If you need to weld 3/8" full-flanged stainless CD weld studs, and your current machine can't get there, the Tru-Weld TWi-375 is the right choice. This machine is the top model in the TW-i capacitor discharge stud welding series and offers the widest range of welding capabilities, from 14-gauge CD weld pins to 3/8" stainless CD welding studs.
It has a compact size of 14" × 10.5" × 11.5", consistent across the TW-i series. Weighing 23.4 lbs., it is the heaviest of the four models but still portable enough for use at job sites. Complete Stud Welding stocks the TWi-375 ready to ship alongside the full range of compatible TruWeld studs, capacitor discharge stud welding gun accessories, and CD stud welding equipment your setup requires. Let us know your application, and we'll get you configured correctly.
The TWi-375 is built for CD stud welding operations that run heavier fastener diameters without slowing down. Each feature on this machine addresses a real production requirement, from voltage management to operator comfort on extended welding cycles. This is what sets it apart on the floor.
The touchscreen stores factory-recommended voltage values for the full range of CD weld stud and capacitor discharge weld pin sizes. Operators pick the stud size on screen, and the unit loads the correct starting voltage. A metric stud mode handles international fastener sizes without manual conversion.
Voltage changes between capacitor discharge weld stud sizes go straight to the new set point without a full discharge cycle. On a machine rated for 3/8" studs, where every weld takes more energy, skipping that intermediate discharge step matters on a busy production run.
The TWi-375 runs on 110 or 220VAC input at 50/60Hz straight out of the box. No internal re-tapping, no stepping down transformers. One CD stud welding machine accommodates all power configurations at any facility or job site without hardware modifications.
Low-input voltage capacity lets this CD stud welding machine operate effectively on long extension cord runs, reaching areas where fixed outlets are inaccessible. It is particularly useful on large fabrication floors, open structural sites, and building interiors with limited power access.
Real-time indicators on the front panel show contact and trigger status. It allows operators to identify issues with hand tools and weld cables without needing to remove the unit from service or call for technical support.
Built-in indicators flag overtemperature, undervoltage, and duty-cycle limiter activation the moment they occur, keeping the capacitor bank and internal components protected from heat and unstable supply conditions before damage can happen.
Complete Stud Welding carries the Tru-Weld TWi-375 in stock with a full inventory of CD welding studs, capacitor discharge weld pins, CD stud welding gun components, and CD stud welding accessories. One call gets your order placed, configured, and out the door fast.
