Ok I’m trying to learn, I have a flux core lincolin. Let me know what I can do to make better welds? (puts flame retardant suit on) thanks.

 

what model? May want to slow your travel speed a bit...

 

did you clean(grind down) the metal before you welded?..where you at the right setting and was the pipe grounded good? it looks like you might have been going to fast.

 

yeah, looks like base metal was dirty or contaminated. and slow down travel speed, turn down wire speed or turn up the heat...
good luck

 

Turn down the wire speed and knock the slag off when you're done. You'll probably burn through that with higher heat.

 

yeah i cleaned it. well first i cut it then buffed it with a wire brush on my drill first.

"good ground" well i put the ground clamp on it the whole thing is bare metel so yes... i guess.

what kind. its the hd weld pack

it only has four settings for heat low1 low2 high1 high2
i made these passes with it set at low 2 wire speed at 5.5

when i turn the heat up i burn holes through it and if i slow the wire down, i get this popping thing going on. i'm not really sure what this is all about.

i'll give it a go with more heat less wire speed and slow my pass down.

thanks for the input!!!! and for not flaming too hard!!!

 

ok more heat slower wire = pop....slag...pop.....slag......pop


i ground down the “welds” if that’s what you want to call them, and this is what it looked like under all the slag.




i could see a couple spots that need more filler. but this might be as good as it gets with the flux core welder. i'm gonna need some ear plugs for all the grinding i'm gonna have to do. i hope i can sell this bitch so i can get a better one.

 

if its making that popping noise your' probably going to fast. keep it real slow and steady. when i weld with a flux cored wire fed i weld by sound and movement. i only use my eyes to make sure im stickin the weld in the right spot. keep the sound constant and you'll know the arc

 

What size wire are you using?

also, that looks like aluminized pipe. you need to grind that **** off before you can weld properly on it.

 

Flux-core looks just as good as mig does once you brush off the spatter and chip off the flux.

 

are you sure your developing a puddle before you start to move? and are yotu pushing or dragging it?

 

i have that same welder ....lol, and the poping is prolly from you going to fast, not grounded right and or the metal wasn't cleaned before you started to weld.

 

alright i'm not giving up,

i turned the heat up all the way and slowed the feed down. when the wire gets close it goes "pop" and the wire is gone. by the time more wire comes out the puddle has cooled and it just repeats again.

wire is .35. should i get the .30 ****?

pulling.

i'll grind down all the way around the pipe before i start next time and grind where i'm going to ground as well.

THANKS for the input.

 

put it on high 1 and around 4-5...add wire until it stops "dripping" or pushing the piece. Also, don't worry about cleaning the pipe. Unless it is super dirty, it isnt going to matter. Slow your travel speed down(not the wire speed, the speed at which you are moving the gun)

 

you're going to have to mess with the heat. at any certain heat, trigger/arc with the feed dial maxed and slowy reduce feed till it goes from poping to smooth frying sound.

you need to start and don't even think about moving till you actually watch and see your puddle heat and form. once it's the desired size, slowly and steadily push or pull along (don't add motion, circles, or weaving till later). the key isn't to move too fast or get spastic with your hand.

try what i said to rid the pops. just try running one bead fast. then, try one slow. you'll see a big difference. once you get straight even beads, then try moons or circles. keep trying and post more pics.

 

I say turn the dam wire speed up high, and wait till a puddle starts and then slowly move... just practice..

I am the furthest thing from an expert possible, but is the tip close enough to the workpiece?

Will your lincon HD accept the MIG upgrade kit that many other wire-feed welders do?

for progress

**** no it wont. i wish i would have known better.

 

why does it burn through? i'm like a retarted monkey here. i hope at least i'm entertianing you all.

 

ok this time i put the heat on hi1 and turned the wire speed up till i got a nice sizzle sound while holding the trigger. i just went for a straight line (I can even make a straight line with a pencil, I think being an artist here would help, I got a c in art) I pulled the trigger and was patient enough to wait for a small puddle (think I need a better mask too) pulled it a little, and then got off the trigger to let it cool some so I didn’t punch a hole in it. As the glow started to fade I did the same thing over again. The inside looks kinda like the outside , you can’t see the cut like in the pics up top. But whats up with ********? What causes these? Here the pic. For fun I’m gonna take this pipe down to the local welding shop and tell them I start for 30 buck an hour.


its the one on the right

 

your weld in the orginal post look fine that's what your settings should be at flux core is always nasty. the main thing you need to work on is puddle control.

if you going to weld that thin of metal on high heat, try to hold your gun ,at an angle, in the direction your going to weld and make a puddle. almost like a tack but hold it long enough to melt the base metal. then move the wire edge of the tack and repeat. dont move to fast or you'll burn thru. wait until you cant see it glowing (thru your hood).

here is a crappy paint pic:

this bitch is gone!!!!!!!!!! what kind of welder so i get i have $600 to spend. only plan to do exhuast and charge pipes.

 

it just takes practice. i started using a lil mig for doing my charge pipes and dp. after a lot of ugly birdshits im finally starting to get a little better with it. making single passes on the welds makes it much faster haha. here's one i did on my exhaust. i still suck at welding gaps as you can see the weld to the right. but when i get the pipes nice and flush its easy

 

still doesnt look like you are really starting a puddle

 

If you just got the welder, I would suggest learning on something flat, rather than something round. Worry about travel speed and pattern first before worrying about changing your gun angle every 1/4 inch. It will be much easier. You are moving to fast, slow down, make a puddle, then move. Make sure that your lense is clean and of the correct shade so that you can actually see the puddle.
