    Very cool, nicely done. Are you experimenting with small beads or is that part of something else?

    My instructor kept telling me to scale it down... after some experimenting I welded that piece. I think he is trying to get us ready for stainless. My new machine will be here in a week or so and I can't wait to see how well it preforms against a dynasty 350. I know it's kinda unfair, but I have good hopes My Micro 185 had a really nice arc and I'm guessing the 250ex will be better. I'll be posting lots of shots of my welds from the 250ex

    Hey, no fair! I don't have a Micro 185! Plus you really should be welding aluminum and showing off the A/C function of that machine anyways! Take advantage of that as some of us don't have fancy A/C and D/C welders!

    I have to say that I've done some decent beads on my PA 160 STH, even though it's a bare bones unit. I have yet to weld a test bead though...everything lately has been project stuff with short beads.

    I look forward to seeing more shots of your welds, especially with your new 250ex.

    70 amps? How thick is the base metal?

    I was thinking of running some more blades this weekend, I like to play with them every couple weeks. Believe it or not, I find it a really good exercise to keep close control of the torch... yeah, you can practice on big stuff, but a bit of wiggle or varying arc length don't really show as easily as welding up .009 thick razor blades. I usually set the machine around 10A and pedal my way around.



    Bead is a bit tall, only had 1/16 filler on hand that day. Penetration is great, through and through. Bit of warping towards the end, I just set them on the table, no clamp or third hand (though I built some since then)

    It was on 14 gauge......074" so 70 amps was on the lower end. The razor blade thing is great...gotta try that soon. And yes the Micro 185 WAS a good machine but sold it to help fund my 250ex. That should keep me busy for awhile I'll give the razors a go in a week when my new machine gets here.

    Clean them well... the oil coating the blades infuriated me, couldn't feel it, couldn't see it till it made sparks and stink, but once I started rinsing in acetone, got much easier. I use 1/16 1.5% lanth sharpened 4+ length to thickness (more focus, less penetration) clean it with acetone too, clean your filler with acetone. I was using 1/16 309L on those, I'm going to use some.030 309L MIG wire I got in since then, next time.

    Got a nice thin one coming up this weekend or next, welding the ends of a rollpan into the rear bed of an S10. The body is like tinfoil on those, not going to be like the body work I used to do on pre 70's vehicles.

    That looks good and good advice from your instructor. I have practiced some thinner material and it is not as easy to keep a small weld looking good as with thicker material.

    Don't know if I'd call it micro welding, but here are some fillet welds about .060" wide to secure some #10-32 nuts in place, without rolling over the edges or causing distortion to the threads.

    That's 410 stainless. 1.25" OD x 0.028" wall. I used 0.035" 309L filler. This is a fun drill because it really makes any change in bead width or travel direction pop out. And it's good practice for purging.
