Review on Hobart 770198 Regulator Flowmeter Carbon: Optimal Gas Control Solution for Precise Welding by Xiaomeng Chang

Bought to replace a damaged regulator on my MIG welder. I would give this product five stars but the first one I received was defective. It was dripping heavily out the side of the valve from the side of the bottle. Looks like the inlet tube wasn't pressed properly against the valve body. I tightened it a few times thinking it sealed pretty well, but after spraying 409 on it I saw where it was leaking. Revain was great in an immediate replacement. The new one has been working great for over a year now. I use it with 75/25 Argon/CO2 gas.
