Welding Wire Tysweld SG2 1.2 mm 15 kg spool, flux-cored/solid filler for steel welding

Tysweld SG2 welding wire, 1.2 mm diameter on a 15 kg spool, is designed for manual and semi-automatic welding of carbon and low-alloy steels. The wire delivers consistent feed and a stable arc, suitable for general fabrication, repair and maintenance operations. Its characteristics make it appropriate for butt, fillet and lap joints in construction, workshop and light industrial settings where reliable weld quality and ease of use are required.

Advantages

The wire offers uniform wire feeding and good arc stability, reducing spatter and supporting smooth bead formation. Its 1.2 mm diameter balances deposition rate and control, allowing efficient welding on a range of material thicknesses. Packaged on a 15 kg spool, it is convenient for extended welding runs in workshop and semi-automatic setups. Compatibility with common welding equipment used for carbon and low-alloy steels ensures straightforward integration into existing workflows.

Suitable for

• Manual MMA and semi-automatic MIG/MAG welding of carbon steels
• Fabrication and structural welding in construction and workshops
• Repair, maintenance and refurbishment of steel components
• Butt, fillet and lap joints on low- to medium-thickness steel

Key specifications

• Wire type: solid/flux-cored filler suitable for steel welding
• Diameter: 1.2 mm
• Net weight: 15 kg spool
• Application: manual and semi-automatic welding processes
• Base material compatibility: carbon and low-alloy steels

How to use

Prepare base metal surfaces by removing rust, paint and contaminants to ensure proper fusion. Select welding parameters appropriate for 1.2 mm filler wire, including correct voltage, current and wire feed speed for the chosen process and material thickness. Install the spool onto the feeder, set the correct drive-roll tension and guide the wire smoothly through the liner to avoid birdnesting. Maintain suitable travel speed and electrode angle to achieve consistent penetration and bead shape, and allow welds to cool under controlled conditions when required.

Usage recommendations

Use shielding gas and process settings recommended for carbon steel to optimize arc stability and minimize porosity. Store the spool in a dry environment to prevent contamination. For critical or high-strength applications, perform pre-weld testing and adjust parameters according to workmanship standards and base material specifications.
