The Maxstar 350 has exceptional performance and is considered the finest DC TIG/Stick machine available that provides outstanding arc performance and product reliability. The DC TIG features an exceptionally smooth and precise arc and high-speed DC TIG pulse controls. The DC Stick features the tailored arc controls (DIG) and the Hot Start. Both come with Auto-Line, which allows for any input voltage hook-up (208-575 V) with no manual linking, providing convenience in any job setting. 120 V auxiliary power receptacle for cooling system or small tools. Program memory features 9 independent program memories that maintain/save your parameters. Programmable start parameters allow the operator to independently set starting conditions based upon process and memory selections (amperage and time). Superior TIG/Stick arc performance on all input voltages. Even on the difficult to run electrodes like E6010. HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination. Auto-Postflow calculates the length of postflow time based on the amperage setting. This eliminates the need to independently set the postflow time for different amperages. This feature preserves your tungsten and prevents porosity. And also features the Fan-On-Demand, Wind Tunnel Technology, and LVC Line Voltage Compensation technology from Miller.
Maxstar 350 provides the basic features that are required for most DC TIG or Stick welding applications.

Truck Freight Additional Information:
This product is too heavy/large to ship via the small package delivery services (e.g. UPS, FedEx) so it will be sent to you via truck freight. Truck freight is different than standard UPS, FedEx or US Mail in that you will be responsible for carrying the product from the back of the truck into your house (or wherever it's going).
The most important thing to remember about truck freight is that you MUST inspect the package at the time of delivery. If the box has any damage, or if there is any reason for you to be at all concerned about damage, please write "PRODUCT DAMAGED" clearly on the sheet that they ask you to sign. This simply insures that if there is any damage, it will be easy to take care of the problem.
If you are ordering a very large item, please keep in mind that you may need a couple of people to help unload it. Alternatively, most truck freight companies offer additional services to help you move items from the truck into your house. Once we email you the tracking information you can contact the shipper directly to inquire about additional services. You would be responsible for directly paying the truck freight carrier for any additional services.
