Welding wire Tysweld SG2 0.8 mm 5 kg spool, solid CO2/MIG welding consumable

Tysweld SG2 0.8 mm welding wire on a 5 kg spool is a solid CO2/MIG welding consumable designed for gas-shielded welding of mild and low-alloy steels. The wire diameter of 0.8 mm and the 5 kg spool size make it suitable for steady feeding in standard MIG equipment. Tysweld SG2 is intended for general fabrication, workshop repairs and metal construction where a reliable, general-purpose steel filler metal is required.

Advantages

The wire provides consistent feedability on automatic and semi-automatic feeders and maintains stable arc characteristics across typical welding currents for CO2/MIG processes. Its composition is optimized for good bead appearance and predictable fusion on common structural steels. The 0.8 mm diameter balances deposition rate and control, allowing for efficient welding without excessive spatter when correct parameters are used.

Suitable for

• General fabrication and sheet-to-plate welding of mild steel
• Workshop repair and maintenance of structural components
• Metal construction and light structural assemblies
• CO2/MIG gas-shielded welding applications with standard equipment

Key specifications

• Wire type: solid, general-purpose mild/low-alloy steel welding wire
• Diameter: 0.8 mm
• Weight: 5 kg spool
• Process compatibility: CO2 and mixed gas MIG (gas-shielded arc welding)
• Typical feedability: suitable for automatic and semi-automatic wire feeders

How to use

Install the 5 kg spool on the wire feeder spindle, ensuring proper alignment and tension according to the feeder manufacturer's instructions. Thread the wire through the liner and contact tip sized for 0.8 mm wire. Select welding parameters—wire feed speed, voltage and gas flow—appropriate for CO2/MIG welding of the specific steel thickness. Maintain correct torch angle and travel speed to obtain consistent fusion and bead profile. Use suitable shielding gas (commonly CO2 or CO2/mixed gas) and ensure clean joint fit-up for best results.

Usage recommendations

For optimal performance, clean base metal surfaces of rust, oil and mill scale before welding, use contact tips and liners matched to 0.8 mm wire, and verify gas flow and polarity settings for CO2/MIG. Perform trial welds to fine-tune parameters for material thickness and joint configuration.
