Stupid thing to do to a brand new welder

[FusionKing]

This week I have spent more time at Airgas than anybody should
I was pointing out how my new 350P didn't have a lifting eye and they said don't do what a guy I know that has another shop down the road did....

He welded a lift eye on a brand new MM212 with itself!!!


Which made me bring up the point of what if... you had a machine like a 212 mounted to your table or truck bed??? I don't see much difference really.

What do you guys think about that?

Well I don't know anything about the new electronic mig machines, I never even used one.
But in my old school world, I have welded on the welder with the welder.
You want to have a good ground close to the weld.

Stepping up several years, my ranger and vantage 300 have sat on my truck and I do a lot of welding on the back.
I also haven't fried the computeror the alternator in my Ford by welding on the bed of the truck. Or my phone.

The stupid thing is building a welding machine that doesn't have a lifting eye..

new welder

Never have had any problems but always ground the workpiece as close as possible. On newer engines like the series 60 Detroit Diesels I've been told always unplug their little black box. My Miller manual says the machine must be isolated, be interesting if anyones had any problems?

[FusionKing]

I guess I should point out that the machine was brought in DOA
But I certainly agree that no lifting eye is just plain cheap IMO

[trstek]

my 210, use the bucket on the tractor to move it, now that you mention it, a lift hook would be really nice...

[FusionKing]

They should offer a lifting kit

[walker]

A MM212 weighs 190 pounds, not light but certainly not too tough to move around. I have moved much heavier pieces by myself, by hand. How does that saying go, give me a lever and I can move the world, of course I now have a forklift!

Weld on welder

Besides on how much someone can pick up. Anyone fry their machine grounded to their deck?

[J hall]

I see that the lincoln power migs also are without lifting eyes. that makes no sense to me at all.
Not having a lifting eye on a welding machine limits the possibilties.

[FusionKing]

To me it just says they want it just in the shop and not moved out on the job.
I am on the verge removing the wheels of putting the 350P on my truck. The arc is so much more superior than anything I've had ahold of that I really can't imagine not having it at my disposal.

[fun4now]

the syncro 200 has one, seems strange the largest MIG would not ??

Can you explain, specifically, why you consider this stupid?

Is there a lifting eye inside the machine, under the cover? Some welders have eyes inside the machine. P&H had internal lifting eyelets.

One reason you never weld on a welder, is that often they contain transformers. Anything with an induction winding should not be welded.

When you ARC or MIG weld, you are only using DC current from the power supply, to melt the rod. The flow of electrons in Reverse polarity now called DCEP, from the power supply is flowing from the work piece to the electrode only.

The rays you see from the cathode (electrode, or ARC rod), are ARC rays (Anode Rectified Cathode) rays. They are flowing against the power supply. ARC welding creates a liquid diode just like a mercury diode is created.

Inside a battery the first electrical devices, we had as a modern civilization. The electrons flow from the anode to the cathode inside the battery. That means that of course the internal cathode being hit with electrons from the internal anode, becomes the external anode. The internal anode becomes the external cathode. This is enough to confuse the best. And still does.

When you ARC weld in Reverse polarity, now called DCEP incorrectly in my opinion. Originally the anode is the work piece, and flows to the cathode the ARC rod. When the ARC rod ARC's, it becomes the anode, and is called the "Anode Rectified Cathode".

You actually create a battery like device at the end of the electrode, the ARC rod, you create a liquid diode.

This is basic Universal Science as was taught before World War Two. I received lectures from a Universal Scientist in school as an honors student. This understanding is what isolated our elements, and created the science we used to do all good things.
This science explained the atom and its workings, when the atom had no neutrons. Chadwick the fellow who invented the neutron was banned as a universal scientist for being lazy.

Neutron was actually a German term describing the atmosphere around the earth or an experiment. It was noted by great German scientists that the atmosphere was capable of either supplying or receiving energy from an experiment. And yet remained neutral if there was no experiment or excitement created.

When a TIG welder using Straight polarity now called DCEN sees a beam or a ray, from the tungsten to the work piece, he is watching electrons flow rather silently from the power supply only. Without the ARC effect.

Why do I bring this up. Because if you weld on an induction device you could possibly hit the coils/windings with high voltage and amperage and even high hertz from the ARC. Any ARC is capable of 30,000 volts.

Anyone that has ever gotten a shock through their shoes, while holding onto a piece of rusty steel being ARC welded. Knows that the ARC welder power alone, will not shock you through your dry shoes or boots. But that ARC on a rusty part can.

Welding induction devices, you could create a very powerful magnetic field. As well as create events in the magnetic field that could adversely effect you or the surroundings.

If the induction device is a motor it may reach very high rpms and self destruct. These are some reasons not to weld on induction equipment.

Over the years I came across a couple different brand welders that you could not touch earth ground to the welding ground. One in particular was a three phase motor powered brush generator. It would start the ground clamp wire smoking. But yet the drain on the unit was almost nothing.

There were heating elements inside the welding unit that would glow a bit, when you connected the welding clamp to earth ground. I cannot say if this is how it was new but that is how it was used. This unit passed inspection at a defense plant.

I believe the Hobart Cyber TIG also could create a strange effect to ground. However I did not have the machine from the factory, it was also used. But it was kept up well and certified at a defense plant.

One day I was stuck between a van with a running gas powered DC welder, and the railing or work piece. I was soaking wet in the rain with a one piece work suit on. The van and the work piece were certainly not of similar polarity. I was yelling to my partner to shut it down, shut it down. I was making the funniest motion you ever wanted see. The van was painted, there was no raw metal exposed. But the large wet area of my work suit fixed that. Ha-ha.

I am sure anyone that does handicap ramp rails on site, knows that if you are in a sweaty "T" shirt and you are laying on your back, and you touch the electrode that you will get a tense feeling in your back.
