RE: [DML] Fuse box replacement SOLDERING GUN

["Pasquale Lombardi" <pasquale.nj@xxxxxxxxxxx>]

IF he is using a WELLER gun with nuts holding the tip into the gun in 2
places,

it MAY be that he needs to loosen and retighten the nuts 

as they may have a poor contact today, causing a poor contact in the heating
circuit.

I will check the type of solder I'm using, I know it's rosin core and it
says ideal for all electronics repairs. 

Those soldering stations look like the cat's meow, however this is the most
soldering I've done in my life and I doubt I will do this much again anytime
soon. I don't think I can justify buying one! I'll probably just keep on
with my gun but I'll be sure to follow Nick's advice and use minimal solder.
I think I'm doing a good job so far, it's just tedious but what did I
expect????
