OVERVIEW

Genuine Arcair 34Z50 Screw for K4000 Valve & Lever Assembly

Maintain the reliability and performance of your carbon arc gouging equipment with the Arcair 34Z50 Screw. This specific fastener is a critical replacement component designed exclusively for the K4000 (K-4000) Angle-Arc Gouging Torch. As a genuine OEM part manufactured by Arcair (an ESAB brand), it guarantees the precise thread pitch, length, and material strength required to securely hold the valve and lever mechanism in place.

In the demanding environment of heavy industrial gouging, torches are subjected to extreme heat, vibration, and mechanical stress. The valve and lever assembly is the control center for the high-pressure air stream that clears away molten metal. If the securing screw becomes loose, stripped, or lost during maintenance, the lever may fail to engage the air valve correctly, leading to inefficient gouging or safety hazards. The 34Z50 screw restores the structural integrity of this assembly, ensuring the lever pivots smoothly and the valve actuates with precision.

Professional welders and fabricators understand that using non-standard hardware in high-amperage torches can lead to premature failure. This screw is built to withstand the rigors of daily shop use. Whether you are performing a complete rebuild of your K4000 torch or simply replacing a lost fastener, this part ensures your equipment returns to factory specifications. It is an essential item to keep in your preventative maintenance kit to minimize downtime.

This screw is engineered specifically for the Arcair K4000 series of manual gouging torches. It fits into the valve body assembly to secure the operating lever. Please consult your torch's exploded view diagram or parts list to confirm the location (Item 34Z50) before installation.

FAQ

The 34Z50 screw is designed specifically for the Arcair K4000 (and K-4000) Angle-Arc Carbon Arc Gouging Torch.

This screw is part of the valve and lever assembly. It typically secures the lever mechanism to the torch body or valve block.

Yes, this is a genuine OEM replacement part manufactured by Arcair (ESAB), ensuring perfect compatibility and quality.

It is not recommended. The 34Z50 has specific thread pitch and material properties designed to withstand the heat and stress of gouging without damaging the torch body.

Typically, only one screw of this specific part number is required for the valve/lever assembly, but always check your specific torch diagram.

It is made of industrial-grade metal (steel or alloy) designed to resist the thermal and mechanical stresses associated with carbon arc gouging.

No, this SKU (34Z50) is for the screw only. The lever and other valve components are sold separately.

A loose lever often indicates that the securing screw (like the 34Z50) has backed out or the pivot point is worn. Checking and tightening or replacing this screw is a good first step.
