A rectifier is a type of welding machine. Fairly new development that changes common electrical supplies to voltage and amperage that can be used to weld. It uses less electricity than standard welding machines (usually Transformers). It will require a certain supply (voltage - amperage) that you connect the machine to and should state the minimum requirements somewhere on the machine.
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
A welding rectifier takes in the a/c output of a welding transformer, and the output is d/c. Used with old school welding transformers which were all a/c, in order to get d/c for use with low hydrogen rods etc.

A rectifier is an arrangement of diodes (devices that only allow current to flow in one direction), half-wave or full-wave, that converts AC to pulsated DC. A capacitor (condenser) is used to smooth out the pulsated DC for a more true DC supply. A transformer is usually comprised of two coils of wire around an iron core that changes the ratio of input voltage/current to output voltage/current. It does this by induction (a magnetic field crossing through a coil of wire producing electricity). The Primary coil (the input) usually is a bit thicker and has less windings than the Secondary coil (the output).
it dependsif your going virticle down i would set it at about 100 amps but if your going flat or horizontal i would crank it up to about 125 amps
A welding rectifier is a m/c which converts A.C. supply to D.C.supply. Rectifiers are used for heavy welding work. An invertor is a welding m/c which converts A.C. supply to D.C.supply and then again converts D.C. to A.C. The wt. of invertor welding m/c is less than a welding transformer.

There is no BEST process for all conditions/situations/materials/applications. Easiest to use would probably be GMAW (MIG welding). Most useful for all applications and metals including cutting OAW (Oxy-Acetylene welding) usually referred a to as Oxy-Fuel. Most widely used process is probably SMAW (stick welding) which would also be most portable and cheapest to purchase. GTAW (TIG/Heliarc) is used mostly indoors on thinner and or non ferrous metals ( Aluminum, Stainless Steel, and most alloys. If I were to set up a shop at home I would consider a DC stick welding machine (preferably a rectifier type) and an Oxy-Acetylene setup.

Not really. Frequency in is frequency out, unless there is some conversion circuit in between, such as a motor-generator set or some kind of inverter. You may (and should) notice, however, that a typical welding transformer is rectifying three phase AC to DC, using a full wave rectifier. This results in a pulsating DC voltage where the ripple frequency is 360hz.
That depends on the diameter of the rod if it is 1/8" set your amperage between 125 and 140.
