Good advice nothing to add. If your wanting a stick welder check your local craigslist or yard sales. Stick welders have good prices since most are using the migs now. I bought a Lincoln over 25 years ago for $75. Still using it.

 6013 welding rod is what my welding instructor called farmers rod, I retired with welding certification for high pressure steam tube up to 6" diameter and 6013 was the worst thing I ever welded with. If you hold the rod square to the base material or travel to slow the slag/flux will run in front of the weld puddle and get in the way. This will prevent penetration into the base metal. If you lean the rod in the direction of travel it will tend to push the weld puddle and the slag away from the direction of travel so it is harder for the slag to get ahead of the weld and cause problems. With 6013 it is hard to tell while you are welding if you are looking at molten metal or molten slag. 6011 was the only AC rod that was rated as X ray quality welds. I assume that the newer AC 7018 rod is rated for X ray welds but I don't know. the first 2 numbers in the rod number are the tensile strength. I don't think 70 amps AC is enough to burn 3/32 AC 7018 and I don't know if smaller is available. 3/32 6011 would be working it hard. What size 6013 are you using. Don

Also remember when you are looking for a welder, Buzz box welders were deigned for people who couldn't afford a real one. Don

I don't agree and I have been welding for 50 years with mig, tig and shielded arc. No matter how fat your wallet is there is still a place for the buzz box in this world. A Miller Thunderbolt AC DC welder is not a bad machine for home and farm. Lincolns Tombstone welder has probably out sold any other welder on the market and many projects have been completed with them.  

Not trying to start something here but there are times when the Buss Box just makes sense.

I just did some welding 1/8 angle to 3/16 square tube using 1/8" 6011 at 110 amps with a HF stick welder (I think it's probably the same you have but I run it on 230V). I'm pretty happy with the result but I had to move very slow to get any penetration. It's also tough to get an arc started - I preheat the rod with a MAP torch.

I can't imagine getting a weld onto heavy plate at 70 amps.

Of course at 110 amps the HF welder only has a 6% duty cycle. That's a problem if there is a lot to do.

If I may, you can weld thicker metals with lower amperages, but you need to have it beveled and do lots of passes. We do this all the time to prevent blistering from heat on NiCU when welding schedule 80. For general steel, I run 3/32 usually at 90 for 7018 and about 70 for 6011. I think you can go as low as 80 on 3/32 7018. Anyways, like stated above, also not a fan of 6013, 6011 is a much better substitute. Oh, make sure to look for the puddle. Most people who booger bead are usually going to fast for the puddle, mainly because they are scared of flying sparks. Oh, lastly, my friend uses lower amperages than me, but he moves slower. Same effect really. There are lots of variables.

Just go grab a 3/32 pack of 6010/6011 and give that a try.
