300547 - Syncrowave 250/350 Sequencer Module Kit

Take Full Control of Your TIG Welds

If you are running a Miller Syncrowave 250 DX or 350 LX, you know these machines are workhorses. But sometimes, standard pedal control isn't enough for those perfect, code-quality finishes. Enter the Miller 300547 Sequencer Module Field Kit. This isn't just a fancy add-on; it's a tool that solves the most annoying problems in TIG welding: hard starts and crater cracks. By installing this module, you gain the ability to automate the beginning and end of your weld cycle, letting you focus entirely on your torch hand and filler metal manipulation.

Why do you need a sequencer? Imagine welding thin gauge aluminum. If you hit it with full amperage instantly, you might blow a hole. With this module, you can set a soft starting current to establish the arc gently. Conversely, if you are on thick plate, you can set a "hot start" to get the puddle wet immediately. The real magic, however, happens at the end of the weld. The Final Slope feature automatically ramps down your amperage over a set time, allowing the puddle to close up slowly. This eliminates the dreaded "fisheye" or crater crack at the end of your bead, saving you from having to go back and fix stops.

The kit also includes a built-in Spot Timer. If you are doing a lot of fit-up work or sheet metal fabrication, this feature is a lifesaver. It allows you to set a specific time for the arc to be on, ensuring every single tack weld is exactly the same size and penetration. No more guessing, no more burn-throughs on tacks. This is a genuine Miller field kit, meaning it is designed to fit your machine perfectly and withstand the shop environment. Upgrade your Syncrowave today and stop fighting your arc starts and stops.

• Eliminate Crater Cracks: Automate your amperage ramp-down for perfect stops every time.
• Consistent Tacks: Use the spot timer for uniform tack welds on sheet metal.
• Custom Starts: Dial in hot or soft starts depending on your material thickness.
• Easy Install: Designed specifically for the Syncrowave 250 DX and 350 LX.
