Silicon is added to the tig rods in production. Use a gas weld rod which does not have the silicon and the weld will be full of porosity.

It's best to use silicone on silicon.
yes
you want full field while starting 0 Ohms and maximum series on armature then bring the armature resistance to zero as it approaches running speed its a good idea to run with armature at 0 ohms armature will use the same amount of power as the resistor If you want to run at more than base speed you can now weaken the field
The armature voltage is a critical parameter in the determination of performance characteristics for the DC machine. The armature voltage has been shown to be proportional to the magnetic flux density per pole and the armature speed. Thus, the armature voltage will also exhibit nonlinear behavior when saturation occurs. The analysis of DC machine performance typically requires that the characteristics of the armature voltage saturation be known. This information is typically provided in a plot of the armature voltage vs. field current (magnetization curve) for a given operating speed

The children all made a small armature with soft metal rods.
Iron and steel were very tough material back then and it was the only material people back in the 1800s could use that could hold up the sewing machine.
In electrical machines such as motors and generators, the field winding is responsible for producing a magnetic field within the machine. This magnetic field interacts with the armature winding, which carries the electric current and generates mechanical power. The field winding typically has fewer turns of thicker wire compared to the armature winding, which has more turns of thinner wire to handle higher currents.
Someone uses a banding machine for strapping purposes. It is also used for packaging the products. There are metal banding machine, plastic banding machine, steel banding machine, paper banding machine, hand-held banding machine and edge banding machine.

The recommended type of hose to use for connecting a washing machine to the cold water supply is a stainless steel braided hose.
Interpoles are similar to the main field poles and located on the yoke between the main field poles. They have windings in series with the armature winding. Interpoles have the function of reducing the armature reaction effect in the commutating zone. They eliminate the need to shift the brush assembly.
In DC series motor, field and armature are in series. so we use only two points. They are line and armature. therefore we use two point starter.
