Application Instructions:

Machine Connection: Ensure the welding machine is powered down and connect the holder to the welding cable using the integrated industrial-standard fasteners to ensure a permanent electrical fitment.
Electrode Insertion: Place the electrode through the “Electrode Through” port or into the grooved jaw at the desired 45° or 90° position for high-standard precision.
Stability Check: Verify that the jaw provides a secure, stable bond on the electrode before initiating the arc to maintain permanent structural safety.
Maintenance: Periodically inspect the jaws for weld splatter and ensure the cable connection remains tight for a high-standard, low-resistance electrical fitment.

Pro Tips:

Optimal Grip: For permanent structural safety, always seat the electrode firmly within the grooved positions to prevent arc wandering.
Contact Preservation: Keep the holder jaws clean of debris to ensure an industrial-standard stable arc and professional-tier results.
Integrated Safety: Always coordinate the use of welding equipment with professional-tier gloves and ocular protection to maintain a high-standard safety environment.
