Product details

Weldmix 2% CO₂ gas cylinder, filled with 20L of AR CO₂, specially developed for welding stainless steel (designed for long-term and professional use).

Transport & Use:

  • Fixation: Because of the weight of a B20, it is essential to secure it in a vehicle with ratchet straps at two heights.
  • Transport: Always transport without a pressure regulator and with the metal protective cap on the cylinder.
  • Storage: Preferably store the cylinders vertically in a dry, well-ventilated area, protected from direct heat.

Specific safety information for Weldmix 2% (B20):

  • Asphyxiation hazard: Argon is heavier than air and displaces oxygen. When using a B20 cylinder in a relatively small space (such as an enclosed welding booth), good mechanical ventilation is an absolute safety requirement.
  • Pressure regulator: Use only a regulator for mixed gas. Since the cylinder is under high pressure, a good flow meter is essential to correctly set the gas consumption (liters per minute).
  • Mechanical safety: Although the B20 is more stable than smaller cylinders, the weight when filled is substantial. Use a proper welding cart with chain fixation to prevent tipping.
  • No grease/oil: Ensure a clean environment. Oil or grease at the valve connection can lead to contamination of the gas, which directly affects the quality of your weld.
