Wire speed + Voltage chart

[Brassic]

Hi All
Hi All
I have a ROHR Mig-250mi set up and I would like to know if I can obtain a (Wire seed + Voltage chart) for it.
The speed ana Voltage dial are marked in segments of 1-10 which makes it diffcult,

Nothing in the manual?

Thanks

You can get a rough idea from this very web site, if you do a bit of searching and poking about in the dusty corners.........

MIG Settings Calculator

Estimates the range of mild steel thicknesses you can weld with each setting on your MIG welder.

You can get a red or green LED panel meter cheaply, might be a nice idea to add it to the front panel.

Measure it yourself. Two identical machines could be slightly different.

Wire speed is pull trigger and hold for 6 seconds, then measure the wire and multiply by 10 for inches per min or meters per min (depending on what you prefer)

Voltage is just a case of measuring voltage between the torch and earth when welding. Do not measure open circuit voltage (ie when pulling trigger in fresh air and not welding) that will be higher than actual welding voltage.

Shouldn’t take more than 20 mins to record it all

Hi Rrobson
Can you clarify the voltage measurement, as to where the probes go, one on 'earth clamp', where dose the other one go.
Thanks for your answer

It’s easier if you’ve got a willing volunteer, it’s challenging doing it yourself.
Often you can get to the back of the connection on the wire feeder with one probe then the other onto the clamp.

Hi
The partner just got a job, thank you.
