I've got one of the cheap weller 25 watt irons, and after very little use, i seem to be MELTING through the tips! Is this odd? Metal is just disintigrating.
I'm not concerned about the iron, i've got a hakko 936 coming in the mail. What bothers me is that i may be doing something wrong to make this happen.

Any suggestions on improving my soldering technique? Is there a particular brand of dumpster that works better for chucking this thing into?

My iron runs red-hot, and it don't melt.

You youngsters are just spoiled by new technology. What you probably didn't learn at the old tech's knee is:

Copper WILL oxidize and "go away". On a plain copper tip, the routine is: clean it, warm it, get solder ALL over the tip as soon as possible. Never leave the iron hot without frequently wiping on a damp sponge (not the good kitchen sponge; you can use a dampened rag) and re-tinning. And even then, every week or so you have to get out the file, re-shape the tip, and re-tin.

Ain't nothing wrong with that. ALL the "classic gear" was assembled with these irons. I worked many years this way. I actually PREFER plain copper tips. They hold solder and my technique developed around a very wet iron.

But then came the new-fangled iron-coated tips. I put one on my second best iron. It won't hold solder: just beads-up. I swore that when it burned-up, I would go back to plain copper.

About a decade later I realized that I could solder with a dry iron, and the iron was ALWAYS ready to go, no down-time to re-file. Even if I left the iron on all night (this would mean a major re-filing chore with copper). So I put iron-coated tips on my other irons.

I thought even cheap Wellers came with iron-plated tips these days. I recall paying $3, when copper was 3/$1, but in production work the reduction in downtime pays for itself in a month. So I didn't think anybody bothered to make brand-name plain-copper any more. I wuz wrong?

I got one as well - I am have been soldering now for 6 months - and I upgraded to this one..
I tin using those tin cleaners and wipe on a sponge and get no problems at all
I found my soldering technique got better overnight when I switched from 18swg solder to 22swg solder
I didn;t relaise I was using the "thick" stuff and couldn;t understand how anybody could solder the 0.1inch Molex connectors and IC pins with using 18swg solder..
So a lot of practice and using solder wick to get rid of my mistakes (I find a solering pump is crap) I finally managed to get my soldering technique good enough to solder those little buggers
Then I reread one of my newbie books and realised I had been using the thick solder and not the skinny stuff
So I bought a roll of skinny stuff and now it's bloody simple...
 
Thanks for the rsoponses guys,
I must be improving, that's the first message from PRR i've fully understood!
:green:
