20 Cu Ft Steel Argon Cylinder With CGA580
This compact steel argon tank is designed for TIG and MIG welding across mobile and shop settings. It features a 2015 PSI service pressure, a lightweight 13.67 lb tare weight, and a 5.25″ diameter by 18″ height profile for easy transport. The new CGA580 valve supports multi-gas compatibility, enabling use with argon, nitrogen, helium, neon, and CO2/nitrogen mixtures. Standard 3/4″ NGT threading ensures broad regulator compatibility. The heavy-duty steel construction provides durability and a painted finish for longevity. DOT approval adds transport and storage safety assurances.
New 20 Cubic Foot Steel Nitrogen Cylinder
This DOT-3AA compliant nitrogen cylinder is built from high-strength alloy steel with thick walls, designed for durability in manufacturing, HVAC, hydroponics, and beverage contexts. It ships empty, so coordinate with a local supplier for filling. The CGA-580 valve is pre-installed, maintaining compatibility with standard nitrogen regulators at a service pressure of 2015 PSI and a test pressure up to 3365 PSI. The robust construction supports demanding environments while remaining suitable for portable use.
New 20 cu ft Steel Nitrogen Cylinder With CGA580
This 20 cubic foot nitrogen cylinder provides a dependable inert gas option with a CGA580 valve already installed. Its 2015 psi service pressure and 3000 psi test pressure support consistent regulator performance. The brand ARC UNION marks high-strength steel construction with a paint finish designed for long service life. It is a suitable choice for welding, metal fabrication, and other industrial applications requiring inert gas shielding.
Hot Max 23202 20 Cubic Foot Argon/CO2 Tank
This empty, factory-new cylinder is designed for argon/CO2 gas mixtures and is refillable and exchangeable. Its compact dimensions—approximately 5 by 5 by 18 inches—make it suitable for tight spaces and portable use. While the listing notes the tank as empty, it accepts standard gas fills from suppliers capable of argon-CO2 configurations, enabling ready deployment for TIG, MIG, and related welding tasks when filled.
60 Cu Ft Steel Argon Gas Cylinder
Offering a larger capacity, this 60 cubic foot argon cylinder balances high gas volume with portability at a tare weight around 29 lb. The CGA580 multi-gas valve supports various inert or shielding gas configurations, including argon, nitrogen, helium, neon, and CO2/nitrogen mixes. The robust steel cylinder features a painted exterior for durability and ISO USA stamping for compliance with US transport standards. It is suitable for professional welders needing extended run times between fills.
ARCCAPTAIN Argon CO2 Regulators Gauges Gas Welding
Although a regulator rather than a tank, this ARCCAPTAIN unit is relevant for regulators used with CGA580 tanks. It supports argon, helium, and carbon dioxide, with an inlet range of 0-4000 PSI and output ranges up to 30 CFH for argon or 20 CFH for CO2. The brass body includes a pressure relief valve and an inline filter to extend regulator life and improve welding consistency, making it a practical companion for argon gas systems.
Buying Guide: Key Considerations for 20 Cu Ft Argon Tank Purchases
- Valve compatibility: Most 20 cu ft tanks use CGA580, which is common for argon, nitrogen, helium, and CO2 mixes. Confirm your regulator or welding machine accepts CGA580.
- Service and test pressures: Look for cylinders with service pressures around 2015 PSI and test pressures around 3000–3365 PSI to ensure regulator compatibility and safety margins.
- Content and gas type: Pure argon tanks are ideal for TIG welding, while nitrogen and CO2 mixes suit different shielding needs. For aluminum or magnesium, argon is typically preferred; for carbon steel, argon/CO2 blends can be used in some contexts.
- Portability and dimensions: Consider tare weight and overall size. Lighter bottles with manageable height are easier to transport between jobs and to store in small shops.
- Certification and safety: DOT or ISO stamping indicates compliance with transport and storage regulations. Verify cylinder is certified and not past hydrostatic test dates if visible.
- Refilling and availability: Some listings ship empty; plan for reliable local suppliers to fill the cylinders and verify fill compatibility with your regulator.
- Regulator compatibility: Ensure your regulator’s inlet is CGA580 and that the regulator flow rate meets your welding requirements (e.g., shielding gas flow rates for TIG/MIG).
- Usage scenario: For mobile welding, prioritize compact, portable cylinders; for shop work, a larger capacity like 60 cu ft can reduce frequent refills, provided transport and storage space are available.
- Quality and brand reliability: Steel cylinders with strong construction and durable finishes tend to provide longer service life in rough environments.
