that is a really nice transformer

Great little video 😎 fixed 2ph input is interesting i haven't seen that before but i dare bet it's pretty common in counties with 16A 3ph domestic supplies? ..Those old line frequency welders are strong, ive got an old oil filled oxford welder and that thing is bulletproof 100% duty cycle... There was nothing wrong with your welding attempt mate, it was exactly what would be expected from anyone picking up an AC stick welder for the first time, FYI the new style cheap IGBT 2 switch forward inverters with DC output are pretty good for the money and a lot easier for a beginner to weld with. Also you need to dry your rods, Take a blow torch and gently heat the rods to dry out the flux before you start to weld, you can see the shade change as you drive off the moisture, if I've got a lot of welding to do i put the rods in the oven for half an hour, professional welders have heated electrode storage boxes called "welding quiver" basically a mini oven.. keep up the good work..

Farms will almost always have a 3 phase 63A service. The bigger the farm, more juice is available! I never knew about the rods in oven, explains a lot about these rods I found on a scrap yard and just kept in a cold garage :)

@@KaizerPowerElectronicsDk oh yeah of course on farms and commercial buildings, it's the same too, my friends pub has 100A 415V 3ph.. I was going on the assumption that the designer intended it to be able to be used on a 16A 3phase domestic supply for maximum versatility? The oxford welder has taps on the primary, it can run from a 13A 240V supply but also has taps for 380V and 415V, I sometimes use it as an autotransformer, it makes a great adjustable ballast too, I short the output and put the primary in series with the transformer or whatever I want to ballast and use the built in series tapped inductor of the welder to adjust the current.. it looked like yours used different primary taps to adjust welding current? I've seen that before in my cheap "CLARKE" MIG welder

These were also made under license in Croatia at the Uljanik Shipyard. 7018 rods are hygroscopic and must be kept in an oven. 6013 and 7014 are the most versatile.

Cool that it was made on license, I found a picture. Exact same unit and even says "Lic. ESAB" on the front. I found those rods at the scrap yard as well, so no wonder it sucked (I will let that be the excuse for my absolute failure ;) )

Your smoke-detector needs a new battery ;-) Older equipment is made to survive and last a very long time, as this video shows. Thanks!

[@KaizerPowerElectronicsDk]

I got networked smoke detectors, I change all batteries when one of them start beeping. When I postpone it a bit, over half starts beeping within a week. Quite incredible that they drain them that even.

I've seen people clean the metal first to get better results, not sure if that is as critical with sticks because of the flux though?

[@KaizerPowerElectronicsDk]

I did about everything wrong :O

[@kuglepen64]

Du svejser præcis som jeg gør 😂

Som en ørn! Først slår vi ned, så kæmper vi lidt og flygter så igen ;)
