I've been wanting one of these forever... Crossfire 2x2, paired with a PrimeWeld Cut60. First cuts went perfectly, other than some operator learning.

DXF file uploads welcome, share your designs!

I made 4 of these for axle-side shock tabs supports. Corner hole for drainage, U top to clear the shock eye. 1/8 steel, 1.6" wide.

Experimenting today with cutting holes on the plasma table....we will be using the table to cut round bolt holes in 3/16" AR450. So, time to learn before we waste the expensive stuff :)

The 3/4" diameter hole (top/right) was drawn at 0.780. Import into sheetcam, process as Inside Offset, set a perpendicular lead in of 0.390 (0.780/2), overcut at 0.20. Feed rate set at 50% of normal for 3/16" sheet. (can do this in sheetcam, or on your table program....FireControl in my case). Set the program Origin to the center point and you can effectively line up the plasma tip to dead center of your hole. With these settings, the 3/4 bolt dropped in cleanly.

I'll likely reduce speed to 25% for the AR plate.

Similar oversize amounts for the 1/2", 9/16" and 5/8" were used. Some tweaks were made so the 50% number didn't end up at .2125 or something.

Note the failures where the bolt just didn't quite drop in ;)

I bought a Cut 60 last year with the idea it could be used on a table like the Crossfire. If I get into a larger garage one day I will definitely own one. Keep up informed on your long term use with it.

The hand torch is awesome....in your hand. PITA on the table, so a good machine torch will be ordered when they come into stock later this month. This one is VERY recommended....


The issue is "squaring" the torch any time it gets removed. PITA. So disconnecting/reconnecting to switch between hand and table keeps the table aligned properly.
