Product Applications |
Durafix Easyweld will work with propane, butane, mapp, oxyacetylene or any
fuel source as long as the material is brought up to 389'C ( 732'F ) before applying the rod. The material must be cleaned with a stainless steel brush only. Unlike conventional aluminium welding techniques, brazing with Durafix Easyweld is very simple. There is only one rod type, which works on all grades and alloys of aluminium. You do not need to identify the specific alloy or choose a brazing filler to match. All you need are the parts to be repaired, the Durafix Easyweld rods and a heat source. Just follow these four steps for a perfect brazed repair.
Preparation
Brush surface of the part to be repaired thoroughly under heat to break up the surface coating of aluminium oxide.
|
 |
Heating
Heat the aluminium parts hot enough for the rod to flow without the aid of the flame, thoroughly tinning the surface.
To test for the correct temperature, rub the end of a rod onto the work surface while heating, the rod will flow when working temperature is reached.
|
 |
|
Tinning
Brush tinned surface under heat, thoroughly filling the open pores. This creates a film of rod over the weld or repair area, which aids bonding and strength to the weld.
|
|
|
Filling
With sides thoroughly tinned, flow in enough rod to fill the vee. Be sure filler fuses with the tinned surface without melting the aluminium.

Leaky radiators spell trouble both for the effecient running of your vehicle and the environmental damage. Constantly filling up the coolant in your car’s radiator, creates the risk of it overheating and the coolant you leak can cause environmental damage. Your cooling system will also become damaged with the fluctuating coolant levels.
A radiator is a very fragile piece of equipment, usually made from very thin gauge aluminium with either plastic sides or aluminium. Anything that hits it can easily puncture it and cause a leak.
With metal tanks, repairing any damage is very difficult and often costs more than a replacement unit. Well not any more!
Durafix Easyweld can help you repair the damage in a few seconds, with minimal fuss. Using a handheld torch, heat the damage area - REMEMBER - this is very thin gauge aluminium, it will get to working teperature in a few seconds.
Apply the heat and rub the end of a rod onto the damaged area, almost immediately the rod will flow. Simply go over the damaged area and take the heat away. It will be cool in a few minutes, with your hole effectively fixed. When its cool fill with water and test again.
Because the rods don't drip like conventional solder, going over the holes won't cause blokages in the pipes, so the radiator will be as good as new, and for the cost of a few cents and a few minutes of your time, you have a perfectly working radiator.
The same is applicable for fixing cooling units, condensors, and air-conditioning units.
Durafix Easyweld rods work on any non-ferrous metals, except stainless steel. Suitable for aluminium welding, die-cast, zinc, copper and brass. You can join these dissimiliar metals together. They will even work on galvanized steel.
This is a very versatile product and a valuable addition to any toolbox and workshop. You can use Durafix Easyweld with any open flame torch.
How to Weld Zinc Alloy and Zinc-based Die-cast Metals
Preparation
Vee the broken edges of the zinc alloy to about 45 degrees, clean the surface of any plating or scale back from edges of the vee 1/8 of an inch.
|
 |
|
Heating
Heat until it starts to flow. Turn flame parallel to surface and with side of flame, hold at this heat. Heat welding rod to same temperature.
Now with both bases and welding rod at this temperature, touch rod to the break and rod will flow into vee, thoroughly fusing the parts.
|
|
Repairing
Repeat operation until break is completely filled. Any eccess can be ground and polished after cooling.
Be sure to kick rod into weld to break down skin resistance as the filler rod will lay on surface and will not fuse if only heat is applied.

Replacement parts are expensive as are repairs, not to mention time consuming. It is also difficult to do repairs in the open with conventional welding equipment............not any longer. Durafix Easyweld is the alternative. Small, versatile and easy to use, you can repair parts on the water, or in the field. All you need is Durafix Easyweld and a handheld torch! How to repair a propeller
Preperation
Grind the damaged part of the blade to remove any sharp edges and paint.
Now brush the damaged area throughly with the stainless steel brush, to break up surface oxide and remove paint.
|
|
Heating
Heat the blade hot enough to flow the rod without the aid of the flame.
Tin the flat (not bevelled) side and attach a temporary support of stainless steel or iron. Turn and tin the bevelled side.
|
|
Building the blade
Build out the blade slightly larger than its original size. Leave it to cool naturally. When it cools, the stainless or iron support will simply fall away.
Now grind damaged edges to a 45 bevel. Pitch propeller to standards.
|
|
The Results
Let cool, then grind to proper standards.
Results? ... a well prepared wheel without porosity ready for you to balance and paint! |
