The Heavy Duty table is built for fabricators who push the limits of what a fixture table can do. Its one-inch cast iron top, deeper skirt, and robust construction make it the right choice when your work demands that the table maintain absolute flatness no matter what you put it through. Heavy Duty tables are measurably flatter than Standard Duty tables out of the box and are engineered to maintain that flatness under the most demanding loads.

The Fireball Cast Iron Tables are the best all around tables on the market. They combine the strength of 1” thick top and sides used for heavy duty tables with the more finely spaced 2” grid pattern you find on light to medium duty tables. Gray cast iron naturally resists weld spatter, does not form burrs on the surface, resists deformation, and once machined flat, it stays flat.
Combined with the patent pending Fireball 3/4" Fixture System, Fireball tables and fixtures are the fastest, simplest, and most secure fixture system.
CHOOSE THE HEAVY DUTY IF YOU:
• Straighten frames, chassis, or large structural assemblies — where the table needs to resist significant warping forces
• Regularly work with large, heavy weldments — that generate substantial twisting or pulling loads
• Frequently expand work off the sides of the table — using large cast iron accessories and blocks
• Need the highest level of long-term flatness retention — under repeated heavy production use

The Fireball Tool fixture system is superior to others on the market. It features blocks that can be used in many different ways to maximize their usage. It also can be incrementally adjusted to ensure maximum coverage as efficiently as possible while others fail to reach certain distances without a complicated fixture.
Versatility & Strength
No other system on the market combines both the strength of 2"x1" fixture profiles with the versatility of 1" hole centers. This let's you place fixtures with the agility of a thinner table using 5/8" and 16mm holes, but with the strength of a big table using 28mm holes.
Always Stay Square To the Table
Other systems use a two hole slot as standard, which doesn't allow both adjustability and keeping things square. Fireball's tooth block, which forms the basis of most accessories spans 3 holes, which allows adjustment while always keeping your fixtures square with the table.
Tabletop Construction
1” thick Gray Cast Iron on top and 1” thick sides, additional reinforcement ribs underneath. Machined flat on all 5 sides to within +/- 0.0025” per 24” x 24” area. Side apron on the tables are 8” tall with 3 rows of holes.

Choosing The Table That’s Right For You
The Fireball 3/4 fixture system uses the same fixtures for all tables. So whether you are starting with a mobile 1/2" thick plate or a truck sized heavy duty table, all fixtures work on both tables.
X Frame
X Frame tables feature a rigid cast iron base with a nitrided, 1" thick tool steel plate on the top surface for added wear resistance.
- Tool Steel Plates that can be reversed or replaced
- Each plate features leveling screws to dial in flatness
- P20 Tool Steel with Nitride Finish for HRC50 hardness provides extra wear resistance
- Railroad Track style ribbing for extra rigidity
Heavy Duty
Heavy Duty Series Tables feature single piece, cast iron construction for best rigidity and flatness with 1" thick top and sides.
- Machined from single piece casting, 1” Thick Top and Sides
- Our most rigid table series
Standard Duty
Same construction method as heavy duty series, but with 1/2" thick top and sides.
- Machined from single piece casting. Holes machined to ½” thickness, with extra material and thickness on the underside
- Railroad track style ribbing for extra rigidity
Pro Line
Ultimate work station solution that keeps everything organized.
- Machined from single piece casting. Holes machined to ½” thickness, with extra material and thickness on the underside
- Reinforced railroad track style ribbing on perimeter for extra rigidity

Avoid Arc Strikes with 3 Steps:
- Always ground directly to the workpiece.
- Clamp the workpiece down.
- Ensure you have a clean table surface
Workpieces often make poor contact with the table, which increase the likelihood of arc strikes. Grounding directly to the work piece prevents this.
Clamping the work piece down helps to maintain better contact between the work piece and the table.
Having a clean table surface also ensures you have better contact between the table and the workpiece.
Why These Steps:
- Workpieces often make poor contact with the table, which increase the likelihood of arc strikes. Grounding directly to the work piece prevents this.
- Clamping the work piece down helps to maintain better contact between the work piece and the table.
- Having a clean table surface also ensures you have better contact between the table and the workpiece.
FACTORY SECONDS
Producing large castings with perfect surfaces is a difficult task. The larger the surface area, the more likely there is to be some air pockets or voids during the casting process that only show up after machining.
Our castings are optimized to produce a high quality top surface, but even a typical table will often have some small imperfections on the top or side of the machined surfaces.
When the tables experience a higher number or severity of surface defects we designate them as factory seconds and sell them at a discounted price.
Customers who order factory seconds will receive photographs of the table before shipping.
