Good to know.. I will swap it out for a single turn.

Sounds like you are getting the high frequency starting arc but not the 
power.

I know that if I am stick welding and I have the high freq on, the the 
high freq arcs will jump between the electrode and ground but the power 
arc won't start until
I get the stick electrode closer to the workpiece.   When I get about 
1/4" from the workpiece the power arc will jump.

Perhaps you have a bad welding lead connection/bad ground or the voltage 
output is too low?

Thanks,

Dave
