Dynamics

[Daneishwelder]

Hi guys I've got a Kempi 323r kempact. It's digital so I can be more accurate with speed and volts but also there's a + & - dynamics toggle but I don't know what dynamics it means could any body enlighten me please

This any help?

Straight from the Kemppi manual my friend.

1. Control knob for welding dynamics
Dynamics function controls the rate of rise of current when the filler wire is in short circuit with the welding plate. This control adjustment is necessary due to the alternative welding parameters, materials, wire sizes, gas types and current values used.
The welding dynamics scale is –9 to +9. Negative values make the rise of current slower, which results in a hotter and more fluid weld characteristic. Positive values make the rise of current faster, which results in a colder welding condition. This can result in more spatter during welding depending on the filler wire size and type used.


How to find the optimal dynamics setting?
Start by setting '0' and make a test weld after selecting the correct wire feed speed and
voltage values. Fine tune the welding arc by trying different values in the negative (-) and positive (+) sides of the dynamics scale

That's exactly what I kind of wanted to see thank you very much mate big help

No worries whatsoever

Do you weld? If so what kind

 

[Tom Orrow L]

Indeed I do, mostly stick & TIG but i'll occasionally tinker with a bit of MIG. Not producing quality welds like your own but not terrible

 

[Daneishwelder]

Any photos of your welds? Haha there not that great there's always better welder a than you out there I always bare that in mind. I really want to get in to practising tig and so that if I'm honest

Not really fond of taking pictures of my weld's as they ain't anything special to look at, I can lay a nice stick bead in most position that'll get a peeler pretty much 9/10
I'm currently working on TIG lap joints and then moving onto some T joint practice just to hone skills.

TIG is a beautiful skill to learn as its very pleasing to the eye and it can be incredibly useful for specialist jobs that might come your way. I believe it also pays a bit more dosh to be a skilled TIG welder than MIG/MMA.

 

[Daneishwelder]

Yeah the pay is better but it's more a factor of the skill in interested in. I've attempted a mig like tig weld a few times trying to imitate that of ztfab I don't know if your familiar. But I'm yet to get anywhere near the quality at the moment with my gear

What's going on with the weld that appears to be floating? Was the metal cut out around it or did you use copper backing or something?

It's 2 5mm plates put together c section |_| |_| like this mate just playing
