It can be used to welding and melting various metals such as platinum,gold,
,silver.copper.titanium,stainless steel. And it also can be used to polishing surface of organic glass,hectograph.
A welder is one.
A welder
Like any mechanical tool, machine or similar engineering equipment, an arc welder will have lots of different materials inside it. An arc welder is an electrical machine and any electrical machine must have wiring inside it. Most electrical wiring will be made of Copper. So yes, there is likely to be some Copper inside an arc welder.
The type of welder is dependant on what you want to weld with the machine. Welding heavy steel will take a bigger machine than one that is used for light metal.
Welder as in the person: A welder joins metal together using Oxy-fuel or more commonly Arc processes. Welder as in the Machine: A welder converts electricity from your home/workplace and turns it into suitable voltage and amperage for welding operations. That is to melt the base metal and add filler metal (electrode) In the case of gouging the arc is transferred between the carbon electrode, melts the base metal and a stream of compressed air carries the molten puddle away. A Welding machine may also be a fuel driven machine often used on job sites away from electrical connections.

MIG Small machine like Lincoln SP 135 is nice.
To calculate the current you need to take theWatt rating of your welder and divide this by the voltage youhave setthe machine at- this gives the amperage. So for a 1440 watt welder running at 12v the current would be: 1440 watt/ 12v = 120 Amps
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
Alternating current flows from the welder through the torch into your welder, through the grounding cable, and back into your machine. It then flows in the exact opposite direction. The result is deep penetration, and removal of impurities in the weld. It is used mainly on aluminum and alloys. Direct current has both a positive and negative setting: the difference is the direction of the current. One flows from the welder, through the torch, through the material and back into the ground; the other flows in the opposite direction.
Generally the title of 'fitter' is applied to the person who does the layout, preparation and positioning of parts to be welded. They may also do the cutting of the parts to be assembled and the tacking the parts in place. A 'welder' then comes behind the fitter and welds the parts together. A 'fitter and welder' does the entire job and all the aspects of it.
