Description
Accelerate your collision repair workflow with the Telwin Digital Puller 5500 Duo (Item Code 828131). Engineered for high-throughput automotive body shops and panel beaters, this microprocessor-controlled electronic spot-welding system features a dual-gun design that eliminates constant tool swapping during complex sheet metal dent extraction.
Delivering up to 3,800A peak output, the Digital Puller 5500 Duo comes equipped with both an automatic contact gun and a manual trigger gun connected simultaneously. The intelligent digital LCD display automatically regulates welding parameters according to the selected tool, ensuring repeatable, factory-grade attachment of stars, washers, and pins without burn-through on modern thin-gauge automotive steels.
Key Features & Benefits
-
Dual-Gun Simultaneous Connection: Connects both an automatic contact gun and a manual trigger gun at the same time—switch between fast inertia pulling and precision stud welding instantly without swapping cables.
-
Intelligent Microprocessor Control: Automatic adjustment of spot-welding current and duration based on the selected tool profile and panel gauge.
-
3,800A Peak Output Power: Delivers high instantaneous pulling current for secure washer welding, wavy wire attachment, and heavy-gauge panel traction.
-
Multifunction LCD Digital Interface: Clear digital display allows rapid tool selection, parameter monitoring, and fine adjustment of welding time down to the millisecond.
-
Versatile Auto & Manual Triggering: Use the automatic gun for ultra-fast contact-initiated pulling, or switch to the manual gun for controlled, high-precision placement on structural lines and edges.
-
Complete “Ready Box” Consumables Kit: Outfitted straight out of the box with pulling stars, slotted washers, rivets, carbon electrodes for metal shrinking/upsetting, and ground attachments.

Frequently Asked Questions (FAQ)
Q: What is the main advantage of the “Duo” configuration?
A: The Duo setup allows you to keep two different guns (such as an automatic contact gun with a slide hammer and a manual trigger gun with a washer/stud tip) plugged into the unit at the same time. This eliminates downtime spent unscrewing electrodes or changing cables mid-job.
Q: How does the Automatic Contact Gun work?
A: The automatic gun initiates the weld instantly upon touching the tip to the bare metal panel, eliminating the need to pull a trigger. This makes rapid-cycle pulling with star washers significantly faster.
Q: Can this machine perform sheet metal shrinking / thermal upsetting?
A: Yes. Using the included carbon electrode, the Digital Puller 5500 Duo can heat and thermally shrink stretched metal areas to restore structural tension and panel shape.
