Hi Phil

To be honest, the settings I chose for the test pieces were deliberately askew in order to produce test pieces best suited to ilustrate this particular thread .... Came out quite well considering that the 3 pieces done were the only ones I did

My welder is a 180 amp set with power settings of 1-8 & a wire speed range of 0-10

Sample A was using power setting 2 with a wire speed of 1.5 ish ( Blatantly too low a setting for the material thickness )

Sample B was using power setting of 3 & a wire speed of about 2 1/4 ( not that far off the mark for 1.6mm, I would say )

Sample C was using a power setting 4 & a wire speed of just over 2.5 .... A tad on the hot side for a down hand butt weld.

My personal preference is to weld a tad on the hot side, in my view, there is no worse sin than a cold MIG weld

I also hold the view that a properly set up weld job will do more to aid the war on distorton than trying to reduce the heat put into the job .... The propper weld procedure/sequence will help greatly in the fight against heat build up
