Welding Electrode ESAB ER 150, diameter 2.5 mm, 5 kg spool

ESAB ER 150 welding electrode in 2.5 mm diameter on a 5 kg spool is a solid filler wire engineered for manual and semi-automatic welding processes. The product is intended to provide steady deposition and reliable fusion characteristics for general fabrication, repair and maintenance work. Presented on a compact 5 kg spool, the wire is suitable for workshops and job-site applications where controlled feed and minimum handling are important.

Advantages

The ESAB ER 150 electrode offers uniform wire feed, consistent melting behavior and predictable deposition rates, which help reduce spatter and rework. Its solid construction and controlled dimensions simplify setup for both hand welding and mechanized feeders. Packaged on a 5 kg spool, it minimizes downtime from frequent reel changes and is convenient for mid-sized welding tasks.

Suitable for

• General fabrication and structural welding
• Repair and maintenance of steel components
• Semi-automatic MIG/MAG welding setups with 2.5 mm wire capability
• On-site welding where compact spool size and easy handling are required

Key specifications

• Wire type: solid filler wire for manual and semi-automatic welding
• Diameter: 2.5 mm
• Net weight: 5 kg spool
• Intended materials: carbon and low-alloy steels (general use)
• Format: spool suitable for wire feeders and hand-feeding

How to use

Load the 5 kg spool onto a compatible wire feeder or position it for manual payout. Match welding current, voltage and shielding gas (if applicable) to the ER 150 wire diameter and the base material; follow equipment manufacturer settings as a starting point and fine-tune parameters to achieve desired penetration and bead profile. Maintain clean joint surfaces and correct contact tip-to-work distances for consistent feed and arc stability. Store the spool in a dry environment to avoid contamination.

Usage recommendations

Use compatible wire-feed equipment rated for 2.5 mm wire and observe recommended welding parameters for carbon steel to obtain optimal deposition and minimize porosity. Rotate spools or inspect wire before use if stored for extended periods to ensure cleanliness and performance.
