Default my shitty welding abilitys......tell me what to do different lol

allright so i went ahead and bought myself a POS harbor freight welder, its a 220v
http://www.harborfreight.com/c...=6271<--take a look at the beast!.......anyways the duty cycles are:
15% at 115 amps - 30v
27% at 75 amps - 17.7v
60% at 50 amps - 16.5v
100% at 30 amps - 15.2v

im guessing those are really shitty numbers?? well anyways ive only used it for like an hour altogether now.....im using 75/25 argon/co2 gas at like 25 lph or cfh lol.....using .030 carbon steel wire, on some 1/8 or maybe 3/16th's steel......tell me what i can do to get a better weld please lol!!!
most of the splatter is from when i was playing with the welder with flux core

turn the heat up a little bit and play with your wire speed to get rid of the spatter, play with your post purge settings if you have them to aleviate the craters at the ends of the puddles.

ok so ill turn up my heat

up or down on the wire speed?

how the hell do i do that with the post purging? just hold the trigger part way down and let gas come out??? only reason that is my guess is i hear the gas come out with partial trigger pressure, and both with full pressure....thanks!

generally if you turn up the heat you have to turn up the wire speed a little, but you may be able to turn the wire speed down and keep the same heat for a smoother puddle with less spatter.

yeah if your welder doesn't have the option, try keeping the trigger depressed slightly when you complete the pass.

those welds look pretty decent though just need some fine tuning in your settings, maybe practice the technique a little.

the splatter is 99% from when i was welding just outside of the picture the other day with flux core, it just got everywhere.......thanks for the tips, now what technique should i be using i just kinda do a bunch of circles like ooooooooo if you know what i mean, never really learned how to do it right

99 of 100 professional welders do NOT do circles. The only reason I've done circles would be if I was playing around with a "tee joint", laying it down like a trough and seeing how much metal I could put down in one pass.

If you're doing circles, then you're wasting time. If you need a wider puddle than just a constant drag or a forward/reverse motion, just do a little zig zag. This helps to widen the puddle without making it taller.

No,

I use a circular motion, or a variation of it almost every time I MIG any sort of T-joint, so do all the other people I know, that's how I was taugh at school, and thats how I've seen countless people do their qualifications.

So you're saying that a bunch of rookies do it?

In many cases, people are not taught the right or best way to do things at school. From my experiences, I have only seen 3 good welding instructors, one being myself....one was one that worked with me, and one was the guy that taught the pipe weldin school I went to.

Most teachers can't weld for ****... the students may think so at the time, but when the students can't weld for ****, they think the teacher is great.

I've had over 50 certifications, and didn't do circles on a single one.

no, I'm saying that rookies, teachers, and proffesionals who come in to test and renew their certs do it.

I've had plenty of great welders as instrutctors, they haven;t always been the best teachers, because where I went to school welding experience and not teaching expericence was what got you hired. It's like when I went to a regular university and I had professors who were exberts at their field, and did great research but had trouble conveying what they knew to their student.

Why are circles so bad? The miller tig book in front of me shows them for T's, I'm positive that any other books I check, like an AWS one, or a navy manual will also show it too.

Most instructors I have encountered couldn't weld well themselves, much less, convey it to the students. Figure, that most instructing positions pay pretty well compared to other jobs that aren't traveling types of jobs. Therefore, it's usually quite a catch of a job....and it goes to somebody's buddy or brother or something. Otherwise, it can often be a situation of a person picking a welding instructor, when they know nothing about welding or industry..and they just go with the resume that sounds the best.

Many books and such will tell you to do circles... it's the easiest to explain though, isn't it? It's the easiest to learn too, right? now try doing it welding in the vertical position, upwards. It's taught by many people that are simply not knowledgable enough or are too lazy to teach you a better way.

I appreciate your response.

Sorry if I come across as angry, I'm not trying to be confrontational here.

What technique would you use then? Do you ever whip? or does that fall into the same category? What's wrong with circles? penetration? from my experience just straight beads can tend to be overly convex, I guess it's it's harder to undercut though.

I've done plenty circles vertical up, although the preferred method I was taught is "christmas trees".

I've heard some nightmare stories about welding teacher, but I've been really lucky with mine. With two exceptions every welding instructor I've ever had has also worked as a full time welder while they were teaching me (I went to night school), the exceptions were both semi-retired from field with like 30+ years experience each.

I prefer a motion something like 1/4" forward, and 1/8" back, then repeat. You may find it better to even move forward about 1/8", pause, then repeat.

If you're using flux core wire, backward motion doesn't work well though, because then you're having to remelt the flux that has already solidified. With flux core, it tends to weld better with zig zags. or just dragging.

Same with me. Sometimes I sound pissed when it's just one of those little "peeve" issues....not so much an issue with any person. I'm not very pleased with the educational system overall, and definitely not when it comes to welding instruction. When the best welders often have to teach themselves, due to not having quality instruction available, it's a problem.

Try a zigzag to help spread the bead out wider, if that's what you want.
Many people think that slowing overall travel will improve penetration and that's rarely the case. If you think about it, when welding mig, you slow down and you're putting a thicker bead down...and you have to burn through the entire depth of that bead before you actually start to penetrate into the base material.
