Ideally you shouldn't use extension cords with welders But I have done it on countless occasions and all I have had to do is crank the amps up a bit
My 15amp welder said in the user manual not to use extension cords. I need one tho!
Is 20m 15amp 3 core 1.5mm2 thick enough to account for voltage drop or should I be looking for some 5 core and use 2 wires for active & 2 for neutral? I need prob about 15m of extension cord in total. I don't mind putting in a 20amp point if needed. As my existing 15amp point is near the metre box so it’d be easy to add a 20amp if needed.

A friend suggested 4mm flex but we weren’t sure if the plugs would fit or I needed bigger plugs

Just get yourself a standard 15m 15a extension cord and don't try to overthink this

We run extension leads all the time as there is never an outlet where you need it onsite. Sometimes trips, most of the time we don’t trip.
What rods to you need to burn?
I recently had to do a heap of welding on my garden edging at home, ran 30m ext. lead burning 2.5mm rods with out issue.
Over 20 meters in 1.5mm is fine - simple voltage drop calculator says just over 4%, and that’s assuming you have the welder cranked up and drawing 15 amps.

I have a 135amp mig/arc. I need to weld brackets onto my 120mm retaining wall posts so I can attach my 3m x 90mm carport posts. Building a carport in the easement that’s having 1 side attached to my existing concrete retaining wall. I’m going to buy the mig torch/gas/gauges so this job will be my 1st mig welding job.
I’ve run extension cords for my old arc without s problem

You can buy 15 Amp 2.5mm extension cords.
So a 2-4% voltage drop is ok?

Yep, no problems at all.
