Arrange the pieces of metal that you wish to join.
Place a 1mm spacer between the pieces to be joined so that there is a small, even gap along the brazing seam.
Clamp the pieces so that they remain stationary during the brazing process.
Clean any debris from the edges to be joined with a wire brush.
Feed the copper-silicone MIG wire into the MIG welding gun.
Join the Metal
Set your MIG welding gun to the lowest voltage setting but use faster wire feed speed setting.
Angle the brazing tip 45 degrees from vertical with the tip of the welding wire pointing forward.
Slowly push the welding tip forward in a straight line, filling the gap with the weld bead.
Continue the brazing until you completely join the pieces.
