For a 120-amp, 120-volt arc welder, you typically need a double-pole circuit breaker rated for at least 30 amps. This allows for the necessary current flow while providing adequate protection against overloads and short circuits. It's also important to use appropriate wiring to handle the current safely. Always consult the welder's manual and local electrical codes for specific requirements.

Can i use a transformer with my arc welder?

Yes, you can use a transformer with your arc welder, but it must be compatible with the welder's voltage and amperage requirements. Ensure that the transformer can handle the load without overheating and is rated for the specific type of welding you are doing. Additionally, verify that the connections and safety features are appropriate for your setup to prevent damage or hazards. Always consult the welder's manual for specific guidelines.


What is an arc voltage in a circuit breaker?

ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.


What size breaker for a 50 amp stick arc wilder?

For a 50 amp stick arc welder, you typically need a 60 amp double-pole circuit breaker. This allows for the necessary current draw while providing a safety margin to prevent tripping under normal operating conditions. Additionally, ensure that the wiring used is appropriately rated for the load, usually 6-gauge copper wire or larger, depending on the distance and local electrical codes. Always consult a licensed electrician to ensure proper installation and compliance with local regulations.


What is the difference between Air circuit breaker and Vacuum circuiut breaker?

"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.

Is there any copper inside an arc 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.


What is the difference between an arc welder and a stick welder?

Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It's used for welding thicker metals of 1/16 inch or greater.

Why does the arc breaker keep tripping?

The arc breaker keeps tripping because there is a fault in the electrical system that is causing an arc, which is a dangerous electrical discharge. This triggers the breaker to trip in order to protect the circuit from potential damage or fire.


Is a welding arc as bright as the sun?

That that would depend on what welder you are using. But most welders do have a arc that is brighter than the sun


What is the purpose of an arc fault breaker and how does it differ from a standard circuit breaker?

An arc fault breaker is designed to detect and prevent electrical arcs, which can cause fires. It differs from a standard circuit breaker by specifically targeting and interrupting dangerous arc faults, whereas a standard circuit breaker mainly protects against overloads and short circuits.


Can you use 10-3 with 30 amp breakers at 90 foot to run a 225 amp max arc welder?

No, using 10-3 wire with 30 amp breakers is not suitable for running a 225 amp arc welder. The wire size and breaker amperage should be appropriately matched to the current requirements of the welder to ensure safety and prevent overheating of the wire. In this case, a larger wire size and breaker amperage would be needed to support the 225 amp maximum draw of the welder.
