Frequently Asked Questions
Which tables does Set 4 fit?
It fits all Siegmund System 28 welding tables (Ø 28 mm bores). It is not compatible with System 16 tables, which use 16 mm bores.
What jobs is Set 4 equipped for?
Based on Siegmund's set list and item descriptions, Set 4 lets you clamp parts down quickly and exactly with the Professional Screw Clamps (including 45°/90° versions); support pipes up to 80 mm diameter in the Ø 50 135° prisms; clamp thin sheet and closed parts that cannot be held from behind, without tools, using the magnetic clamping bolts; set repeatable stops that bolt into the boreholes or slide in the elongated hole (0-100 mm); stop and position large components with the 500 S stops (0-200 mm); build adjustable angles with the L squares; extend the work area past the table edge with the G squares; store and move the tooling on the included tool cart (casters, 240 kg total load).
What does Set 4 add over Set 3?
Per Siegmund's set lists, Set 4 adds 4 Universal Stops 500 S; a pair (left/right) of Stop and Clamping Squares 500 G with rotation angle; 1 Tool Cart, and has more Professional Screw Clamps (14 instead of 10); Professional Screw Clamps 45°/90° (10 instead of 6); Prisms Ø 50 135° (6 instead of 4); Fast Clamping Bolts (30 instead of 24); Magnetic Clamping Bolts 68 (8 instead of 4); Universal Stops 150 L (10 instead of 8); Universal Stops 225 L (10 instead of 8); Stop and Clamping Squares 175 L (8 instead of 6).

How do I keep the table and tooling clean with the included accessories?
The 283999 accessories set includes a bore brush plus CleanBasic and Anti-Spatter spray bottles. Siegmund describes CleanBasic as a water-based cleaner for daily table cleaning whose anti-corrosive ingredients prevent rust under normal conditions; it should not be used if rust has appeared from very high humidity. Anti-Spatter is a non-flammable, water-soluble agent that stops weld spatter burning into the table, so spatter can be wiped off after welding. Siegmund also advises cleaning surfaces and holes regularly and avoiding unsuitable abrasives or corrosive substances.
Do you ship Set 4 across Canada?
