Your torch angle is too much....the heat is being directed too far forward. Hold the torch more upright. (I think by thaw, you mean "melt"). You may also need a larger rod.

What are you using to clean the aluminum? Also you need to hold the torch abou 1/8" or less off the metal.

Sorry! Yes, is "melt". I have a 6 cup in my torch. Maybe i have too much gas flow (18 LPM) for this cup? I have 1/8" rods and for clean the aluminum i use a steel brush and acetone. Any other techniques? :-) I want practice again...

Thanks!
