Hot Tips
Tip:
NEVER heat the rod – only the work piece.
Tip:
When soldering Stainless Steel or Cast Iron, special care must be taken not to overheat the flux. Start heating the work piece away from the fluxed area until the flux turns to a white powder – only then move the flame towards the fluxed area to obtain the wet and light brown stage – ready to solder.
Tip:
Remember – the solder will effectively run to the surface treated with flux and heat applied.
Tip:
Soldering Anodized Aluminium will require removal of the anodizing.
Tip:
Repairing Radiators, Intercoolers and Evaporators, the porribility that thin oil penetrated the work piece must be kept in mind and must be removed, before attempting repair.
Tip:
Fixing holes bigger than 6mm will require a patch.
Tip:
Repairing holes 5mm and smaller on Copper pipe without patch:
Ensure to apply a minimum of liquid flux. This will prevent the flux and solder to enter the pipe and cause blockage.
Tip:
When joining dissimilar metals , it is best to prepare work pieces, with flux or by the tinning process, before joining.
Tip:
Keep the work piece away from draughts / moving air while soldering.
Tip:
Apply slight heat to the surrounding surface of the area to be soldered.
Tip:
Observe when thick metal is joined to a thin work piece:
heat the thicker work piece first.
Tip:
NEVER apply the flame to the Aluminium flux.
Tip:
Always observe the colour of the Techniloy solder:
a bright silver colour indicates the correct temperature – 210 degrees celcius – working temperature.
Tip:
Before commencing repair on a large work piece, it can be preheated to 180 degrees celcius in an oven.
This will ensure effective heating to working temperature of 210 degrees celcius.
