K334 - Lincoln NA-5 Start/Crater Timer Control

Enhance Your NA-5 Control System

Upgrade your automatic welding setup with the Lincoln Electric Start or Crater Module - K334. Designed specifically for the industry-standard NA-5 Control, this module is the key to achieving professional, code-quality welds in automated applications. Whether you are struggling with inconsistent arc starts or dealing with crater cracks at the end of your runs, this module provides the control you need to solve those problems effectively.

Why You Need This Module

Automated welding demands consistency. However, the beginning and end of a weld are the most unstable parts of the process. The K334 allows you to set a custom Wire Feed Speed and Voltage for a duration of up to 10 seconds.

• Smoother Starts: Set higher parameters to blast through surface contaminants or lower parameters for a soft start, ensuring the arc establishes cleanly every time.
• Solid Stops: Use the module to fill the crater at the end of the weld. By maintaining the arc for a few seconds at adjusted settings, you add enough filler metal to prevent the crater from cracking as it cools.

Installation and Usage

The Lincoln K334 is straightforward to install and integrates directly with your existing NA-5 equipment. It is a robust piece of equipment built to withstand industrial environments. Please Note: This item is sold as a single module that can perform either the start function or the crater function. If your welding procedure specification (WPS) requires both a controlled start and a controlled crater fill, you will need to order and install two of these modules. Don't let start/stop defects compromise your production schedule—invest in the precision control of genuine Lincoln Electric accessories.
