Four metal welding clamps with adjustable level screws on a plain background

Firstinfo Tools Co., Ltd.

Firstinfo Tools Co., Ltd. Auto Body Butt Joint Welding Clamps 4-Piece Set

SKU CH-RQG7-PSEEP

A four-piece set of butt-welding clamps that hold panels edge-to-edge with near-zero gap, featuring patented level adjustment for flat alignment and 0-0.11 inch range to join dissimilar thicknesses

  • Product typeAuto Body Tools
  • Precision butt welds with minimal panel gap
  • Full weld penetration through edge-to-edge holding
  • Patented level adjustment joins dissimilar material thicknesses
  • Flat alignment of top or bottom panel surfaces
  • Adjustable 0 to .11 inch range for exact fit

Four-piece butt-joint welding clamp set

This set contains four clamps designed for auto-body sheet-metal work. They hold panels edge to edge with almost no gap so the weld can fully penetrate the joint. The patented level adjustment aligns the top or bottom surfaces of panels that differ in thickness. Straight or curved panels are both accommodated.

Replaces improvised clamping methods

The clamps remove the need for makeshift fixtures when joining door skins, fenders or similar panels. They are worth adopting when a shop wants repeatable, flush butt joints without gaps that weaken the weld. Builders who need a second card for simultaneous operations will find only four clamps in the box.

Sustained workshop use

The metal construction resists heat and mechanical stress during repeated welding cycles. Level adjustment stays accurate across many setups because the mechanism locks at the chosen setting. No cooling downtime is required between joints, so throughput remains steady during a full panel-replacement job.

Questions about this item

How much clearance is needed around the 0-3 mm level-adjustment mechanism on each clamp?

The patented level adjustment moves 0-3 mm either side, so allow at least that much space beyond the jaw faces for the knob to turn freely during alignment.

What is the correct sequence for tightening the clamps on a curved panel to avoid misalignment?

Loosely position all four clamps, use the level adjustment to match the panel heights within 0-3 mm, then snug each clamp in a cross pattern so the panels stay edge-to-edge with almost no gap.

Which parts of the clamp set are most likely to wear and need replacement after heavy welding use?

The level-adjustment threads and the jaw faces that contact the panel edges take the most heat and force; inspect them for galling or deformation and replace individual clamps if the 0-3 mm travel no longer stays true.
