I have two WU81 Weller
Perhaps this fuse should be a "T" type or delayed acting (antisurge fuse) . If the fuse has been replaced by an "F" fast acting fuse then this could explain why they are blowing.

WES 51 LED not flash to indicate ready
the iron has a temp probe inside the pencil, most likley the problem. also these have problems with the powersupply but usually it won't heat if its a power supply problem. best guess would be the sensor in the pencil

Soldering iron troubleshooting
Bits: It's useful to have a small selection of manufacturer's bits (soldering iron tips) available with different diameters or shapes, which can be changed depending on the type of work in hand. You'll probably find that you become accustomed to, and work best with, a particular shape of tip. Often, tips are iron-coated to preserve their life, or they may be bright-plated instead. Copper tips are seldom seen these days.

Zx7-225 welding machine cannot lower welding amps with the manual control.
The correct current, or amperage, setting primarily depends on the diameter and type of electrode selected. For example, a 1/8-inch 6010 rod runs well from 75 to 125 amps, while a 5/32-inch 7018 rod welds at currents up to 220 amps. The side of the electrode box usually indicates operating ranges. Select an amperage based on the material thickness, welding position (about 15 percent less heat for overhead work compared to a flat weld) and observation of the finished weld. Most new welding machines have a permanent label that recommends amperage settings for a variety of electrodes and material thicknesses.

Change polarity on older mac mig welder
So, for gasless
MIG welding polarity (when using flux core wire), your
MIG welding polarity settings should be set to direct current electrode negative (or DCEN). With DCEN, the negative terminal inside your machine is hooked up to your electrode (your
MIG gun) while the positive terminal is hooked up to your ground.

What are 4 common welding processes?
There are four common welding processes utilized through out the work industry today. They are :
(Stick Welding or SMAW) Shield Metal Arc Welding
(Mig Welding or GMAW) Gas Metal Arc Welding
(Tig Welding or TMAW) Tungsten Metal Arc Welding
(FCAW) Flux Cored Arc Welding
There are many many welding processes, however these are the most common. The type I am going to discuss briefly today is SMAW. The most economical and cheapest way to learn if welding is for you or not is to start with stick welding. It has the least amount of variables that can go wrong for a beginner. It is not fast paced like mig or flux core, so you have time to watch the molten puddle to see what it is doing and make necessary adjustments to correct the size, shape, and contour of your weld bead. The hardest part for a beginner is to keep the electrode from sticking to the work piece. Thus is the reason it got the name of "stick welding". There are three common ways to strike an arc in SMAW. Tap Start, Scratch Start, and the last is to place the electrode upon your fingers like a pool cue, and shoot the rod like your playing pool.
