hey guys. got my 200sx in and set it up for trial on some aluminum. welded quite well out of the box. only problem was with the regulator. after initial setting of 17-18cfh and approx 10 min welding, the flow rate crept up to 25cfh. i made sure the regulator was backed out before turning my bottle on initially and setting the flow rate. i'm wasting some argon. anyone else had this or am i missing something?

Not normal. Contact Longevity.

sounds like you have a defective flow meter

Definitely get another one.

Yep contact longevity about it.
I have a few regulators, but the one I use the most is this one

We also have them at school and they work great. It might be a cheaper option than paying to ship it back and waiting.

You could try taking the sticker off the centre and turning pressure down abit in the thought that if it is at the diaphram maybe it is sticking, and go back to your flow knob and turn it all the way in and out a few times, new regulator perhaps an o-ring is not seated well and allowing leakage.Flow is set by pressure matching orfice diameter, I turned mine down abit because their is always a burst of pressurized argon at startup and pressure is set high to force gas through any kink in lines a little high in my veiw.Sorry not much you can do but send it back.

that htp is cheap and actually quality flowmeter for its price point

congratulations you have officially de-calibrated your flow meter
a flow meter is set at a certain PSI and the flowmeter works ONLY with that specified PSI for the scale to even be accurate

thanks for all the posts guys. emailed longevity this morning. might get another flowmeter from lws if i'll be without for a while....thanks again

I think that is exactly the same one I have on order. I've heard it is a pretty good regulator too.

I have one also. It is a great deal, but you need to open the valve very very slowly, because on this flow metter the low side (gauge) is not protected when the knob is closed, and the ball gets a hefty burst of Argon.

I should have advised to never change a regulator setting without first marking the position, Longevity uses locktite; one of the great things about having your own rig is your free do try whatever you want.Their is exceptional article about flow characteristics at netwelding.com. that might be worthy of a post down the line.

Thanks for the tip. I'll have to keep that in mind!

BASE ENTRY REGULATOR SUITABLE FOR VERTICAL GAS VALVE OUTLETS - BOC


Suitable for MIG & TIG applications, this gas regulator will fit all types and sizes of UK Argon and Argon/CO2 Mix gas cylinders (excluding Air Products "Integra" cylinders which already have a regulator built in to the cylinder valve).


Solid brass construction with twin gauges, one showing the pressure inside the cylinder, and the second showing output pressure calibrated in LPM (Litres Per Minute) for an accurate flow setting.


300 Bar rated for service at increased gas cylinder pressures, so fully compliant with the latest gas cylinder regulations; the gas hose outlet is standard 3/8 inch BSP right hand thread.
