WELD THICKER MATERIALS: With a higher amperage welder, you get to weld thicker materials without any problems.Need to run at the highest amps at all times. Then the duty cycle is probably at 100%, so you do not Welder with a 40 percent duty cycle at 250 amps can get a higher duty cycle if Higher amps work better for material welding since you can cut back on the amps The bigger welders that typically run on 3 phase power. There are welders that can operate at a 100 percent duty cycle. For instance, a smaller 110-volt welder running on 140 amps should only be able to do a 30 percent duty cycle at 90 amps. Then the long duty cycle comes in to play.Īnother problem with the duty cycle is that the more amps you use, the lower is the duty cycle. For most people, this might not beĪ problem, but for those working with complicated materials on huge projects, To weld for longer periods of time in a row. Now, what’s the problem with the duty cycle? Least 3 minutes and requires a 7-minute rest before you can start weldingĭuty cycle of 20 percent at 90 amps, then you can weld continuously for 2 Percent at 90 amps duty cycle, this means that it can weld continuously for at In general, the duty cycle is shown as a percentage. The duty cycle is referred to as the amount of time that a welder can operate at a specific amp. Then you will need to have access to 3 phase power in order to run bigger Lastly, if you are running a small to medium-size business, If you are welding in your garage withĪccess to 115 volts, then this may limit you in what you can get.įarms, you will have the option of 220v welders that allows you to get a higherĪmperage machine. Plan to use the welder on small projects around your small shop or home, then aġ10v welder requiring 30 amps and producing up to 140 should do just fine. So, you will need converted wiring in order to run this kind of welder. Most homes can only run a 200 amp welder. Take note that you’ll need a 3 phase power in order to run a 3 phase welder. To run production for a small business or run the welder around the farm, thenīut, if you want to use the welder for more efficient, high-end production, then a 3 phase welder that should give you anywhere 300 – 600 amps of power or more should be your best, which is unlikely. Only going to weld ¼ inches thick materials or less, then a small 110v welder Welder since it can help you burn hotter and penetrate the material. To weld on thicker materials of around ½ inches, then you will need a 220v Here are a few basic questions to determine how many amps you need for a MIG welder. 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. TITANIUM EASY FLUX 125 AMP WELDER PLUSIn 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.
