2000 Watt, minimum. Related note, some types of electronic equipment have start-up, or inrush current. Electric motors are notorious for this. A 15 amp electric motor can have as much as 7x inrush current for the half-second or so when it first starts up.
To successfully run your AC/DC 225/125 welder you would need a minimum of a 15,000 watt AC generator.

Likewise, Will a 5000 watt generator run a welder?
It appears that a 5000 or 6000 watt 230 VAC generator is large enough to operate my AC/DC 225/125 welder using a 1/8 inch diameter E6010. … If you try and weld with this combination you will most likely experience the electrode being hard-to-strike and also the electrode frequently sticking to the work.

How much power does a stick welder use?
A typical welder uses 7 -12 kilowatts. If you use that for 15 minutes per week, you could estimate about 1 hour of “on-arc” time per month, (plus the “off-cycle” power used when the welder is “on” but not in use.)Apr 16, 2012

Will a 7000 watt generator run a welder?
Subject: Re: 7000 Watt Generator, what will it handle? Size wise it should do fine with the MIG, Occasionally a generator and a load like a welder with an active rectifier section will have problems with instability. The factory units are tested as the combination welder/generator, but all bets are off in the others.

What size breaker do I need for a stick welder?
The circuit breaker that is most often used on welder installations is a double pole 60 amp size (in which case the feeder conductors must be sized accordingly) although the 50 amp size is usually more than adequate to serve the light-duty work for which most workshop units are used.
How much power do you need to run a welder?
Input Power Requirements Primary voltage: 208 – 265V AC, single-phase, 50/60 Hz. Minimum circuit size: 208 – 230V/25A. Recommend circuit size: 208 – 230V/40A (or 230V/50A)May 18, 2019
How many amps does a stick welder use?
200 amps
How much watts does a welder use?
Most 115V welders need at least 15Amps, 20A is better. 115 x 15 = 1725 watts. And Max. 25′ of 12ga extension cord.
What size breaker do I need for a 250 amp welder?
Welders operating at 30 to 40 input amps require a 40-amp breaker and 8-gauge wire. What size breaker do I need for a 250 amp welder? For a 250-amp circuit breaker, this means a magnetic trip adjustment range of 1000 to 2000 amps.
How big of a generator do I need to run a 110 welder?
Re: What Generator Wattage Is Needed to Run A 115V Welder 2000 Watt, minimum.
How many watts does a welding machine use?
Most 115V welders need at least 15Amps, 20A is better. 115 x 15 = 1725 watts. And Max. 25′ of 12ga extension cord.
How many amps does a 220 welder need?
A 220v welder will take about half the amperage of a similar 110v welder. 90-100 amps is fairly common, but you can find smaller (and larger) welders. An air compressor will probably take a lot less current, maybe 20-30 amps for 220v or 20-50 amps for 110v.
What size breaker do I need for a 220 welder?
A circuit with 20 amps circuit breaker will need a 12-gauge wire at a minimum. 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. For 3 phase, you will need up to 50 amp breaker depending on its voltage.
Will 100 amp service run a welder?
The 100 amp panel will be fine-you just need to size the specific breaker according to your max draw on your welder; which should be listed on the welder itself or online.
