Extension Cables/Welding

[retroray]

Thanks everyone! My electrical knowledge ain't great so how do I work out the power I need to be running?

Am I right in thinking I need to up the amps to make up for the voltage loss?

I'm probably only going to be welding panels up to 0.8mm thick. My welder is a Clarke 90en so two settings on it and a max and min button

Or am I really not going to notice it much on metal this thin?

I wouldnt worry about it. Just weld and if you need more heat turn it up.

Agreed, don't get hung up on numbers and theory when welding, adjust to achieve good welds with good penetration. How you achieve it is less important.
