Hi,

I have one of the older K40 machines without a amp meter originally installed, so planing to install one.

anyone else installed a amp meter and have some good tips when installing.

I am worried about the High voltage...

Even though i know how to connect it, i had to read it - twice. Good information and detailed explanation, love it :)

Hope this group can help me with a hard question!

How much external pressure can a fire extinguisher withstand before it implodes? Guessing 2mm steel, diameter around 20cm and about 50cm long.

Is there a equation for this?! Thanks

+Dag Elias Sørdal Look up 'Euler buckling' it addresses this problem, although spheres are a, ah, 'special' case.

Here's a paper:

I can see what caps it has on the board. There is one solid state cap that looks to be maybe 47 uF? I like a bit more capacitance myself. Lacking any optical isolation on the control lines I cannot even imagine how the board works. They must employ a different scheme to keep noise from running up those paths. Those boards are built down to a cost so they are pretty minimal.

How did you fry your regulators? You can add reverse biased protection diodes to those. I always do. The 1N4004s in this schematic are protection diodes around a regulator. They make any surge to go back into the power supply and bypass the regulator itself http://i.imgur.com/K1tL4or.png You can also see my optical isolation scheme in that schematic too. It is fiendishly clever if I do say so myself. There's a double inversion that leaves it positive logic. The Schmitt invertor squares the wave up out of the optocoupler too.

Good one!
 
I think the problem's in the source.

Glad to finally change out my old soldering station for a new Weller! Going to be a blast soldering now :)

I am still using standard 60/40 too, this was certainly not the case as the boards I repair are pretty old and do not use lead free solder.

I am just sharing my experience here, which has led into a strong opinion. Everybody deserves to be proud of his tools. Especially when paid a lot of money on them. A good tech can do miracles even with a steel bar heated in the stove.
