RAF-300 - 300A Tong Style Stick Welding Stinger

Professional 300 Amp SMAW Electrode Holder

The RAF-300 Electrode Holder is a robust industrial accessory designed to meet the rigorous demands of Shielded Metal Arc Welding (SMAW). Engineered for a maximum current capacity of 300 Amperes, this holder ensures consistent electrical conductivity and arc stability, which are critical for producing high-quality welds. The unit utilizes high-grade copper alloy jaws that minimize resistance and heat buildup at the contact point, thereby extending the service life of the tool and improving energy efficiency.

Safety and durability are paramount in the design of the RAF-300. The body is fully insulated with a high-impact, heat-resistant fiberglass compound that protects the operator from accidental electrical contact and thermal transfer. The internal mechanism features a heavy-duty spring that exerts substantial clamping force, ensuring the electrode remains securely in place during manipulation. The jaws are grooved to accommodate electrodes at various angles—typically 45, 90, and 180 degrees—providing versatility for overhead, vertical, and flat welding positions.

Ergonomics play a significant role in the RAF-300's construction. The handle is contoured to fit comfortably in the hand, reducing grip fatigue during extended periods of use. The lever is positioned for easy actuation, allowing for rapid electrode changes even while wearing heavy welding gloves. Compatible with welding cables up to size 2/0, the connection point is secured via a robust set-screw mechanism (often including a shim) that prevents cable pull-out and ensures a low-resistance path for the welding current. This holder is an essential component for maintenance, repair, and fabrication operations requiring reliable stick welding performance.
