Resistance Soldering and Locomotive Electronics

Hello Fellow Railroaders,

I have a question for those more electronic astute than I. Could repairing a broken solder joint using the resistance soldering method on an Accucraft locomotive cause damage the models electronics. The question really is, do I have to take the model apart before soldering on it with a resistance soldering tool?

You should not have to..
But.........

This will depend on what/where you are getting things hot.

You will need to know where any wires / electronics / circuit boards are, and what is behind where you are soldering anyway. - That way you won't inadvertently melt something.

But the electronics (or plain electrics) should be isolated enough that you should not damage anything.

Thank you Phil. Yup, I wondered if connecting the locomotive to a low voltage/high amperage soldering tool could somehow ruin sensitive electronics inside the model.

Hi John,

"Nothing is certain, but death and taxes.."
But not a lot of difference to having a bit of welding done on a car.. This doesn't affect the electronics, more likely to melt the carpets! :devil:

Just watch out for what is going to get hot in the vicinity.

I'm not sure about this, but to be safe, the ground ought to be as close as possible to the solder repair joint and opposite the electrode.

John,
I really think you are over-thinking this?

The electronics are isolated from the chassis. *

I would be much more worried about damage to the paintwork, or melting a servo lead adjacent to where you are repairing the loco.
You are passing current through the chassis / Super-structure.

*Unless the lighting uses a single-wire, and chassis return.

"....Over thinking this?" Yup, it's a result of making a number of stupid impetuous moves with disastrous results.

Thanks again Phil.
