Repairing damaged copper is now easy with the help of Durafix easyweld-

When heating metal to high temperatures you must take sensible precautions-Welding Gauntlets and Goggles must be worn.

Keep children and pets well out of the area, when you heat up metal it can remain hot for long periods of time so do not leave a piece of hot metal unattended at any time. You cannot tell that metal is hot by looking at it, if you leave it unattended someone else may pass by and pick it up with disastrous consequences.

easyweld

Here we are going to fix a hole in a copper immersion heater cylinder using the Easyweld kit pictured on the left.

Do Not use Easyweld on:

Do not use Easyweld on Magnesium. {To test for Magnesium shave a small piece of metal and apply the flame. If it burns white, then it is Magnesium}. Do not use on Pewter or tin as they will melt before the working temperature is reached.

The rods will not work on Stainless Steel or any other type Steel (except galvanised)

damaged copper cylinder

Here we have purposely cut a 3 inch long slit in a copper cylinder to see if it can be repaired with Easyweld.

brush copper

Start by cleaning the area with the stainless steel brush that is supplied with the kit.( do not use any other type of brush or it will not work ).

heat with blowtorch

The metal now needs heating to 389oC.

Easyweld will work with propane, butane, mapp, oxyacetylene or any fuel source as long as the material is brought up to 389oC ( 732oF ) before applying the rod.You know when you have reached the correct temperature as the rod will melt on contact with the heated metal.

DO NOT APPLY THE FLAME DIRECTLY TO THE ROD

feed easyweld into slit

Feed the rod into the hole, using a circular motion, keep the flame 1 1/2- 2 inches away from the metal. The rod will melt and fill the hole. (flame from blowtorch not in picture as I was taking picture with other hand)

Allow the metal to cool naturally, do not cool it in a water or oil bath.

repaired copper cylinder

The purpose made slit has now been repaired.

If you are going to try this you must test the cylinder before you use it again.
