These rings slide over the
drag shield on your plasma cutter. This essentially takes one Plasma
Stencil and turns it into three different sizes, which is important for
precise metal fabrication. Most of our Plasma Stencils have zero kerf offset,
which means the final hole is larger by the width of your plasma cut.
That loose fit is nice for general fab work, but to get precise you will
want material to sand for final fitment and that's where the Offset
Rings come in handy. They are slotted which makes it easy to swap sizes
for different plasma cutting tolerances.
Offset Rings - for .380", .430", .580" drag shields
- .060" offset ring makes a snug fitting hole with minimal clean up.
.120" offset ring makes a little undersized hole and will require a
good amount of sanding or could be machined to a perfect fit.
Conversion rings - These convert odd sized drag shields to work with our Plasma Stencils. The kit comes with
three rings, one converts to our plasma stencil size, another thats
.060" larger and the third is .120" larger.
.297" size fits - most of the cheap Chinese plasma cutters and European style torches with a drag style tip
.312" size fits - Thermal Dynamics cutmaster 42
.500" size fits - Hypertherm 30 Air, max 40/43 and 800/900 models. Miller Ice 50/55 and 125c torches
fit the rings on your plasma cutter, sand the offset ring to final length and then
cut, grind or file the flutes in the ring to match your drag shield.
This allows one ring to fit a lot of different drag shields, which helps
to keep the price down. Machined from 6061 Aluminum and made in USA.
