25kVA Spot Welder Pedal Operated 380-700mm Arms Adjustment
- Simple, fast setup and operation, with easy adjustment
- 220 or 440V – dual-voltage welder works from 208-480, anywhere in your plant
- Arms easily slide in and out for small and large parts
- Access hard-to-reach welds with built-in angle / straight tip holders
- Easy-to-program weld controls
Features
- TE101 control, mounted on the front of the machine, allows the operator to view data while welding.
- Air pressure gauge, regulator knob, and speed controls are mounted at the top of the machine for easy monitoring and adjustment.
- Water-cooled transformer, arms, and electrodes. Epoxy resin-coated transformer for maximum protection.
- Adjustable electrode stroke enables access to a greater range of parts.
- Chromium-copper electrode holders are designed for long life and heavy-duty service. It may be mounted at 12° and 90° positions in the arm. Optional Universal-Style arms are available exclusively from WSI for 1″ diameter electrode holders, and for mounting the electrode holders at 30° and 90°.
- Adjustable throat depth enables maximum flexibility.
- Ergonomic frame for long-term operation in production environments.
- WSI exclusive standard low-profile lower holder enables accessing parts as small as 3″ diameter.
- Single foot pedal (standard). Additional foot pedal (optional part #73070) on base allows mounting both foot pedals on a joint base.
- PINCH POINT SAFETY OPTION: WSI-supplied TECNA rocker arm spot welders can be available with UNITROL Soft Touch Safety for pinch point protection.
