No, not if you're measuring voltage, and you have the HF turned off. If
you tried to measure the amperage with a standard voltmeter, however
As you probably already know, you'll get different voltage if you
measure it when it is actually welding than when it is open circuit.
Hmm -- I wonder what you would get if you tried to measure it with the
HF turned on -- I'm guessing it would be unpleasant ...
No, it should be fine.
I meter welding machines all the time.
On older MIG machines it is the only way to get a true reading of
voltage and amperage output.
I use a standard Fluke 87 meter with a amperage clamp.
Why would you want to know voltage on a econotig?
BTW the open circuit volts will be much higher than if you are welding
so get a friend to meter it while you weld.
BTW anybody who needs a AC/DC 600 amp amperage clamp probe should take
a look at these.
I bought one and it works perfectly.
Around $50 instead of the usual $150 - $200.
You only have to add the bannana plugs for your meter.
Set the meter to Milivolts DC.
Likely the only reading that would be somewhat accurate is for the AC
setting since voltmeters are calibrated for AC sine waves. High ripple (that
is no or small output capacitors) DC would read wrong.
We tried an ampclamp with mixed results. On the Dimetrics Centaur supply
it works fine, on the Maxstar 152 it was not so accurate. In that case
we use a precision shunt.
The Maxstar 152 runs on an automated lathe welder. We measure the
voltage when we calibrate the Arc Voltage Controller.
Just don't count on getting it away with it. I zapped a Fluke 83 while
troubleshooting a welder because I forgot to turn off the HF before
checking the output.
Fluke's lifetime guarantee is a Good Thing.
Steamer - a volt meter draws micro amps, so it won't steal much current.
The meter might get zapped - I'd have it on the Highest voltage when
striking an arc (HV OSC functional then) but once an arc is obtained, it
should be just the normal voltage.
Might think of putting a Neon bulb across the meter leads. Make a rig -
so the bulb is across the leads - no meter. Fire up the Econotig and see
if it lights up. You should have a resistor in series with the Neon to limit
the current in the bulb - maybe a 80k or 100k resistor. The bulb might have
one already. Radio shack has them - some in 'modules' with resistors.
If the bulb stays on all of the time, it means the Tig is sending out periodic
pulses. If it goes dark during work, then measure the leads with your meter.
Neon fires at about 68 volts. Some resistors and some gases make it near 90.
It all depends on what the volt meter can handle on a specific range. The
might indicate this.
If your meter is one of the cheap ones ($3.99-$39.00) it is probably
average reading not true RMS. If it says its "RMS." reading the value
will be accurate. Average reading meters are cheaper to make and are
calibrated for a sinusoidal waveform not the stuff coming out of newer
My welding machine repair guy uses Simpson 260s for this.
I just gave him two minty 260-8s in a trade. They drop them, but never
burn em out according to him. He laughed when I started to cringe when
he was testing out the Tig/Stick 250 Lincoln I bought out of his junk
"Gunner, you are the same ridiculous liberal f--k you ever where."
I have one like that and it doesn't do DC amps.
To dial in large wire feeds I need DC amps.
For example: 1/16" dual shield wire has a sweet spot at 23 volts 200
To get the amps right you have to dial the wire speed while somebody
Most modern 1/16" dual shield wires work best at 23 volts, 200 amps.
Being able to dial in the machines faster is a real time saver.
1/16" dual shield is thge one we go through at school by tyhe pallet
load, so it's settings are tattooed on my brain.
It wouldn't be hard to figure out the others.
I may have some time soon to dial in some other wires and write them
Yes, but where is the leg of roast beast?
I don't know how I am supposed to answer all these welding questions
