It helped a bit, but not as much as I might have liked, I think a skill upgrade will be required to make good use of them.Yes, try a higher voltage if you can.

I've spent my entire welding life on 6013's and never succeeded with vertical ups, must try to buy some 7018's but rare as rocking horse poo in French welding shops, aka, non existent.
Really must order some and try.
Yeah I've had similar experiences, wouldnt run at all on my transformer machine, they run beautiful on all 3 inverters I have though! hence me suggesting 7016 as I believe they're meant for ac and have similar characteristics to a 7018.Just as a quick note to be careful of 7018 and AC welders.
The Bohler AWS 7018 that we use all the time on DC welders, and also Fox EV50 does not run very well on AC welders. It would barely stay lit on both of our BOC oilcooled transformers. The packet says AC, DCEN and DCEP, but the datasheets say DCEP.
A lot of 7018s are DCEP only, not AC.
These same rods make a strange sucking sound when ran on DCEN so at least you know if your polarity is wrong
I am glad someone has brought this up, years ago I was using 7018's on an old Oxford machine and although it did the job, the arc would just break and the metal of the rod would burn right up many mm into the flux, had to break the flux off the rod and start again,Just as a quick note to be careful of 7018 and AC welders.

I would seriously consider if you can buying an inverter at the price of them now a days, even a cheap one would be a great investment and allow you to weld positional with ease.
I used to use an old oil cooled to weld pipe, they burn a 6011 well (used esab nu5 for the root) they are available at a lot of welding supply shops.I would doubt that an oil cooled oxford would run a 6011 rod & they're not easy to find in the UK either.
My recommendation would be a 7018 from any of the quality suppliers like oerlikon or bohler fox. Honestly, once you've got used to starting them you'll never use a 6013 again!

your oilcooled will have 50 and 80 v output terminals , get some filarc 56s in a vac pack set to 80v and crank the amps up you will keep the 6013 for stirring paint if you want big holes in thin metal and scars for life use 6010 / 6011 not a rod for a learner in overhead position unless of course your a yank

I would use a 6013. Burned thousands of them out of position. The Boss ones from BSS are cheap and good quality + they are easy to store/ no vac packs or rebaking generally Passed x-ray with them. Just my take
I have already learned that lesson with the 6011, it digs like an angry mole!your oilcooled will have 50 and 80 v output terminals , get some filarc 56s in a vac pack set to 80v and crank the amps up you will keep the 6013 for stirring paint if you want big holes in thin metal and scars for life use 6010 / 6011 not a rod for a learner in overhead position unless of course your a yank
I have a friend that does pipeline work, did allot of work down in Carrollton county ohio with the latest Marcellus shale boom. a few years back.however "surprisingly "a good experienced man with 6010 can still bury most welders in rod ends but you will have to pay him piece work to ever witness it
But for general purpose a 7016 would be my preference as 7018 is a filler rod, it produces more weld metal for welds such as a second pass in a Vee'd join.My recommendation would be a 7018 from any of the quality suppliers like oerlikon or bohler fox. Honestly, once you've got used to starting them you'll never use a 6013 again!
Cushion elbows with those kind of pressures at the well head would be the least of your worries. If a sand screen starts to fail down hole youll cut a choke in a few days!I have a friend that does pipeline work, did allot of work down in Carrollton county ohio with the latest Marcellus shale boom. a few years back.
He told me:
1. pipe from well to pipeline is 6", normal used to be 2"
2. Sch 160 double extra heavy pipe.
3. Cushion elbows because of the sand erosion.
4. 8010 root and all cover passes.
5. 100% X-rayed.
6. Pressures at well running 5k-7k psi.

Kestrel Marine also had a yard at Wester in Caithness, from memory they had a hanger at the airport in Wick too for some work, they installed huge lighting towers at the harbour which were just removed a few years ago.many moons ago when welders were recognised as highly skilled and paid accordingly the kestrel marine yard in dundee was mostly welded with Ac pots with 80 >100 v ocv the welders test for the start was a 6g heavy wall pipe 56s with ac , with the onset of tig roots dc was used more in the pipeshop and was a revelation for stick roots and so much easier , 88s became the go to rod for structural and low temp pipe i remember the methil yard had procedures to run88s on negative this tamed them and made them realy easy to use on the bottom of the pipe. if youve used 4mm 88s on shd 80 pipe youl no doubt have blown a few roots and hot passes , these rods have mental dig about them on + and need a skilled operator with a remote to humour them on the 7 to 9 o clock danger zone
the 88s gave very clean xrays as they were so vicious they killed 99pc of all known germs if used with the (domestos juice) high amps
When a well is drilled, the oil bearing zone cuttings and rock structure are analysed. Once the well is complete different casing types at the oil inlet end are used. Some are a gravel pack, so simplistically gravel packed around the tubing to allow oil and gas to flow, but hold back rock. Others if its likely to produce lots of sand would have sand screen, where the oil bearing end of the tubing is wrapped in fine very strong hard wearing wire, creating a filter to hold sand back but allow oil and gas to flow.I just wrote what he told me.
He did not mention any downhole screens.
