We are mechanised piercing and cutting some 1" mild steel plate with a 1650. g3
I know its not recommended to pierce but if you had to...
Do you have any tips ?
We're getting a lot of metal splatter on the shield... this is the worst bit.
Thanks

Drill pilot holes where your pierce points are.
I also use a 1650 and, cut some 20mm plate a couple of years ago, complete with many pierces and, wasted so many consumables, I drew a line in the sand and, now don't pierce anything over 16mm.

You will not be able to pierce 1" plate with a Powermax1650 without damaging the shield and nozzle. It's maximum pierce capacity is 3/4". Drilling pilot arc holes is the best way to achieve 1" cutting...or edge starting. We normally recommend a 200 Amp plasma for the ability to pierce 1" materials.

We want to cut a 40mm hole in 25mm plate, we are going to drill a 5mm pilot hole right on the circumference of the circle and start and finish inside the drilled pilot hole... what size hole would you drill ?
Is this the best way of doing this ?
A boss will be welded in the 40mm hole , so the 5mm hole will be filled with weld. If there's anything left of it !
The hole is over size so some taper isn't going to matter.
Any hole larger than about .100" (2.5 mm) will work fine. Make sure the nozzle orifice starts on the edge, make sure you program a pierce delay time to allow the arc to stabilize before movement starts.
