Vertical Up Tig Weld W/185 Micro on 11 Ga Aluminum
Thought i would try something today , I did some Heliarc a long time ago like this and wanted to see if my bad nerves and shaky extremities could be steady enough to run uphill .
Used the foot pedal to add the extra heat to get the puddle started. Machine set at 110 backed of to around 95 amps after the heat built up.I did several different setups and techniques. Dipping the rod gave you a wider puddle than i wanted and did not let you burn into the corner enough for my liking. The best result were from pushing the rod into the puddle at a steady rate which gave me about a 1/4" fillet weld. Weld penetration was good as in the middle of the left hand upright i actually burnt thru.
Settings

It may not look like much to some of you but it gives me a little more knowledge on the settings with the PowerTig Micro 185 for this type of application.
