two reasons i can think of:
1 - Probably dont need to, usually welding material of constant thickness.
2 - The transformer is mechanically adjusted on most welders, this means that that there would be a possibility for electricity jumping in the transformer, and premature failure, or fire.
Exceeding a welder's duty cycle can lead to overheating of the welding machine, which can cause damage to the equipment and reduce its lifespan. It can also result in poor weld quality and increase the risk of accidents or injuries to the welder. It is important to follow the duty cycle recommendations to ensure safe and effective welding operations.
A welder is a person who joins metal parts together using heat and pressure. Duty cycle refers to the percentage of time within a specific period that a welding machine can operate at full capacity without overheating.
Welder's glasses work by using special lenses that have a very high optical density to shield the eyes from the intense light generated during welding. These lenses are designed to filter out harmful ultraviolet and infrared radiation while allowing a safe amount of visible light to pass through. This protects the welder's eyes from damage and allows them to see clearly while working.
The current must be adjusted for a particular welding operation to ensure proper penetration, heat input, and weld quality. Different materials, thicknesses, and welding positions require different levels of current to achieve the desired results. Failure to adjust the current can result in poor weld quality, lack of penetration, or material damage.
Stick welding is a type of welding that uses an electrical current to produce an intensely hot plasma arc that melts metal together while adding filler metal, which is what the "stick" electrode is made of. The electrode (or stick) is usually about a foot in length and is covered in flux to prevent atmospheric contamination. It is held by an electrified clamp that the welder runs across the joint to weld.

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.
They sell a spot welding gun that plugs into a DC arc welder. If you have an AC225 or some other AC-only machine, this won't work. In general, tho, spot welders have their own power supplies so you don't need to reconfigure your stick welding machine for this.
The recommended welder amperage for welding stainless steel is typically between 50 to 90 amps, depending on the thickness of the stainless steel being welded. It is important to consult the welding machine's manual and adjust the amperage accordingly for best results.
The other welder will also fail.
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.
Exceeding a welder's duty cycle can lead to overheating of the welding machine, which can cause damage to the equipment and reduce its lifespan. It can also result in poor weld quality and increase the risk of accidents or injuries to the welder. It is important to follow the duty cycle recommendations to ensure safe and effective welding operations.
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.

Transformer type welding machine
A "single hand welder" is any person welding on a job that is not using their own personal equipment. I.E., welding with a company welder or rented welder until you can afford to buy your own welder.
arch welding is a more stable form of welding. it get hotter and creates a stronger bond
