Basic Electricity and welding machine technology

Here's a useful link I recently found for a training course on basic electricity and welding machine technology:

I'm very fond of the old Lincoln Electric Welding Handbooks. And how about those rivited boilers and steam turbines in the ole cruise liners and battle ships. I'll be checking your link.

I know less than nothing about welding, my brother is a Master welder, so I do wood 
Miller makes good stuff though, we used their heat exchangers to cool gradient amps, (modified versions of Crown DC300s(?) )
I still got a couple pump motors, one's currently a bench grinder.

I got lucky. I fell into this job a long time ago and was able to absorb most of what I know by hanging around and paying attention. Miller and Lincoln have always done a great job of providing us with training and phone support. We have also enjoyed those Lincoln handbooks, silverfox.
I got into amps because one day I compared a JCM800 schematic to an inverter based multi process welder and thought, if I can read this, I can definitely apply it to that.

I posted this link as a reference to anyone who might need things explained in a different way. For me, multiple sources of the same information has eased digestion.

I rarely work on equipment anymore because my position has changed and I miss it. But, I really don't want to spend half a day troubleshooting an "output issue" in this new, totally over-engineered equipment. Ain't nobody got time for that.

I'm just happy that some of the electrical principles were useful to me for this hobby. Once you hear/see/jump away from a rectifier fail whilst passing 400+ amps you gain an appreciation for anything that can be fused under 5 amps. Before I got into the JCM repair (2010'ish) I had been lured in by the "How To Service Your Own Tube Amp" book by Dave Hunter. I had to put 1+1 together to realized that I could hurt myself just as bad inside a chassis as I could by walking through the shop on any given day. I got hit by 460V once. One handed stupidity, and luck. I was one other hand away from being a blown fuse.

I have been bit MANY times over by welding, the absolute worst was me up to my armpits in a pipe rack, had stainless pipe running under both arms in fact I was hanging on by my armpits, TiG welding a weldolet onto a 2" line right in front of me, and I pulled off the torch and it just happened to arc to the wire I had been welding with in my left hand, OMG that one loosened the fillings in my teeth!  If I hadn't been so tightly lodged in the pipe rack I might have fallen out the bottom.  98F outside and near 100% humidity in a hot sticky steamy coastal North Carolina summer, up near the roof with no air moving, soaked down to my knees in sweat..  All the other times getting bit was nothing.

Speaking of 460, a buddy I used to work with got into an open panel on shipboard, and another friend seeing what happened picked up one of those big water fire extinguishers and threw it at him hard enough to knock him down, freeing him from the volts.  It saved his life but he went from having hair down to his waist to not having a single hair anywhere on his body, no eyebrows no ear hair nose hair beard moustache, nothing just smooth skin.

You are confirming what Jimbob says about you: your tube and geetar knowledge

Who is this Jimbob clown you're talking about?
I know not of whom you speak.
