LS+ Magnetic Welding Holder

Magnetic Welding Holder LS+ is an effective iron and steel workpiece positioning solution in mechanical workshops, helping welders quickly secure angles without manual effort. In metal fabrication, aligning steel bars and box tubes before tack welding requires high precision to prevent warping. The Magnetic Welding Holder LS+ series was developed to solve this challenge through strong magnetic force and a flexible multi-angle design.

Structural Features of Magnetic Welding Holder LS+

Magnetic Welding Holder LS+ features a structure consisting of permanent magnet blocks securely encased in steel, connected by heavy-duty rivets to maintain stability in harsh working environments. This design allows the tool to withstand radiant heat from weld joints at a safe distance without reducing the internal magnetism.

The highlight of the Magnetic Welding Holder LS+ series is its ability to support multiple popular welding angles including 45 degrees, 90 degrees, and 135 degrees. Mechanics can flexibly rotate workpieces to create accurate right-angled, acute, or obtuse joints. The center of the holder typically features a cutout hole for easy access of the welding electrode to spot-weld the workpiece when necessary.

Technical Specifications and Popular Sizes

The Magnetic Welding Holder LS+ is divided into various nominal sizes to suit the weight and dimensions of different iron and steel workpieces. Understanding holding force specifications helps users select the right equipment for actual workshop tasks.

• 3-inch Type (Code LS32000): Compact size with a nominal holding force of 25 lbs (equivalent to approx. 11.34 kgf), suitable for holding thin steel box tubes and small door frames.
• 4-inch Type: Medium size with a nominal holding force of 50 lbs (equivalent to approx. 22.68 kgf), commonly used for iron furniture workshops and medium frame trusses.
• 5-inch Type: Large size with a nominal holding force of 75 lbs (equivalent to approx. 34.02 kgf), specialized for joining thick steel pipes and factory frames.

It should be noted that the actual holding force of the Magnetic Welding Holder LS+ depends heavily on workpiece surface conditions and actual contact conditions. Rusted, painted, or grease-stained steel surfaces will significantly reduce the magnetic suction force. The manufacturer recommends users to treat this strictly as an angle alignment tool during tack welding, and never use the Magnetic Welding Holder LS+ as a heavy object lifting device to ensure workplace safety.

Practical Applications in Mechanical Workshops

The most common application of the Magnetic Welding Holder LS+ is assisting welders in erecting iron door frames, railings, staircases, and industrial racks. Instead of needing an extra pair of hands to hold things square or using bulky clamps, workers simply place the Magnetic Welding Holder LS+ flat against two edges of the steel workpiece.

Thanks to natural magnetism, the Magnetic Welding Holder LS+ automatically clamps details together at exact 45, 90, or 135-degree angles. This operation significantly saves alignment time while minimizing dimensional errors caused by workpiece shifting during initial tack welding.

Magnetic Welding Holder LS+ – ANGLE ALIGNMENT AND WORKPIECE HOLDING FOR TACK WELDING

The Magnetic Welding Holder LS+ is a welding angle magnet designed to position iron and magnetic steel workpieces during alignment and tack welding. The product holds workpieces at 45°, 90°, and 135° angles, making it more convenient for workers to assemble frames, iron doors, and shelves.

Available in three size options: 3", 4", and 5", corresponding to nominal pull forces of 25, 50, and 75 lbs. Users can choose based on workpiece size, contact area, and job requirements.

The arrow-shaped design with angled edges allows flexible workpiece arrangement during processing. Actual holding force depends on material surfaces and contact conditions.

How to Choose the Right Magnetic Welding Holder LS+

Choosing the correct size of the Magnetic Welding Holder LS+ directly determines workpiece stability throughout workshop fabrication. Mechanics should base their decision on the dimensions and weight of the material to be welded for accuracy.

• For residential fabrication tasks such as making window frames and doors using small zinc box tubes, the 3-inch Magnetic Welding Holder LS+ is a well-fitted choice, easy to handle in tight spaces.
• For factory frame structures and industrial worktables using heavy shaped steel, prioritizing the 5-inch Magnetic Welding Holder LS+ is recommended to ensure firm grip against mild mechanical forces.

Instructions for Using and Storing Magnetic Welding Holder LS+s

Proper use of the Magnetic Welding Holder LS+ not only improves work efficiency but also extends the lifespan of this hand tool. Workers should clean welding slag, iron filings, and dirt adhering to the surface of the Magnetic Welding Holder LS+ after each work shift to maintain stable suction force.

During operation, gently place steel workpieces onto the surface of the Magnetic Welding Holder LS+ rather than heavy impacting that could crack the internal permanent magnet block. After use, store the Magnetic Welding Holder LS+ in a dry place, avoiding direct contact with corrosive chemicals or prolonged humid environments.

Frequently Asked Questions About Magnetic Welding Holder LS+

Can the Magnetic Welding Holder LS+ be used for stainless steel?

The Magnetic Welding Holder LS+ series only works effectively on magnetic materials such as regular iron and steel. Most common residential stainless steels like 304 stainless steel are non-magnetic or have very weak magnetism; therefore, the Magnetic Welding Holder LS+ will not attract them or will lack sufficient force to hold stainless steel workpieces.

Does the holding force of the Magnetic Welding Holder LS+ decrease over time?

The permanent magnet block inside the Magnetic Welding Holder LS+ retains its magnetism for a very long time if used and stored correctly. However, subjecting the tool to heavy impacts that deform the steel casing or exposing it to excessively high heat sources for extended periods may diminish the magnetism of the Magnetic Welding Holder LS+.

Can the Magnetic Welding Holder LS+ be used to hoist heavy iron workpieces?

The manufacturer designates the Magnetic Welding Holder LS+ solely as a welding angle alignment support tool. Never use the Magnetic Welding Holder LS+ to hook, hoist, or lift heavy iron plates moving overhead because the surface holding force is not designed for load-lifting purposes.
