    Do you know what model it is ? It should say on the front, side or a sticker on the rear.

    well thanks for those tips ill take my camera to school monday and take some pics of my welds and post them so you can tell me what im doing right or wrong. I did notice some spattering around the weld so am i using to much heat and also the rod seems to be burning down real fast i was running on 120 i think ill take a pic of the machine setting too cause im not sure how to figure out the dial on the machine, it has numbers for ac and dc and i dont knwo how to tell if the machine is in dc or ac mode.

    I did, thanks for correcting my mistake.

    Sometimes my typing gets ahead of my brain

    you probably need to slow down. they seem like a slow rod to me, but that could be as I'm doing vert up with them ??? in general though i seem to want to go too fast. the slag is not the bead so let it grow. you have to be able to tell the 2 apart. that and get your heat right.
    post us some pic's and maybe we can get you an idea as to what is the best way to go. a pic is worth a 1,000 guesses.

    If you are just starting, you may need more practice before you have a pretty weld. A lot depends on what amperage you are using with the size rod you are using. Make sure your metal is nice and clean if using a 7018 rod, wire wheel or grinder works nice for cleaning it up. If your weld bead is high you are running too cold, if it is low and your sides are undercut and a lot of splatter, you are running too hot. Using a 5/32 rod, start at 80 amps and adjust your amperage up from there, using 1/8 rod, start at 125 amps and adjust your amperage up from there. Do not rush with the rod, watch your puddle as you move, you should see a nice uniform look to it as you move your rod back.

    im currently learing smaw. using 7018 electrodes. What is the best way to get the nice ripple look that looks like dimes laid over each other. Im welding stringers right now on just flat plate. im holding the electrode at like a 45 degree angle is this to much angle, and im dragging it on the metal is this correct or do i need to hold it a little above the base metal.

    hey fellows

    well my first welding class went off without a hitch. But i did get burned right on the finger ignorance causes pain lol. But i started off stick welding today. Just welding stringers flat surface lines. My instructor said i was very good for my first time doing it, and he said he weas proud to see someone do so well the first time they ever picked up a stinger.

    i to have bought a few things from IOC but have not bought any welding machines or anything like that just safety gear But the prices are very reasonable, another good one is quimby corp, and weldfabulous.

    i got all my welding stuff from IOC. MIG, TIG, and plasma cutter came from them. as will my next purchase. great people to deal with befor and after the sale.
    i have heard runing the torch over the work at a lower amp befor welding it can help prep it also. might give that a try.
