The LINCOLN ELECTRIC 3000773 is a welding gas regulator designed to control and reduce cylinder pressure to a safe, usable working pressure at the torch or wire feeder. It accepts a CGA 580 inlet connection, making it compatible with argon, helium, nitrogen, and C-25 (argon/CO2 mix) cylinders. At 7.75 inches tall and 7.5 inches wide, the unit has a compact footprint suited for shop and field use. Welding technicians and fabricators install this regulator between the gas cylinder and the welding lead to maintain consistent shielding gas flow throughout the weld.
This regulator is intended for MIG, TIG, and related shielding gas applications where argon, helium, nitrogen, or C-25 blends are the supply gas. The CGA 580 inlet is the industry-standard connection for non-oxidizing, non-flammable compressed gases, covering the most common inert and mixed shielding gases used in professional welding environments. It is suited for both shop bench setups and portable cylinder carts in fabrication, maintenance, and repair operations.
Designed for use with compressed gas cylinders fitted with a CGA 580 valve, which is standard for argon, helium, nitrogen, and C-25 shielding gas cylinders used in welding applications.
Installation should be performed by a qualified welding technician or gas systems professional. Before connecting or disconnecting the regulator, close the cylinder valve and bleed residual pressure from the regulator body. Use an appropriate wrench on the CGA 580 fitting — do not use pipe thread sealant or PTFE tape on CGA fittings. Check all connections for leaks with an approved leak-detection solution before striking an arc.
