I purchased a eastwood 175 mig 6 months ago. The welder performs great but uses more argon/co than any other welder I’ve ever used. The welder used 200cf of ar/co mix set at 20cfh before I went through the last 2lb spool of wire. I cannot hear any leaks within the welder and the post flow is only a few seconds. I’ve used 3 200cf bottles (@$96.00 each) in the last few months and have used less than 6 lbs of wire. Has eastwood had any problems the the regulators or welders leaking?
