How To Weld Aluminum Uphill. Its just one way of welding aluminum butt joints. A 115-volt welder can handle aluminum up to an eighth of an inch thick 3 mm with adequate preheating and a 230-volt machine.
I set the machine to 140 amps and needed it to get a puddle but after about 5 seconds started tapering off with the foot pedal to compensate for heat building up in the aluminum weld joint. But it does work well. Press the foot pedal just enough slightly round the tip.

Each side will receive an equal amount of time and a small shelf will build up on either side of the weld. Vertical down welding is quite difficult at the best of times and many welding consumables and welding parameters will not allow downhill welding. Reasons for choosing stick over other types of welding.
