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

How can I prevent arc strikes?
Preventing Arc Strikes Between Work Piece and Welding table
Arc strikes can happen between any two materials on a welding table, but are more likely to happen with aluminum. This article focuses on aluminum, but the general principle applies to other materials as well.
Causes of Arc Strikes When Welding Aluminum
1. High electrical conductivity
Aluminum conducts electricity very well, 5-7x better than steel, so current spreads widely through the sheet. Any small gap or sharp contact point between the aluminum and a steel table can become an unintended arc site.
2. Thin aluminum forms micro-gaps
When heated, thin aluminum sheets expand and can lift or warp slightly, creating small air gaps. These gaps make it easier for the arc to jump to the table underneath.
3. Aluminum oxide layer causes voltage buildup
The aluminum oxide layer acts like an insulator and raises the breakdown voltage. Once this layer is punctured, the arc may jump through the underside of the sheet toward the ground path.
4. Poor ground clamp placement
If the ground clamp is far away, attached to a dirty area, or poorly connected, the return path through the table can become more favorable, increasing the risk of arc-strike between the workpiece and table.
5. High-frequency TIG increases underside arcing
High-frequency AC (used for TIG welding aluminum) can couple through thin aluminum and jump to the table, even when there is little or no visible gap.
6. Dissimilar metals concentrate electric fields
The aluminum-steel interface can concentrate the electric field at sharp points or edges, making it more likely for an unintended arc to start there.
How to prevent underside arc-strike
- Clamp the ground directly to a clean, oxide-free area on the aluminum workpiece.
- Avoid continuous high-frequency settings when they are not needed.
- Allow the sheet to float evenly (or clamp it evenly) on the surface instead of over-clamping sharp edges that can concentrate current.
- Use non-conductive spacers (such as phenolic, ceramic tile, or composite pads) between the aluminum and the steel table.
- Use a sacrificial aluminum underlay instead of placing the work directly on bare steel.
Why is the FA75 System better than the others?
What makes the 3/4" Hole System Superior to 16mm and 5/8"
45% larger hole cross section while still allowing 2” spacing on table and 1” spacing on accessories.
3/4" System
5/8" & 16mm System
What makes the 3/4” Hole System Superior to 28mm
2” hole spacing on tables vs 4” hole spacing.
- 92% more holes
3/4" System
25 Holes Per 12"x12" Section
28mm System
13 Holes Per 12"x12" Section
Explaining FA75 Fixture System
- The entire Fireball Table system is based on 3/4” diameter hole sizes on a 2” grid pattern.
- All fixtures are also based on a 3/4” diameter hole size and use 1” thick by 2” wide fixtures.
- Tables and plates come in different thicknesses for different applications and price points, but ALL Fireball 3/4” fixtures are compatible with ALL Fireball 3/4” tables whether it’s a 3500 lb heavy duty table or a portable 50 lb plate.
Why 3/4” Hole System
- 45% larger cross section compared to ⅝” and 16mm holes means strong bolts, stronger clamp.
- Largest hole size while still having a 2” grid pattern on the table and 1” hole pattern on fixtures.
Why 2” Grid Pattern
- The 2” grid pattern is the ideal hole density to get clamps and fixtures where you need them.
- Many fixtures require 2 bolts to properly align them. Having a 2” grid pattern allows shorter, more compact fixtures compared to 4” hole spacing. This is even more important when fixtures have slots to bridge the gap to the next hole, and is the difference between a 4” on a 2” grid, vs an 8” slot on a 4” grid.
Fixturing System
FA75 - Ø3/4" x 2"
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.
FA625 - Ø5/8" x 2"
FA16 - Ø16mm x 2"
FA28 - Ø28mm x 4"
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.

How are tables shipped?
Ships Inside a Crate
Only availbale to ship in the contiguous United States.
The contiguous United States refers to the 48 U.S. states that share a border, plus the District of Columbia. This excludes Alaska and Hawaii, which are non-contiguous states. The term is often used interchangeably with "continental United States," though officially, "continental United States" can also include Alaska.
What are Factory Seconds (Blem)
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.
