Ok so total newbie question. By no means am I a welder...pure hobby and just started. When I stickweld with 1/16 I get a good clean weld with good penetration (wheni say good I mean for me). When I use 3/16 it is a mess. High welds and just a nasty looking weld. Ill try to get some pictures loaded but any suggestions?

Hey,

Welcome to the show. The first thing to remember is that a 3/16 is a fair hunk of rod. Used for laying down some serious welds. Im not sure of the suggested amps but it would be fairly high. You will need to crank it up a long way from the setting for the 1/16 . Its possible your machine wont run them. Ps What type of rods are the, There will be an E___ Number written on the rod and box.

Answer to the first ? 1/8 :lol:

The second? AMPS!

Seriously you need to lay out all the parameters to get the best response. Machine, electrode type, material type, material thickness, joint type, position and settings.

Almost forgot joint prep :oops:

Hi and welcome. Since your new and your question shows it (nothing wrong with being new, we were all there at one time), I can pretty much guarantee that you probably don't have a machine that can run 3/16 electrodes. The 3/16" is F-I-V-E :o :o :o times the size of the 1/16" electrode. It's also two sizes larger than the standard 1/8" electrode.

What machine do you have and we can suggest electrode sizes for you. Pretty much any machine can burn 1/16", 5/64" and 3/32" electrodes (in that order).

Ok sorry for the delay. I am using a logevity 160sx ac/dc welder running off 110.

http://www.longevity-inc.com/productcat ... weld-160sx

6013 -1/16th @80 to 90 amps
6013 - 3/16th @95 to 120 amps

Evrything is prepped to a shine.

I was told by a local welding supply that 3/16ths is what I shoukd be using but much better welds with 1/16 (well i think i get better welds)

1/16th 6013 basic steel
1/16 6013
1/16 6013

Any suggestions on my welding would be awesome. I am just starting with this. Aside from welding a really messy table this is the second project I have worked on.

Thanks

3/32 would make sense. 3/16 is way too much rod for that machine

Two things. First as mentioned, 3/16 is way to big for your machine- are you sure they sold you the correct rod size? Second sounds like they meant to tell you 3/32, maybe you misunderstood or they gave you the wrong size themselves. The amperage you listed is correct for 3/32. However 6013 3/16" amp range, per Miller weld calculator, 150-230 amps.

Thanks for the replys. That does make sense then for what im doing the smaller rod should be fine. So there is not enough amperage to get the heavier rods to burn in.

Any suggestions on this weld then?

Too flat? Slow fast? Suggestions for a newbie.

Thanks for the help!

Pause a little longer on the start to get that slag to burn out. Other than that its looking pretty good.

I would get some 1/8 at 125 amps or 5/32 7018 at about 150amps, should do a good job on you metal.
6013, in your application, is crap.
