MIG/MAG and TIG Gas Saver DONMET Optimizer DM Lite

Reduce shielding gas consumption by 30–50% with a gas saver designed for MIG/MAG and TIG welding. The device eliminates the sudden pressure surge at arc start, ensuring a stable flow rate and constant pressure during welding.

Key Benefits

✔ Gas savings of 30–50%
✔ Stable and controlled gas flow
✔ Reduced gas loss at every arc start
✔ Very easy installation – simply screw it onto the regulator outlet
✔ Fast return on investment through lower gas consumption

How Does It Work?

During MIG/MAG or TIG welding, the regulator maintains the preset gas pressure and flow rate. At the end of each welding cycle, the machine’s solenoid valve closes, but gas pressure continues to build up in the hose between the valve and the regulator.

When welding restarts, this accumulated pressure is released as a sudden surge, causing unnecessary gas waste.

The gas saver:

• Controls the delivery pressure of the shielding gas

• Prevents excessive gas build-up in the supply hose

• Minimises pressure spikes at arc ignition

• Maintains a consistent flow rate without affecting weld quality

An ideal solution for workshops and industrial environments looking to reduce operating costs and improve welding efficiency without changing machine settings.
