Hello,
Are there any good places to look for starting point settings for the common C&G test pieces? I'm slowly making my way through the test pieces and have two left, the vertical open root butt weld and a flat pipe.
I spent most of my last session trying to get the up hill single pass nailed on the 3mm thickness. As I'm adjusting the voltage and wire speeds I keep bouncing between too hot (melting a big hole) and looking good but not enough penetration on the rear. This evening I'll double check my angles with the tutor. The weld seems most controllable around 17/18V and wire speed set to get the sound nice. My path is the uphill christmas tree shape! Start on one side, diagonally up towards the centre of the root, then diagonally down to the opposing side of the start, then slightly more quickly straight across the centre to just above the start point and repeat.
I've found a few welding guides on you tube but most seem to be centred on much thicker metal and multiple passes. I was hoping that with the test pieces being so common there might be a guide kicking around!
