ESAB OK 48 zváracie elektródy, 2,5 mm, 4,3 kg balenie

ESAB OK48 2.5 mm welding electrode supplied on a 4.3 kg spool is a pink-coated solid electrode intended for manual arc welding setups that accept spooled electrodes. The product is formulated to provide consistent feed from the spool and predictable arc characteristics for fabrication, repair and maintenance operations where OK48 electrode chemistry and diameter are specified. The spool format simplifies handling and reduces changeover time in compatible welding feeders.

Advantages

The pink coating protects the electrode during storage and handling and enables smooth feeding from the spool. The 2.5 mm diameter balances deposition rate and control for general-purpose welding, while the 4.3 kg spool offers extended runtime compared with smaller spools. Consistent wire diameter and coating quality contribute to stable arc performance and reproducible welds when used with appropriate equipment and parameters.

Suitable for

• General fabrication and structural welding where OK48 chemistry is recommended
• Repair and maintenance tasks on machinery, metal structures and components
• Workshops using spool-fed manual arc or semi-automatic welding systems compatible with 2.5 mm electrodes

Key specifications

• Electrode type: solid, pink-coated
• Diameter: 2.5 mm
• Spool weight: 4.3 kg
• Form: spool for continuous feed
• Intended process: manual arc welding with spool-feed capability

How to use

Install the 4.3 kg spool into a welding feeder compatible with 2.5 mm electrodes and route the electrode according to the feeder manufacturer's instructions. Set welding parameters (current, voltage, polarity, and travel speed) appropriate for the OK48 electrode chemistry, base material and joint configuration. Maintain proper contact tip-to-work distance and observe arc stability; adjust feed speed or amperage to eliminate spatter and porosity. Store leftover spool in a dry environment to preserve coating condition.

Recommendations

Use appropriate personal protective equipment and follow safety guidelines for arc welding. Verify compatibility of the spool-fed electrode with the feeder and torch in your setup before extended runs. For best results, test welds on representative material to fine-tune parameters and ensure desired mechanical and appearance characteristics.
