Re: welder question??
Poor ground?
Amperage set too low? Moisture in the electrode flux? |

Re: welder question??
70 amps is a very low output welder, I'm assuming you've got a stick welder (SMAW), probably an AC only version?? Without knowing more details, it will be difficult to help.
If my assumptions are correct, than a 6011 type rod would work best for you...easy to weld with, fairly forgiving, will handle a bit of rust or contamination, readily available (Ace, Home Depot, Lowe's). Try the smaller sizes, 3/32 or perhaps 5/64, these will be easier to strike and maintain an arc with. If my assumptions are incorrect and you have a wire welder (GMAW/FCAW), then we would definately need more details...wire size, type, self-shielded or gas shielded...

Re: welder question??
What side of rods are you using? I use about 125 amps or so when I use 1/8 inch rods. You are going to have to use small rods to use one of that low amperage. Also most new weldors put the rod straight onto the metal and do not pull it off in time (to maintain an arc) and it can stick then. I am guessing your heat (amps) is too low though for the rods you are using. (I am talking about DC welders btw, as I never use AC)

Re: welder question??
What kind of material are you trying to weld?

Re: welder question??
Turn the amperage all the way up and strike the electrode like you're striking a match, try to hold the electrode an 1/8 of an inch above the material and maintain that gap as the electrode is consumed.
You don't seem willing to offer much information and our ability to assist is limited by this.

Re: welder question??
Stick with the 1/16" electrodes...this isn't a very good welder and you will struggle with it doing much for you. A couple car batteries in series would do better...for $80 bucks, it's a case of you get what you pay for.
Reading the reviews, it seems that those willing to give an opinion are struggling like you are. Good luck.

Re: welder question??
RockTonka is right. I am in the welding supply business and I regret to tell you that you will have a hard time welding with anything other than 3/32" electrode as 1/16" is hard to come by. 20% duty cycle is rather low. I would suggest a 6013 rod as it is a much smoother bead and easier to run. Good luck.

Re: welder question??
E6011, E1012 and E6010 require you to manipulate the electrode. Also depending on the position you are trying to weld, the next to last number on the electrode dictates what positions it can be used for (1 is for all positions, 2 is flat and horizontal and 3 is for flat only). I personally like 3/32” E6010 for my “root” passes the move up to E7018 that stuff lays in real nice. I also agree if moisture got to the electrode it will not run for nothing. Take one of the electrodes and bend it. If the flux breaks off its good but if it bends with the electrode moisture has got to it and it’s no good. With all that said try turning it up until it does not stick. You will have to find the correct amps so it runs and does not burn through your metal. There are a lot more to look for, but without getting into a welding lesson try that first.
