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 a 50 Amp welding machine, it is recommended to use an Earth Leakage Circuit Breaker (ELCB) with a capacity of at least 63 Amps to ensure it can handle the load safely. Additionally, the ELCB should have a sensitivity rating of 30 mA to provide adequate protection against earth faults. Always consult local electrical codes and a qualified electrician to ensure compliance and safety.
The percentage of time a welding machine can be used continuously is typically referred to as its duty cycle, which is often expressed as a percentage over a 10-minute period. For example, a machine with a 60% duty cycle can be used for 6 minutes of welding followed by 4 minutes of cooling. Duty cycles vary based on the type of welding machine and its specifications, with common values ranging from 20% to 100%. Always refer to the manufacturer's guidelines for the specific duty cycle of a given 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.
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.

7018 electrodes should be used with DC positive polarity. This means the electrode holder is connected to the positive terminal of the welding machine, resulting in better arc stability and smoother weld deposits.
