[AT] Welding Advice

[charlie hill]

Mike remember that what you are trying to do is essentially melt the two 
pieces of steel together
the wire or the rod is filler but the metal being welded has to momentarily 
melt for it all to flow
together.    You have to stay down in the puddle with the wire or rod.  If 
the red spot is large
you are probably pulling out of the puddle too far.

Well as we get older...  OH you meant the welder :-)


What are you welding and what do you have the machine set at?
That machine should be able to handle 3/16" clean steel without an issue.

Polarity correct? If it was set up as a gas unit and you are using it
with flux core the polarity has to be changed. If it's backwards it will
lay a pretty bead on top but with no penetration.

Normally flux core runs hotter than the same wire as a solid.
