Have a 120 volt 70 amp stick welder what gauge or stick type do i use
1/16th stick to 3/32nd.
3/32nd being the maximum. Don't use 3/32 for an extended period of time, or you can burn up that welder. (Even if it has a fan. If it doesn't have a fan built-in, I invite you to put a house box fan, close to the ventilation slots for the welder)
I would also recommend using 6011 rod. It's a mild steel rod, and is excellent to begin with. Usually used for filling, and medium strength situations. It does splatter, be aware of that.
Not trying to give you a tutorial on beginning welding, but would like to offer some tips:
1.Make sure the ground clamp has a good, clean surface it's clamped to. If not, it will be very hard to get the rod started, and also to keep it going. (Makes bad welds too)
2.Start with a B U T T weld. (Had to type it that way do to censorship of certain words)
That's laying two pieces of metal next to each other, and laying a bead in-between them. Easiest thing to start with. Go to corner welds next, (Two pieces together at a 90 degree angle), then try Uphill welds.
3.Shield flipped up on helmet, welder on. Lay the rod past the area you are going to start on. Past the metal edge. Lay the ->flux coating of the rod on the edge of the metal piece. The tip of the rod is past the metal edge by at least two inches.
This way you are lined up to begin the weld. Then flip your shield down, draw the rod back, until the tip of the rod touches the metal. Once the arc starts, lift the rod up a little to get the correct height, and keep that arc going.
4.Watch the PUDDLE, not the arc! You are watching the melted metal in front of the arc. You need to see how that puddle is doing, in order to compensate by bringing the rod closer, or further away.
5.Use a Zig-Zag pattern to begin with. Keep the Zig-Zag close to each other, until you are comfortable enough to make a longer pattern. Watch the penetration. Good penetration is the key, not a pretty weld.
6.Use the proper safety equipment. If the welding helmet lens has a tiny little scratch, you will burn your eyes. NO fun, believe me!
You won't know it until you wake up the next day with your eyes swelled shut!
Cover your arms, and use welding gloves. Welders give can give you a radiation burn, worse than a bad sunburn. NEVER just start welding a little with No welding helmet. Welding goggles are for the birds, or Acetylene welding!
Be safe, have fun welding!
