Hand speed

[mattbroomer2000]

Considering MIG welding, if you have a voltage and wirespeed set that provides an adequate weld. If you double these settings, can you just move your hand twice as fast and end up with the same results? As in, can incorrect settings be masked by hand speed.

My two cents worth. To some degree 'YES'. There is a limit on how fast you can actually go and the control you have at that speed. I have done so on alloy, basic synergic setting for 6mm plate cranked up to a 11mm plate setting welding 6mm, but 'moving your ****'. Works pretty well, even if I say so myself

Consult the charts, but IIRC it's not a linear relationship wire speed & voltage doubling.
As far as "more heat" equates to welding the same thickness material faster, yes, to some degree, again
not a linear relationship.

Heat travel won't be as linear as your proposal..

Thanks. I think I am going to turn down my settings and experiment.

Why ?
Slower will put more heat (and more warpage) into a part.
Hot & fast get's it done with less total heat input.

Unless your burning thru with the current settings.

Also, electrical stick out comes into play as well.

So always go as high as possible without burning through?

Position and joint fit-up matters also

There are no hard and fast rules, as you have seen from the postings about your original question.

Be reasonable on these concepts, and it will prove beneficial.
