I just got my Powermax 85. I was reviewing the manual on the automatic versus manual air pressure control. Just curious, have you been running in automatic or manual? I noticed the 85 has a spring loaded electrode. When the arc starts and air flows the electrode raises upwards. I would think it could be a source of problems if it was allowed to get dirty and it stuck or moved up partially when the air pressure was applied? Maybe something to check?
Questions for Jim
In the Powermax manual it states that in automatic mode the air pressure is automaticly set based on torch type and lead length. Since there is no data imput by the user, I have to wonder how does the machine know what torch type and lead length are connected to it? Thanks,
