Exothermic Welding is used for earth mat conductors
yes , it is required so that the leakage current from transformer/electrical windings to metallic enclosure of welding machine does not harm a person/operator & the current is rooted back to earth bajaj mahesh, asst fire & sec officer
which oil use for arc welding machine
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
It's an engine driven generator like a Ranger, correct? They already come set up to be used as either welding machine or generator when they come from the factory.

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.
For welding 8 mm thickness metals, common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding (SMAW - Shielded Metal Arc Welding). The choice depends on the type of metal and specific requirements.

Dc welding can be used for non consumable electrodes with consumable electrode heat is transferred from electrode to work by molten metal. Ac welding is desirable for aluminum and magnesium, because it helps break up oxides AC is more stable than Dc.
I would say that SMAW (stick) is still the most widely used process. The GMAW (mig) process has gained a wide acceptance in construction and fabrication and may even have surpassed stick welding in many situations. Unfortunately with mig welding the machine has to be close to the welding site. Dragging a welding lead into and around fabrications is still much easier than moving a mig machine.
Usually the rating of a welding machine is expressed on the DC output side. What you need to state is what the input in voltage and amperage is. It is this side of the welder that is connected to the supply breaker. On the nameplate there will be a voltage, amperage both stated for an AC supply connection.

If by gas welding you mean-oxyacetylene welding. The difference is just that arc welding requires a darker shade of lens. When oxyfuel gas welding (OFW) usually a shade 5 lens is recommended. When arc welding, a minimum of shade 10 lens should be used (actually shade should be determined by amount of current used).
A plastic welding machine is used on vehicles to heat up and mold plastics. Though there are many other machines that specialize in heating plastic as well.
