Arc welds can be porous, but that looks fine to me.This is one of the outer corners. This is probabl;y the best one. I am using Oerlikon Citorex 3.2mm rods and I find they make me look better than I am.

I've never made a watertight vessel before - this looks pretty watertight?
Are arc welds ever porous? I've only ever seen porosity with mig
It sounds a bit like a tuning fork
What thickness will it cut ?I sold my Gerber Sabre 408 for a song and now I can afford the Myplasm CNC for idiots setup. Let this be considered a live review.
Everyone asks this about mine when they are making enquiries about work.What thickness will it cut ?
Cheers guys.
The thinnest material I use is 3mm.
I bought motors this morning., The guy I sold the Gerber to, and his dad, are CNC nuts, the dad has a cnc plasma cutter. Anyways point being, I can put questions to them, which is good because I need all the help I can get.
I bought stepper motors this morning. According to the two fellas, 200 oz-in steppers would have been fine, so I went a bit higher than that. I'll make it nippy eventually, for right now I just want it to work at all.

I would use ServosIf I was building that I'd be using Rack and Pinion with Nema42 hybrid steppers (1200-1600 Oz/per) with belt reductions of at least 5:1.
I would use Servos
I reckon 400w servos with reduction would be more than enough for a plasma. Only reason I used bigger is because I had them.
The servos ae getting very cheap nowadays and I was almost tempted to get a few sets as spares, just £2-300 for a drive, motor and 30m cables.
