Any concerns with buying an old Miller Dialarc HF-P TIG welder?
For context, I’m a hobbyist, not a professional. I have several projects that require welding and most of my limited experience is with MIG, and lately mostly with a cheap flux core inverter welder. I found a Miller Dialarc HF-P on a local listing for $400. Listing says it works. Comes with a cooler and a bottle but the cooler needs a new hose (not sure if that’s something I can make or if it’s available after market, couldn’t find anything when I searched. So I want to know, what am I missing out on if I go for this vs a newer one at 2-4 times the price (used). I want to get an HF TIG because I tried Lift TIG and sticking/regrinding the tungsten was wasting most of my limited project time. And gas.
In my experience, tools used to be made better, but on the other hand this one is from the early ‘80s, based on the model number. Is it built like a tank and will last forever? Or is it probably a few hours from turning off forever?
