When you refer to a 200 amp welder you are talking about the output side of the welder. What you have to do is find out what the input voltage and current of the welder is to calculate the size of a generator needed to operate the welder.
A welder generator can be purchased from several online retailers. Northerntool website has generator prices ranging from $1,500 - $27,000. Depending on a person's criteria for purchase. Their number one best selling Welder generator cost $4500.
Your welder needs 20A at 120V for full output. This is 2400W, but you should always add a little extra margin, so I would recommend a 3600W generator.
No, the output voltage is too high.
no
arch welding is a more stable form of welding. it get hotter and creates a stronger bond
1. Some home made welder links below.
Generators are rated in watts or kilowatts. The formula for watts is W = Amps x Volts. To size a generator for the welder the voltage of the machine must be stated.
No, unless you can set it low and can be assured that it wont use more than say 4000watts, the welder might momentarily use more power than what you set it to, it should not wreck the welder i would imagine unless it is a fancy mig welder or something, set the welder low you should be fine but for high end use she should be firing out 8 or 9kw so keep it low if you must.
If the power tool has brushes to bring the current to the armature it is classed as an universal motor. It will run on DC as long as the voltage is the same potential. On a welding machine the 120 volt receptacle is a DC output and the grinders, drills, etc that are plugged into it work fine.
Its 'a' generator ! And no, a generator still needs fuel to run
The factors that determine how long a propane generator can run are the size of the propane tank, the size of the generator, the brand of generator, and what is being used under the generator's power.
