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

∙ 11y agoIt depends on what rating of welding machine is being used. Generally industries use 30mA but in some cases if excess tripping is observed a little higher rating can be used after making sure that the welding machine is working fine.

What are the three types of machines used in manual metal arc welding?
I am not sure your question is clear enough but here I go... Stick Arc Welding (AC or DC), MIG (Metal Inert Gas) and TIG (Tunsten Inter Gas). All three of these are the basic metal welding machines.
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
What is a general formula for welding output current and voltage relationship for MMA welding machines?
V= 0.05 i + 10 for mmaw welding v= 0.05 i + 20 for tig welding
What is a welding transformer?
A welding transformer is an electrical transformer used in welding power supply. It pulls relatively low current drawn from the mains power (typically limited to 15 A to avoid tripping the circuit breaker) and converts it to the typical 50 A to 500 A used in arc welding and higher currents used in spot welding. The main difference between a Normal Step Down Transformer & a Welding transformer , is Not only to Step Down ( lower ) the outlet supply voltage and at the same time increase the Available Output Circuit Current, but to be also able withstand the Short Circuit Conditions on the Welding Output Side and especially for the Magnetic ( Iron Lamination Core ) Part of the Transformer. This Magnetic Path difference prevents the Supply side Electrical Circuit from Oveloading , espcially during the Striking of the Arc, when the Welding Electrode & the Welding Job touch to initiate an Arc, after which the Welding Electrode is lifted slightly by Experience, to maintain the required weld flow. A Normal Transformer of equivalent rating will not be able witstand this operation without burning out.

The old welding machines used electromagnetic winding to step up the current for welding rods. What is the new principle inside the welding machines?
The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.

What are the symbols for positive and negative in welding machines?
+ and -respectively.
Which company makes the best welding machine?
Who makes the best welding machines is quite subjective. Some of the best machines are said to be made by Lincoln Electric while others prefer Miller Electric machines.
Short circuit example?
An example of a kind of short circuit is an arc welding.

What kind of welding machines does the US Army use?
Miller
Why is a transformer rectifier often prefferred for smaw?
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
What is typical open circuit voltage for an arc welding machine?
voltage available to the welding current via the machine
