Alumaweld Trouble

[tomc]

if your not familiar with soldering or brazing it can be a challange,the 2 key things are clean and heat,first take a wire brush and clean the crack very well.the best thing is to take a small disc grinder,or file and open the crack up.then take the torch and run it up and down the crack for a few min.then wire brush again.this will burn off any leftover paint,or oils. now it is time to start fillining in the crack.take the torch and start heating up the area,not just in one spot but the whole thing.(just a note the hottest spot of the torch flame is the tip of the blueish part of the flame)with the rod in the other hand,start srcatching the rod against the area,(dont put the torch flame on the rod tip,all this will do is melt the rod and make blobs,that it fall off) when the material is up to temp the rod will start to melt into the crack,when this happens,you want to stay ahead of the rod with the torch to keep it up to temp.after you filled in the crack,take the torch and go over what you just did,this with smooth out the repair,after it cools take a file to fine tune the repair.hope this helps
