On Mon, 11 Apr 2016 17:46:40 -0700 (PDT), Is there a
heavier duty tip for the 140/100 watt gun ?

The standard soldering tip is the 7135 and variations.

Heavy duty (premium) soldering tip is 8125 and variations.

Make sure you don't get a tip made for the D550 or D650.

Or, if you're a cheap tightwad penny pincher, roll your own:

Other than for cutting plastic rope, I don't see the soldering gun to
be very useful these daze. I would not use a gun to repair any manner
of electronics on a PCB. May I suggest you invest in a soldering iron
instead?

opinions ?

Find a cheap replacement tip and sell it and the gun. Buy a soldering
iron and some desoldering tools. More free advice after you disclose
what you're trying to solder/unsolder/destroy.



There are plenty of times that I grab my 50 year old Weller gun. Just can
not beat it when I want to solder a couple of antenna wires and don't want
to wait on my 100 watt iron to heat and cool down. Those puney PC board
irons will not hold enough heat to solder a pl259 coax connector. I have
used one to solder to a PC board,but the irons are usually beter.

I guess that I did remember correctly that there were some tips that were
sort of flat on the ends instead of having that bump on the end where you
soldered.

The older ones that the ends are bent to an L shape and go through the nuts
are the best. The newer ones with the screws that go in the sides are crap.
One of my larger guns is that way. Works ok of you take the tip out and
clean the connections, but most of the time it will work loose and not heat
as well. I ran some tests on the current "wattage" used by the guns and
found that it was almost half when the connections were bad.



Agreed, the Weller gun can help in an area where you need to apply a lot
of heat, yet you don't want an open flame - like soldering ground braids
together deep inside a pinball game! Otherwise the gun sits in the tool
chest like many other tools we use once in a while...

Jeff, your solder furnace looks nice, but a gun is a lot more portable.

A solder gun is just another tool that can be used correctly or incorrectly.
