hey guys i have recently borrowed a welder from my uncle to begin learning to weld.
It is a 70 amp 110 volt mig welder with no gas.
it is for me right now a learning experience and one of these days i will go ahead and purchase myself a newer/nicer unit.
But for now i have been practicing my welds and i have definately gotten better, but definately not good.
i probobly have about 3-4 hours of experience altogether and i really dont that that i am all that bad for only having 3-4 hours.
what i have been doing is cutting my factory y-pipe up wherever looks good with a sawzall and then welding the two pieces back together.
I first started and was unable to weld a bead whatsoever, however now i can sit there forever and just keep welding around the pipe.
The main problem that i am running into is:
ugly welds, what happens is i have little ***** forming all over and that is causing the weld to look ugly. is this my error? or is it due to the welder?
it seems that no matter what i do i end up forming little ***** everywhere.
Thanks
Louie

flux core welding, or welding without gas is pretty ugly. Thats typically what is done on farm equipment or field repairs.

Without gas shielding you need to run flux-core wire (FCW). FCW spatters a lot. The spatter looks like little *****.
The spatter can be gotten off with a file, chisel, or wire brush (electric is better).

you can make decent welds with flux core, but in it's nature it's not a very clean weld so it's even more important to make sure the material you are welding is clean to start with...wire wheel it, and make sure you get all the slag off when you are through with the weld.....

i will get some pics for you. it is FCW. also i am not necessarily talking about the spatter but actually where i am welding ends up being a little ball every now and then.
Before a project begins i will purchase a decent 125 0r so amp welder that accepts gas, for now however i am beginning to learn with this.

yeah, pics would help...
as i said in the same thread you posted in the "tool" forum, if your bead is "balling up" you pry aren't moving fast enough and your heat is pry not high enough....your wire feed may be too fast as well...there are a lot of variables in MIG welding(from machine settings to the gun angle and speed you move to the different shielding gasses/fluxes to what you are welding), it takes a lot of practice to realize which ones need tweaked to get the desired effect...
