HF works, but Arc wont start !!!

[Gman]

This is the same problem I was having. The only way I can get a stars is to rest my cup on the work and roll my torch over till the tungsten is 1/16”+/-. After I get a flame I can move the torch into position. Even doing this, sometimes I get the HF and no flame. I try and roll it closer and the spark will get so small you can hardly see it. And before you know it my tungsten is stuck to the work.
I don’t know if this is the right way to do it, as this is my first time using TIG.

Hi i have a power pro 205 and run the same issue a week before, turn out to be a defective foot pedal, works fine with the tig torch switch. Try it

My issue was on 2t, 2sec. pre flow, dc, 55-60 volts, no foot pedal.

2 seconds is a long preflow time. You are aware that the arc will not even try to start for two seconds from when you push the switch? The HF should be able to jump a gap of at least .125-.250". If it doesn't transfer to the main arc, check for possible ground issues. One person had the ground wire come out inside the rubber boot at the plug.

I've had the preflow all over the place. The 2 seconds is a +/-.
Yes, I can hold it 1/2" away and still get spark.
I'll have to check that.
