Title: Resistance Soldering
Post by: colin on November 05, 2012, 08:42:27 pm
Whilst i imagine this is not probally used much in the model boat field, it seems to be mainly in the model train area that it is used. I would appreciate any thoughts etc into its suitability for fine soldering due to the heat being more localised. Price of units seem to vary from £459.00 pounds down to £99.00 for a UK manufactured one. Whilst £99 seems expensive a good temp controlled iron will cost possibly half the amour. All opinions please both good and bad and any other UK site / supplier would be welcome. The UK supplier i have found is Frost's in Rochdale others being in the states Microtronics.

I have one of the smaller resistance soldering tools, from Micro Mark.  I like it better than the old fashioned iron.  I can clamp 2 wires together with the tool before turning on the heat, and then get it hot and add solder quick and easy.  I do have to sand or file the tips frequently, to eliminate crud building up on them.

Ron Perrott has been using this sort of kit for soldering up the photoetched pieces on a Type IX u-boat he's building. He was in high praise of the equipment. Said it was expensive but worth it.

There are articles on building your own system. Might be a little cruder than the commercial units, but the cost would be about a fifth of a the cheapest system you quoted.

Its very well respected in the O gauge kit building fraternity (etched brass is a staple material of loco kits)
London road models does one for 175.00

I see that the guide to building your own was written by Vance Bass - he runs the pop-pop pages. Good man.

Lash151, here is the resistance soldering device I have.  There is an explanation of how it works.

Hi, Have you tried connecting the battery leads to the opposite sides of the joint you want to solder. Localised heat, very controllable, Nemesis

Thanks to all for the information The London Road models is the one that stands out at the moment has anyone got a contact number for them cannot find on site, Micro mark units certainly look the part but i would be the one that ends up paying all the tax,s etc.

Taken from the website:-
 Regrettably we do not have the facility to accept telephone or email orders and payment at present. Previous experience has shown that some telephone and email enquiries can be surprisingly trivial but very time consuming. Time spent dealing with these inevitably prevents kits getting packed and despatched, materials ordered, etc.

looks like you will have to put pen to paper :(
I'll see if I can extract a telephone number from someone I know who has regular dealings with them
