Do you guys agree no need to pull the plug then and if it is drawing 20 amps it has to be getting hot?
Where could that energy be going if not into heating the tip?

If the GP is faulty it can draw the correct current & all the heating is occurring it the part under the bolt fitting. I have seen this.
I cant understand why so many are pre-occupied in using a test meter, you are trying to see if the GP gets a proper glow pattern, you need to see it going red. You also need to make sure the GP hole is clean & doesnt require reaming. No test meter can determine this. Its time to get your fingers dirty!!
