Hi all
I was researching welding for another project and was surprised by the following which I saved from a history of welding site,
The below patent is from 1886 so electric welding is older than you may think
Puts a few more years on to the repair, at least you are back to 19 th century
Regards
Ken

N. Benardos obtained Russian Patent (No. 11982) electric arc welding with carbon electrode called ""Elecktrogefest" or "Electrohephaestus". The methods of cutting and welding metals by the arc was termed "Electrohefest" in memory(sic) of Hephaestus, the ancient Greek god of Fire and Blacksmith work. (The Romans renamed Hephaestus to Vulcan and which is shown on the title page, giving instruction to the craftsmen forging metal.)
Benardos receives permission from the Russian Government to organize production in 1885 for "The production of this plant is based on welding and brazing by electricity and also producing devices for electrical illumination"
