hi Stevexr, yes the lead will get very hot, now my son has the welder and he is exactly the same as how I learned, instinct and very curious.
I remember when I was Power of Attorney for an elderly chap his house had just had termite treatment, but all the floorboards had to be replaced so I tended it out to builders, as I was due for a hip replacement, so my son said he will do it, no experience at all, I used to love doing this myself, a challenge, and he did a 10/10 job and so it continues. Geoff.
