Weldmix 15% AR CO₂ - B20
A Weldmix 15% B20 gas cylinder is a mid-sized, professional industrial gas cylinder with a water capacity of 20 liters, filled to 200 bar (or 300 bar) with a versatile MAG welding mixture. The composition of 85% Argon and 15% CO₂ is the most popular "all-rounder" for general construction work. The higher CO₂ percentage provides a powerful, hot arc that is ideal for welding thicker steel and construction work, while the Argon component ensures arc stability and spatter control.
The B20 cylinder is a popular choice for intensive users. It offers a significantly larger supply than the B10, increasing productivity by requiring fewer work interruptions for cylinder changes, without making the cylinder unwieldy or too large to handle.
Key features:
- All-round performance: Excellent penetration and stability for structural steel. It provides the ideal balance between an aggressive welding process (deep penetration) and a manageable weld pool.
- Higher autonomy: The 20-liter volume provides a significantly longer usage time, increasing efficiency in the workshop.
- Professional usability: Widely used in metal construction companies, mechanical engineering, and professional maintenance services.
- High-pressure system: Stable mixture in gaseous form, making the pressure on the manometer a reliable indicator of the remaining gas supply.
Product details
Weldmix 15%CO₂ AR CO₂ gas cylinder, filled with 20L of AR CO₂ (argon/carbon dioxide mix), specially developed for MIG/MAG welding (built for long-term and professional use).
Transport
Transport & Use:
- Vertical fixation: Transport and use the cylinder exclusively in an upright position. Secure the B20 in your vehicle using certified tension straps at two heights.
- Safety cap: Always screw the protective cap onto the cylinder when moving it. On a B20 cylinder, the valve is a vulnerable and costly component.
- Storage: Store the cylinders in a well-ventilated room, away from direct sunlight or extreme heat sources.
Safety
Specific safety information for Weldmix 15% (B20):
- Asphyxiation hazard: In the event of a leak in a poorly ventilated workspace, Argon and CO₂ can displace the oxygen in the air. Ensure continuous ventilation or use extraction systems directly at the welding source.
- Pressure regulator: Use only a pressure regulator for mixed gas. With this volume (B20), a stable regulator with a good flow meter (liters per minute) is crucial for a consistent result.
- Mechanical safety: A B20 cylinder has a substantial weight. Always use a stable welding cart with a proper chain or bracket fixation to prevent the cylinder from tipping over.
- No grease or oil: Ensure that the valve connection and your pressure regulator remain free of grease; this prevents impurities in the gas that could disrupt your welding process.
