hf start causes havoc with my mp3 player if the whip is close to or touching any part of the player or cord.

My buddy was welding his alum prop, HF continuous AC. I went to the basement and heard the sprinkler system water hammering. The HF was repeatedly kicking the solenoids, 40 feet away.
I unplug the sprinkler clock now.

High frequency. Since welding isn't lightning, the arc won't start without scratching the surface. This is ok on stick welding and MIG; but if you scratch your tungsten to start the arc with TIG, you might contaminate either the weld or the tungsten you're welding with. This isn't acceptable, TIG is super clean and we want to keep it that way.

This is where HF comes in. Instead of scratching the surface, we just hit the pedal (throttle control) with the torch tip close to the weld (1/8" or so). Now the arc will jump that space riding the HF current and ZAP we have an arc without touching the surface.

OK, and even though this HF signal will switch the sprinkler system on 40 feet away or wack out an MP3 player its still safe for my for my motosickle electrics with the battery and CDI removed?

Yes (if you don't put the ground clamp somewhere stupid)

The welding didn't damage the electronics that was affected.
Your bike electronics are almost surely better hardened than the sprinkler controllers or MP3 players because a normally working bike is not a good RF environment. There are spark plugs firing many times a second which are a significant EMI source and vehicle electronics in general are engineered better than sprinkler controllers.

Sounds like your guy knows where to put the work clamp to provide a low impedance circuit path.

Yes, He did say he would attatch the ground right at the clamp holding the additional tab. .

It is used in AC because the arc turns off 60 times per second as the current reverses from positive to negative and back. The high frequency helps keep the arc on and helps establish it. It is possible to TIG weld DC- without high frequency by scratch starting the tungsten to the work piece.

Yes it will mess with electronics but as stated if you disconnect the battery and set your ground close to were your welding you should be fine.

High frequency is just like static electricity with high voltage and low amperage. It will shock you but wont kill you. Just keep your body out of the welding loop.

I have no clue how to weld, i bought an arc welder 10 years ago i think it is a 70 0r 80 amp elder and i have never even turned it on. In fact its still in the box wrapped in plastic.
Having said that Im looking at my FZ6 and thinking i would really like to have some sideracks so i could mount some hardbags. I miss them since i sold my Ulysses and i only have a tail bag to pack my junk in everyday.
Where the hell do i start? I know nothing about welding.

To start: What kind of machine is it? A stick welder or MIG welder?

Whatever the brand, if you unwrap it there may be some sample welding supplies in there to start on, but probably best to unwrap it first.

I think its a simple stick welder, it has some rods with it and some handheld eye covers. Im gonna break it out this weekend and take a look because its been a while. Hope it doesnt throw all the breakers!

Have fun and let us know how it goes.

If you are close to Ocala, try and contact Phillip Kunts on here. I can't speak for him, but he has skills and may be willing to share some of the basics. Pretty good guy, and good dirt rider as well as being a weldor/fabricator.

I was like that, then i just thought to hell with it and read up on the basic idea, watched a few videos on youtube to get a bitof a "practical" observation going without having an instructor and off i went.

I'm still shithouse at doing stick, and need to work higher amps to really get it working, but have fallen in love with using my gasless MIG, that thing is surprisingly awesome to use, I love the feeling of accomplishment i get after i do a good job putting components together. Aside from buying the welder in the first place, that auto-darkening helmet purchase was the best thing i've done in my garage.

Oh and throw away the handheld faceshield, that's no good anywhere but in a chinese sweat shop. Get either a full mask with a flipdown visor, or (preferably) get a solar powered auto-helmet. That way you can tune the darkness levels to the task at hand and you aren't stuck with a single filtering strength that may be too dark or not dark enough for what you are trying to do. And you can line up the weld and then just go go go instead of lining up, holding still, flipping the visor with one hand and hoping it's still in the same spot you left it.
