Did some more today but the 7018's just wouldn't light up!
Even put them in the oven to see if they were slightly damp and still wouldn't!……..They shouldn't be as they were left in the boiler room next to the boiler on a high shelf……….so taking them back to the shop tomorrow and gonna see if they were just a bad batch (I did pull a couple out the box and the flux was cracking)
Only difference between today and yesterday was the amperage setting, was using high volts yesterday and used low volts today so I could get higher amps
So 6013's had to do which was fine as there were no structural welds just the trim pieces on the side and a couple of caps, my stick welds are slowly getting prettier
This is a bit of an ugly one and it was stop start yesterday with the 7018 but theres no slag inclusions so its all good
So I covered this with a 6013………..you can see where the breaker tripped and I had to
reset it before carrying on with the caps
Again a little cap over the 7018's before grinding down nice and smooth, the slag chipped off easy enough (this is post chip/pre clean with wire brush so theres a few bits you can see knocking about)
Angled sides were tacked on
You can see again where the breaker tripped so after resetting I needed to re do the end of the weld after a quick grind

nothing wrong with the welding rod Doc. Just the person welding with them. Not set up right or experience is all. Just give it time
Looked at your pics are you using 7018 ac/dc rod or straight 7018 rod?
Remember you are using ac not dc for welding.
heat looks a little high and you are moving to fast slow down a bit. when you get to the end of your weld hold the puddle a bit and let the crater(stop) fill in

It is the person not the rod. take them back to the store and they will have a good laugh at your expense

I'll give them another go tomorrow on some scrap but they just didn't want to light up today may try it on high volts tomorrow and see if it makes difference
check you ground at the welder and clamp

nout wrong with earths, same as they were yesterday and earth was probably 6" away from the part I was welding as I was just sliding it up and down the box section as I was yesterday when they were running, it seemed like the metal was melting but the flux wasn't as the couple of times it sparked up and welded for a few seconds the metal had burnt up about 5mm inside the flux and just left a hollow tube
Ground at welder is a nice big copper lug with brass bolts and I tightened that up properly, cables are the original 1960 ones though so could probably do with being replaced but they're still welding fine with the 6013's

They're meant to be AC/DC ones SIFtrode 7018 Low Hydrogen Electrodes - Weldequip
So thats why I was wondering if they were a bad batch or if something was up dampness wise but I baked them as it says to on the welding forums to make sure theres definitely no moisture in teh flux

not neither. damp/wet flux you get prosity in your welds and flux will pop off when welding

Well the welds it was putting down yesterday weren't porous and today the flux definitely didn't seem damp, the one that was freshly baked at 250* for a good half hour didn't do anything
At a loss with these so will see if it was just an off day………if it turns out it doesn't work I'll just use 6013's for the rest, all the structural ones on the centre section are done now

If the circuit breaker is dropping out regularly then you've overloaded the circuit.
