A. The Draper 24577 is a magnetic holder for positioning and holding workpieces at the correct angle during tack welding and fabrication. Magnetic holders provide instant, tool-free positioning on ferrous surfaces.
A. Jaw capacity is listed in the Technical Specifications section of the product listing. Check this against your material section size before ordering — a clamp that cannot open fully to grip your material is useless.
A. Magnetic holders only work on ferrous (steel) materials — they will not hold aluminium, stainless steel, or copper. Use mechanical clamps for non-ferrous work.
A. The jaw faces may leave light impressions on soft or polished surfaces. Place a thin piece of scrap material between the jaw and the workpiece to protect finished surfaces. On structural work where marks don't matter, use the clamp directly.
A. For simple butt or corner joints, two clamps is typically enough. For frame welding (square section, angle iron), four to six clamps gives good control. Build your collection gradually based on the joints and sections you weld most frequently.
A. Keep magnetic clamps away from the arc — high heat reduces magnetic strength. Position magnetic clamps away from the weld zone and allow to cool between passes.
A. The Draper 24577 is manufactured to standard fabrication tolerances. For critical angular accuracy, verify with a square after clamping and before tacking — clamps hold position but thermal distortion during welding can shift angles slightly on large assemblies.
A. Keep strong magnets away from inverter welding machines — the magnetic field can affect the sensitive electronics. Position magnetic clamps on the workpiece, away from the machine and welding leads.
A. Pre-weld cleaning removes rust, paint, oil, and mill scale that cause porosity, weak fusion, and spatter. Post-weld cleaning removes slag and discolouration for inspection and appearance. A wire brush is the most common tool — use stainless steel brushes on stainless steel to avoid contamination, and carbon steel brushes on mild steel.
