSharp electrode heads are listed in packs of two, while ARM260 holders are supplied without electrodes.
- Equipment model. Some parts are associated with particular machines. For example, the 90EDSW contact head is listed for the 90E unit.
Electrodes for professional automotive body repair
During dent removal and sheet metal repair, selecting the correct electrode or holder helps provide suitable electrical contact with the workpiece. Carbon electrodes are used for localised heating, copper tips for specified spot welding operations, and dedicated holders for securing compatible pulling accessories. Suitability must always be checked against the machine instructions and the individual part specifications.
Before starting work, inspect contact surfaces, electrode condition, holder retention and electrical connections. Replace worn or damaged components. Follow the spotter manufacturer's operating instructions and use appropriate personal protective equipment.
Frequently asked questions
What is the difference between a carbon and a copper electrode?
In this category, carbon (graphite) electrodes are intended for localised metal heating and shrinking. Copper electrode tips are used for suitable spot welding operations.
Do all electrodes fit every spotter?
No. Check the intended application, dimensions, mounting arrangement and compatibility with the specific machine.
Are electrodes included with ARM260 holders?
No. The catalogue lists two 260 mm holders in the ARM260 set, but electrodes are not included.
How do electrode holders differ from pulling accessory holders?
Electrode holders secure the corresponding electrodes, while the 979123 and 979124 holders are used for OT / Circle tips and pulling stars.
