200 amp breaker
This depends on your MIG welder and what you are planning to weld with it. If you are looking for a reliable breaker I would recommend these:ġ20 volts: How Many Amps Do You need For An MIG Smaller welders operating below 30 amps can go with a 30-amp circuit breaker and 10-gauge wire. Meanwhile, welders operating at 30 – 40 input amps will need an 8-gauge wire and at least a 40-amp breaker.

In addition, it is always best to size the wiringĪnd welder circuits based on the input current requirements of yourįor instance, a 240 volt, 40 – 50 input amp welder will need a 50 amp circuit breaker plus 6-gauge wiring. Least 40 amps of current, while 50 amps will need a 6-gauge wire. For instance, an 8-gauge wire can handle at Various conductor sizes with insulation also Plug, you will need a 4 prong or a 3 prong heavy duty outlet. Welder allows a normal home 3 prong outlet. For 3 phase, you will need up to 50 amp breaker depending on its voltage.įor the type of outlets you need, a smaller 115v Thus, for 220v welders you will need to go with at least 30 – 40 amp breaker, meanwhile, for smaller 115v a 20 – 30 amp breaker should be enough. A circuit with 20 amps circuit breaker will need a 12-gauge wire at a minimum. Meanwhile, the wire gauge used in order to wire a circuit also needs to accommodate the specific current that is allowed by the circuit breaker. For instance, a device which needsĢ7 amps would need 30 amps circuit breaker. The amount of current that the devices need.
