Welding Wire SG2 TYSWELD 1.2 mm flux-cored wire, 15 kg spool

TYSWELD SG2 welding wire, 1.2 mm diameter on a 15 kg spool, is a flux-cored filler wire designed for gas-shielded and self-shielded arc welding of carbon and low-alloy steels. The wire provides a stable arc and good deposition rate, intended for steel fabrication, repair tasks and general metal joining in workshops and on construction sites. Its construction supports consistent bead formation and proper mechanical properties in welded joints when applied with appropriate welding parameters.

Advantages

Flux-cored wire formulation delivers reliable arc stability and efficient metal transfer, enabling steady deposition and reduced spatter compared with some solid wires. The 1.2 mm diameter balances ease of feeding and penetration for medium-thickness steel, while the 15 kg spool size reduces spool changes during longer work sessions. The wire is suitable for use with both gas-shielded and self-shielded techniques depending on setup and shielding arrangements.

Suitable for

• General steel fabrication and structural welding
• Repair and maintenance of machinery and metal components
• On-site construction welding where portability and spool capacity matter
• Workshop projects requiring consistent bead quality on medium-thickness plates

When it may not be suitable

This flux-cored SG2 wire is intended primarily for carbon and low-alloy steels and may not be appropriate for welding stainless steels, high-alloy steels, or non-ferrous metals. For very thin sheet materials or precision cosmetic joints where minimal heat input and the finest bead appearance are required, a smaller diameter solid wire or TIG welding may be preferable.

Key specifications

• Wire type: flux-cored filler wire suitable for gas-shielded and self-shielded processes
• Diameter: 1.2 mm
• Spool weight: 15 kg
• Intended material: carbon and low-alloy steels
• Typical features: stable arc, good deposition rate, reliable mechanical properties

How to use

Use the wire with a compatible flux-cored welding setup or a MIG/flux-cored combination unit capable of handling 1.2 mm wire and the spool weight. Select appropriate current, voltage, and travel speed for the steel thickness being welded, and set shielding gas or nozzle configuration according to whether gas-shielded or self-shielded operation is used. Ensure correct polarity and drive-roll pressure for smooth feeding. Prepare joint surfaces by removing heavy rust, scale, and contaminants to ensure sound fusion and mechanical properties.

What to consider before purchase

• Confirm material compatibility — intended for carbon and low-alloy steels
• Verify your welding equipment supports 1.2 mm flux-cored wire and 15 kg spools
• Decide whether gas-shielded or self-shielded operation is required for your application
• Assess required mechanical properties and choose post-weld treatments if needed

Usage recommendations

For consistent results, match welding parameters to plate thickness and joint design, maintain clean joint preparation, and store the spool in a dry environment to prevent moisture uptake. When using gas-shielded mode, select the recommended shielding gas blend and flow rate for SG2-type flux-cored wires to optimize arc stability and bead appearance.
