weld time should be set to the minimum amount of time that
will completely fill the hole. If the spot weld is not flat and
has excessive metal build-up, there is an excessive amount of
spot weld time, the wire feed rate is too fast, or the power is
not high enough. The correct power setting, spot weld time
and wire feed rate will produce spot welds which will lie flat
and require little, if any, finishing.
Hole Filling
Before you begin to fill holes, you must look at the reason
why there are holes. If the holes are due to burn-through, you
should remember that this was caused by too much heat input.
Therefore, if you are welding a seam and burn-through occurs,
continue welding and finish the seam. This will give the burn-
through area time to cool and make it easier to fill the hole.
It is not recommended to try to fill holes over 1/2" diameter;
weld in a new piece of metal.
First, the perimeter of the hole must be built up. This is
accomplished by randomly placing puddles of metal (similar
to manual stitch welding) around the perimeter of the hole
(See Fig. 8B). Once this has been completed, again place
puddles around the area which has just been welded (See Fig.
8C). Continue to lay in the puddles until the hole is filled
(See Fig. 8D & 8E). The power setting for hole filling is one
to two settings below seam welding.
Welding Aluminum
It is possible to weld aluminum with your MIG 2400.
Depending on your application, you may be able to get away
with pushing aluminum welding wire through a 10ft welding
gun, using our aluminum welding kit #40011-T#1, or it may
be necessary to use the RSG250-2400 spool gun. Pushing
aluminum welding wire though a 10-ft welding gun is not
a foolproof situation. There is the possibility the welding
wire will bird’s nest while you are welding. You have to
determine at what point does it make economic sense to
invest in a spool gun. We generally recommend using the
standard 10’ welding gun if you would only be doing 1 small
repair job per month. If you are welding more aluminum
than that, you might want to consider the spool gun.
The RSG250-2400 spool gun will allow you to get 25’ away
from your MIG 2400. If you will be repairing aluminum
trailers, the spool gun is probably a must, as it will allow you
to weld on the trailer without having to lift your Mig 2400
into the trailer. Since the spool gun has the wire and the drive
roller right in the handle, the wire is only getting pushed 6"
and it is highly unlikely that this gun would birdnest using any
welding wire.
Due to the difference between aluminum and steel, a few
simple changes must be made prior to welding aluminum.
