I did take a look at the 211 last night.
My suspicion is the same that the switch is faulty. If I get a longer moment this evening, I’ll check the connector with a volt meter or try plugging in the switch from the 212. A new switch isn’t all that expensive compared to a new torch handle, so I’m hoping that’s all it takes to fix it.
Also… I noticed someone turned up the pressure to the maximum on the tank… There shouldn’t be a reason to go past 20psi while mig welding.
