Simply put, yes.
Look at electric arc welding. Think about ship-building. You have a thousand guys putting electricity through that hull while welding on it at the same time, perhaps even with different polarities, even while people are walking around inside!...

You won't get the nearly ready-to-wipe-and-paint welds that GMAW welding gives you, but you will greatly appreciate the other benefits of FCAW. You can weld in nearly any weather and on much dirtier material, as well as a bit thicker if needed.
.035" wire is the most common by far,...Leave a comment:

Like Ed says, the electricity wants to go back to its source to complete the circuit. Just like water wants to go only down in the drain. Your drain is also an air vent, and has a penetration through the roof to stay vented to atmosphere. How come when you run water into the sink, whether it uses the...Last edited by MAC702; Today, 12:14 PM.Leave a comment:

Yes, correct!...Leave a comment:

To clarify, for a 120V circuit, even though it is alternating current (AC) and the electrons are going back and forth, only one of the two circuit conductors is supplying the pressure to do so. It pushes at 120V and then pulls at 120V. The other, the neutral (grounded conductor), is just allowing the...Last edited by MAC702; Yesterday, 07:40 PM.Leave a comment:

In DC, like on a car, the chassis ground is part of the circuit.
I didn't know if it would help or hurt, so didn't bring this up yet, but the neutral is actually called the "grounded conductor" because it is the current-carrying conductor that is at ground potential. It's only...Last edited by MAC702; Yesterday, 06:42 PM.Leave a comment:

Welcome aboard!
Which Handler do you have? I'm guessing the "50 amp" might be the input power plug configuration?Leave a comment:

The typical household hot is 120 V to the neutral. The hot is also 120 V to the ground. Neutral and ground are 0 V to each other.
Are you familiar with the steam cycle? Or pressurized plumbing versus drains?
Think of the "hot" as the pressurized water lines, and the...Last edited by MAC702; 01-15-2020, 06:50 PM.Leave a comment:

Agreed. Somehow we can email old manuals to people within a day, but we can't keep our house clean?
The inability to flag this clever new spam using a group post of some kind should be a loophole that was fixed the first day, too.Leave a comment:

Very good point to make sure gets mentioned and understood.
A welding "ground" is also different from both. English is awesome....Leave a comment:

You need them separated at all other points because you don't want the ground to carry any current UNTIL it is the fault path. But you need that fault path to carry fault current immediately and sufficiently to trip the circuit breaker.
Having the neutral and ground be parallel paths,...Leave a comment:

Practice running stringers first (not weaving). Go with more wire speed and less travel speed. See what happens.
Make sure you have sufficient task lighting to see the weldment around your arc.Leave a comment:

You had a decent one at 3/35 also, but the 4/40 looked more consistent. I think you need to spend more time in the puddle before weaving or moving to get the penetration you want in the toes.Leave a comment:

Not really. The only time it might matter is that the 120 Hz strobing of a fluorescent can sometimes make rotating machinery look motionless at the right RPMs, which can be dangerous when not merely annoying.Leave a comment:

Task LIGHTING. Getting lots of light directly on what you are doing, as opposed to just the lights illuminating the room.Leave a comment:

4/40 is starting to look pretty good. Make sure you have a LOT of task lighting on your weldment so you can see the joint clearly while welding.Leave a comment:

I'm not seeing beveling helping a whole lot on 1/8" lap joints, even with a 120V machine. What are you making that has you 'wanting this to be a high strength weld and have good penetration and fusion?'Leave a comment:

Pics help a lot. If you aren't going too quickly, you have a good joint design for a very good weld, if your steel is clean. You are at the top end of your machine, so let that puddle sink in a bit, and don't exceed your duty cycle if you have a lot of this to do.Leave a comment:

Better questions get better answers, and waste less time.
Did it work fine before, or has it never worked for you? New machine?
Tell us everything you are doing. Every setting. What polarity? What wire?
Take the time to write a complete question. It's worth it....Last edited by MAC702; 01-09-2020, 10:32 AM.Leave a comment:
