Not all LN-25s have a contactor. This is the part that turns off the welding power to the gun until you pull the trigger. Very convenient a lot of times, but adds to the cost, weight, and complexity a bit. If you are not laying the gun on electrically conductive parts (steel catwalk for example)... -
But there's also no problem being sure that #10 is sufficient. It is. Look at the duty cycle of the machine. It's impossible to draw that high output for more than a couple minutes at a time, so the Code allows the wire to be sized accordingly, just like the cord on the machine itself.

What caused you to replace the liner? Are you having the same symptom before and after?Leave a comment:

What is the input amperage of your machine at the thicknesses you are welding? No way will it need a #6 extension cord. This is doable.Leave a comment:

Well, the Bobcat still needs a feeder to do MIG. Some would rather have a self-contained MIG that can use shore power or generator power; even if it's not portable like a dedicated SuitCase feeder for the engine drive.
But yeah, if always going to use the engine drive, there are some big...Leave a comment:

What exactly did they say? That generator power is bad for the machine, or that your generator won't provide enough power to use the MM252's top-end capabilities? If the latter, it will still work, just not at its potential on the big stuff, so no different (except in duty cycle) than using the next...Leave a comment:

Not enough info to answer that kind of question. The Multimatic 200 is modern and fancy and provides its own welding power from any land power or generator. The LN-25 is a mainstay in the industry and bulletproof. Since its welding power comes from your engine drive (usually), you aren't hauling...Leave a comment:

You would plug it into the engine drive's auxiliary power receptacles. It would provide its own welding power the same as if plugged into shore power.Leave a comment:

The Spoolgun was probably worth close to that. The cylinder of gas was worth it all by itself. Smoking deal...Leave a comment:

The thermal overload switch is to protect the machine from melting after you've already exceeded the duty cycle by a significant amount. You need to pay attention to how long you have an arc on if you are welding at currents that will approach your duty cycle. The more amps you are using, the shorter...Leave a comment:

The kitchen equipment part is no longer the same company. Here is where you want to start for those: https://www.hobartcorp.com/Leave a comment:

Never used it, but I've seen it lots of times. Probably all the big makers will have some. Blue Demon brand is available on Amazon.Leave a comment:

He's not asking how to weld. He's asking different ideas for explaining how wire speed controls amperage (heat) into the weld.Leave a comment:

Yeah, you'll need to provide some specifics. What part were you welding on and what happened?...Leave a comment:

Thanks for posting the resolution! Glad it's working!Leave a comment:

With Stick welding, the setting is amperage, and the voltage fluctuates depending on the arc length.
With wire welding, the main setting is voltage, and the amperage is changing depending on the wire feed speed (which is also adjustable) and the wire stick-out length.
That's...Leave a comment:
