Slow down,brace your hand and i think your heat may be a little too high.Go down i heat range and weld slower.Try welding two pieces together because that is what you will be doing.If you are welding two different thicknesses together weld more on the heavier piece . Best advice is slow down.

the heat settings are a b c and d wire speed goes 1-10. the settings im using are b for heat and 3 for wire speed. if i go any slower it burns wholes so should i turn the heat down one more notch to the coolest setting.

Re: few mig attemps
 

Usually there is a heat index for what your welding. It should give you a good idea of wire speed and heat range for different material and thickness. Mine is on the inside door of the spool feeder access.

i bought it used the sticket may be gone ill check.

Cut the pipe and weld the two pieces back together. Thin wall ---- like that is always a pain, but I like a high heat and low wire speed personally, then I just do a bunch of stacked tacks.

Re: few mig attemps
 

less heat and less travel speed.
you'll more than likely need to weld an inch, flip it 180* weld an inch, etc till its all done. That thin BS is harder to do without good equipment.

better pics and take your time :6

Really? When I butt-weld exhaust pipe I usually use a low heat setting, and medium wire speed. That way the extra wire "fills" the gap.

Re: few mig attemps
 

Yeah I tend to burn through with my welder on high but I only have a Hi/Lo no in between and Lo is weak as ----. I do turn it down if I have a gap though, like if the pieces don't butt right up to kind of give the metal more material to weld with.
