hi bborastero

thanks for the pic.indeed thats alot of soldering.

My solder tip of the day, if you have a 3d printer, print this:

Most useful thing I printed in the past 5 years

Also, use flux.

hi vertigo

i have a metal with magnefying glas and light too. the flux is a good tip.

I really like the looks of that 3d printed wire holder. I've always struggled with getting the wires to hold steady in the proper position. I've tried many tools to assist.

Liquid flux really makes the difference. It cleans the wire when heated and the solder flows nicely and is sucked into the joint. Probably any brand would do but this is the stuff I use. I really like it:

thanks dave

i put the link in my fav.i use mostly tape to keep the wire inplace.lol

I have a similar set of metal alligator clamps, but I find they are flimsy, will move and will move the wire when they clamp them. I almost always use my 3d printed helper instead when soldering wires, as the large grippers make it dead easy to align them. Admittedly though, your metal helper clamp thingies do look better designed than mine with a straight rod so you can move them in/out without changing the orientation. Mine looks like this

whenever I need to move the clamps closer, it twists the wires.

Anyway, whatever does the job
