I am just getting started with MIG welding and have recently reached a point of understanding the mechanics. I have what is likely a very noob question regarding heat/speed setup when welding material which has mixed thicknesses.
As an example, if I were looking to weld axle perches to an axle tube in which the perch is 0.1875 and the axle tube is 0.25 would you set the MIG up for the thicker material and risk burning through the thinner material or is a heat range set up for the thinner material going to provide the necessary penetration for the thicker material?
X2. Set up for thicker and make your stroke a bit quicker over the thinner piece. I practiced by getting some scrap metal of different thicknesses and used different joint types between the two (lap, butt, T, ect)
Thanks again for the feedback. I am certainly no where near ready to put my life at risk with my welding skills (or lack of), the perch was the first thing that came to mind as to when this issue would crop up. Spent a little too much time practicing, without sleeves, already today and you can imagine what my weld burn looks like at the inside of my elbow..... Just another lesson
X whatever on washing from the thick stuff to the thin stuff.
I weld alot without sleeves, it's only for short times...most of the time. Get some spats if your gonna be welding in tennis shoes and short socks, them dang dingle berries will ruin a good pair of socks and burn something fierce too.
