How to Use TW6902 Dual Gun Drawn Arc Stud Welder – 1 1/4 Max Diameter: Complete Guide

Step 1: Initial Setup and Installation

This is not a plug-and-play machine for a standard 120V outlet. You will need a qualified electrician to install the correct 3-phase disconnect and circuit protection. The unit requires 230, 460, or 575 VAC. Ensure the incoming power is properly sized. Use heavy-gauge cables for the ground and lead connections. Position the welder on a level, stable surface that can support its 1,136-pound weight. Connect the two stud guns to their respective output terminals.

Step 2: First-Time User Guide

Power on the unit using the main disconnect. The dual digital displays will illuminate. Familiarize yourself with the “Time” and “Current” controls for each gun. Start with the manufacturer’s recommended settings for your stud size and base material. It is wise to perform test welds on scrap material before starting production. Adjust the settings in small increments based on the weld appearance.

Step 3: Core Functions and Daily Use

Load the chuck with the correct collet and stud. For optimal results, ensure the base material is clean and free of oil, rust, or heavy mill scale. Position the gun perpendicular to the work surface. Press the gun firmly down until the stud contacts the material, then pull the trigger. The safety interlock will prevent a double-hit. The stud will be drawn up, an arc will strike, and the stud will be driven into the molten pool. For two-operator use, simply connect the second gun and set independent parameters.

Step 4: Advanced Techniques

The stepless controls are the key to professional results. For thin materials, reduce current and slightly increase time to prevent burn-through. For heavy structural steel, maximize current for deep penetration. Use the “stud job counter” to track production runs. Experiment with different lift distances to change arc characteristics. The machine handles weld-thru-deck applications exceptionally well, but ensure the deck is properly grounded.

Step 5: Maintenance and Care

Regular maintenance is simple. Inspect the gun chucks and collets daily for wear and replace them as needed. Check all cable connections for tightness. Periodically blow out the interior of the power source with clean, dry compressed air to remove conductive dust. The manual recommends lubricating the gun’s internal mechanism monthly.

Step 6: Troubleshooting Common Issues

If you experience poor weld quality, first check the ground connection. A poor ground is the most common issue. If the gun fails to fire, inspect the trigger assembly and cable continuity. For inconsistent arc starts, check the collet and stud for debris. If the unit shuts down, it may have tripped an internal breaker; allow it to cool before resetting. For complex electrical issues, contact Tru Weld support. You can find further maintenance details in our welding equipment maintenance tips. Following these steps will maximize your investment.
