2-wire receptacle? I pulled up a few pics of old ones but they didn't appear to have that option. Lots of machines in that era just used a 2-wire contactor circuit for a wirefeeder that was also plugged in to the 120V AC supply. I had an old Millermatic 80A that plugged in that way to welding power... -
And I missed that you had two different machines in that post. Thanks for clarifying.Leave a comment:

Good to know. It would probably be my machine of choice if I needed that in my shop.Leave a comment:

The duty cycle will not stop the machine from welding. You must keep track and do it. When the thermal switch on the machine cuts out, it's because it's already been overheated from significantly exceeding the duty cycle. Then you let it cool, and hope nothing was damaged. Don't rely on the thermal...Last edited by MAC702; 02-03-2023, 12:33 AM.Leave a comment:

What is your table and clamping system?Leave a comment:

Yes, but the duty cycle will be low on that class of machine for that size material. It depends on how often you need that capability and how much productivity you need when doing it.Leave a comment:

Check the strength of the knob that holds on the spool. One of my wirefeeders is susceptible to that tightening up, and I will experience that exact symptom. And every time, it takes me days of cursing before I remember how I fixed it the last time.
If you can push the wire by hand through...Leave a comment:

Ditto on the details. We need them.
Also, what is the condition of your ambient light? The darker the room and work area, the brighter (relatively) the arc will be, regardless of shade setting.
That said, be prepared for bad news. Most of us are using hoods that cost a few...Leave a comment:

"Set up per manual" actually doesn't help us. We want to know every switch setting and pics if available of machine and your work.
Is the work lead clamped to the weldment?
Is there a "purge" setting on that machine?Leave a comment:

The clamp on my HH210 is very sufficient for its purpose. My old MM130XP, on the other hand, did get a new clamp. But the last decade-plus they've been doing good clamps on these.Leave a comment:

Will it work when plugged back in to the 120V receptacle?Leave a comment:

I think it will work fine if you do the fitment as required. Like you say, it's just stiffer than necessary. I've welded lots of plate and haven't noticed a difference in weldability. I can't think of a good enough reason not to do it if that's what is much more easily available to you.Leave a comment:
