strobe light effect of my welder!!

[dvice]

I have a dynasty 350 and have it set up for welding aluminum. I was just going over the mig welds I put on my boat side console I built at home with my 252 mig machine, on the nice new tig welder at work.. I originally set it up at about 100 pulses per second to get a deep fast weld on some thicker stuff a few days ago... well it was going good but I got to a corner and I didn't know if it was loaded with dirt or what . the puddle wouldn't form or get shiny but I saw the blob start to fall in.. the weld was dirty... I cleaned the rod, and I wire brushed it. that corner wouldn't give in. so I read up on the quick reference chart... and it said to get less depth and more cleaning action to set the controls different. So I did.... I turned the pulses down to 10 PPS and I set the amperage control to 200 amp EP and 100 EN. balance was et at 75%. I was welding .093" thick sheet 5052 The welding was fantastic...but the throbbing pulsing was blowning my mind..it was a NOISY pounding strobe light. it was distracting to say the least...it was hard to monitor the weld....all that noise and throbbing light...even if the weld was smooth and easy...

so... is that just the effect of 10PPS that there are so few per second I can see them easy ...

do you just live with that? I had the power set at 150 amps...using a 3/32 lanthanated rod...

what say you?????????

Slow pulse can mess with your sight & concentration...

3-20 PPS are hard on me

Here is Jody on the subject

The effect is called Flicker vertigo, sometimes called the Bucha effect

And it really can foodle your noodle

did you ever get your pulse strobe settings sorted out..............??

well it welded fine at 100 PPS, but I thought I needed more cleaning action because of that problem corner I was welding... so the next time I welded I turned it down to 2 PPS and it seemed fine.....Ill either go with the higher PPS or the super low.....Ill skip that 10 pps...that beat drives me crazy....

thanks

That is an understatement! I have experienced this effect in a helicopter at night on a test flight for a new strobe light installation. It was raining, the wipers were on, and when we tried out the strobes, the flashing reflected off the rain and all the moving parts. Complete mental overload with rotor blades, wipers, and raindrops "stopping" at a high rate. Instant and complete vertigo for both of us; completely incapacitating. If we had not been able to turn off the strobes, I think we likely would have had complete loss of control. Needless to say, the strobe installation was changed. This happened 45-50 years ago and I still vividly remember it as one of the most helpless and frightening moments of my life.
