Gutted i could not get down to surprise you. That was my plan but it all fell apart......Interesting day at at R Tech
The wife has more CAD ability than me
I met up with the Lad that builds the tables
Very impressed
Some good video to come
This is 16mm (I think) steel I did a wee while back, pretty happy with it, almost no dross
Just been a bit nosey, what plasma are you cutting that with hypertherm 65 ???, and what torch height controller are you using think I read on another forum the rtec table use a Taiwanese thc maybe wrong don't know much about the table.
I am using a TecArc Opticut 65, it is good but I sometimes think I should have gone with a Hypertherm.
The THC I am using is miniTHC from Russia.
I love my Hypertherm 45xp, Andy at Rapid welding just sent me the flush cut conversion for it
Yes it is on the opposite corner I am still learning with this enjoying it though so many parameters to play with it pierced the 12 mm plate no problem@doubleboost is the earth on your table on one side? From the part you cut on tonight’s vid the arc is being drawn over to one side making a tapered cut ....when I set our table up they told us to put an earth connection in each corner to stop this.
The cut looks good need to do the pierce a bit further in from the edge of the holeYes it is on the opposite corner I am still learning with this enjoying it though so many parameters to play with it pierced the 12 mm plate no problem
Plasma will always cut with a bevel on one side as far as I am aware, it is due to the swirl. If you look at Hypertherm site you will see the direction of travel that you should go to leave the straight on the part and the bevel on the scrap.
On my Trafimet it is a bit of a pain as the swirl ring can be put in either way so I have to be conscious of the way I put it back, either that or I have to take a test cut.
Other things that can cause a bevel are torch height being too high or too low and also worn nozzle.
As for piercing holes I have actually found that a straight lead in works well for me, kind of goes against the grain as I am used to milling where a circular lead in is usually better.
Yeah you can get a bevel in the cut (reduced substantially by good set up) but the whole cut is ****** over because the arc can pull towards the earth if it is in one position
