I've been asked to help remove a seized/broken bolt fron brother-in-law's motorbike. Other than disconnecting the battery, is there anything else that should be done to protect the bike's electronics? I'll be using my inverter TIG.
1. Only safe way is to remove any electronic unit which has a capacitor in it.
2. Do not use HF with a TIG - lift or scratch start only.
3. Lots of debate in the trade - to leaving the battery on - to absorb some of the stray voltages over 14.4v (better than taking the battery leads off?). Vehicles have moved on a long way from rectifiers for charging circuits.
Personally I leave the battery on - and make sure the welding earth clamp is very near to where I am welding - I never use HF TIG or pulse MIG - I try to avoid welders with very high open circuits on cars - (hot start and dig also raises the voltages).
I have been a car mechanic for 35years and never fried any thing welding.
i have welded a car with the battery left in because the owner didnt want to loose the radio code.The teacher at the welding course I went on said that it's best to remove some ECU's/modules that are close to any area to be welded, in the past he had 'fried' such sensitive modules that maybe mounted/hidden under the rear seat of a car for example.
Which motorcycle is it? Some have ABS, traction control etc so you may find 'sensitive' electronics/modules on it.
Hf can be relevant.Irrelevant
If you view the arc, the plasma, as a piece of wire, then you have very powerful magnetic pulses being produced, as well as radiated RF energy. Guaranteed to ****** up sensitive electronic equipment.
As usual, a little knowledge is a dangerous thing! Just like my nan used to blame the bad weather on space rocket launches!
Yes, RF can be induced and rectified into small Voltages. It is the way that "wireless" charging is done. However, to induce any worthwhile amount of energy requires careful resonance design. The use of a welder, HF or not near other electronics will not cause any damage, but the myth continues to sell lots of snake oil, so it's "an ill wind".
How so, please explain the physics?
In the case of that plasma cutter, two students phones got fried when they walked towards/past that machine whilst in use.
That were why the school/teacher were issuing the advice now.
I can't,...I'm only saying what the teacher said.
