Solder Blocks: Select your various block Solders in Easy Med Hard ( weight may vary) of the drop down menu. Silver content: Easy 65% Medium 70% Hard 75% Melting points: Easy 705 – 725ºC Medium 720 – 760ºC Hard 745 – 780ºC TIPS Make sure both sides fit perfectly (flush) & that the surface area is large enough. Remove the burr (that is filings and saw blade damage). Use some sandpaper. Keep solder edges absolutely clean fat & grease free. Make sure Flux & the Flux Brush are clean. Do not apply dirty flux to soldering area. Clean flux brush regularly. Leave a slight gap between solder edges for solder flow. Flux solder edges & place solder strategically. Use correct amount of solder. Set flame correctly & heat evenly. Distribute heat correctly (both sides of piece must reach flowing temperature of solder together). Never concentrate flame on the joint only – Solder will only flow properly when heat distribution is correct. Do not stretch solder further than it will or can go – it will cause overheating & destruction of the solder composition. If solder does not flow or stops flowing – STOP! Clean and start again. Be very careful NOT to leave acid residue in the seam. TECHNIQUES Preplacement: Small pieces of solder are placed at the joint seam prior to heating Heat is then applied until the solder flows to the joint Feeding: The fluxed joint is heated to temperature and tip of the solder wire is fed into the joint and should melt on contact We stock a large selection of soldering blocks, bricks, solder rods , pastes , blocks, fluxes & heat paste to make soldering easy.
