SOLDERING WIRES TO GIGAVAC HIGH VOLTAGE RELAYS</p>
<p class="black12">Soldering wires to any Gigavac high voltage relay should be easy. The ceramic on a GIGAVAC HV relays are brazed at 810°C in a hydrogen atmosphere. However, good soldering techniques should always be used and heat, flux and solder should be kept to a minimum.</p>
<p class="black12">When soldering a wire to solder pots on GIGAVAC models GH1, GH3, GH5, G2, G8, G15 and G60 series relays, NEVER fill the solder pot entirely with solder. Tin the wire and use minimal solder while soldering to the solder pot. The solder pot is already tinned therefore; it does not require a large amount of solder to make a good connection. If too much solder is used, the solder will fill the entire solder pot which can damage the relay seal. Damage will occur as the result of temperature transients; excess solder will cause a crack in the ceramic to metal seal due to different coefficients of expansion between the solder and the ceramic body. This will allow outside atmosphere to come into the relay and lose dielectric and high voltage isolation between contacts.</p>
<p class="black12">Please wipe off all flux after soldering. Flux left on the outside of the relay can lead to loss of high voltage isolation on the outside of the relay. Do not use flux that contains any acid as this could damage the ceramic surface of the relay.</p>
