Being able to operate the Maxstar 350 on single phase power provides additional flexibility and operation in areas that three phase is not available or allowed. | |||
| Size (H x W x D) in | 24.75 x 13.75 x 22.75 | 16.5 x 8.3 x 17.7 | 31 x 22 x 26 | Inverter technology provides more power than previous models in a smaller package at a fraction of their weight. | |||
| Weight | 135lb (61kg) | 52.9lb (24kg) | 397lb (180kg) | The Maxstar is an industrial grade machine that is built with heavy duty components and is still portable at 110 lbs. | |||
| Power Management | Auto-Line Any Voltage 208-575VAC Any Frequency 50-60Hz Single Phase or Three Phase |
Smart Logic 230 or 460 Any Frequency 50/60Hz Single Phase or Three Phase |
Manual Link 208/230/460 Model Specific 50 or 60Hz Single Phase Only |
Auto-Line allows for any input voltage hookup (208-575 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power. | |||
| Input Power @ 300 Amps *Denotes Single Phase |

The Maxstar consumes less power than conventional technology, provides more amperage & can be operated on 3-Phase. The result is reduced power costs and less installation costs when 3-Phase is used. | |||
| Open Circuit Voltage | Low OCV=10-15 Normal OCV=75 |
OCV=69 | Normal OCV=80 | The Maxstar OCV is selectable (low/normal) for some industry safety standards that require low OCV. | |||
| 120 Volt Auxiliary Power | 15A Duplex Receptacle | No | 15A Duplex Receptacle | 120 volt power available on all Maxstar 350 models. Power for coolers and small tools. | |||
| Last Procedure Recall | Yes | No | No | Maintains the established parameters in each memory, for all processes. Accurate and consistent setting for each job that you have. | |||
| Program Memory | 9 | 5 | No | Store up to 9 programs for each process. Displayed digitally. | |||
| Meters | Alpha-Numeric Dual Digital Amps & Volts | (1) Digital Amperage | (1) Digital Volts or Amps | The Maxstar 350 is equipped with 4 digit, 14 segment meters. Parameter settings are more clearly identified/understood because the meters spell out what you are setting. | |||
| Diagnostics | Yes | Yes | No | Meter displays of the Maxstar 350 spell out most errors and provide a better road map of the problem. | |||
| Auto Remote Sense | Yes | No | No | Senses when a remote control is plugged into the machine and eliminates the need to have a manual switch configured in the proper position to operate. This feature makes the machine easier to set. | |||
TIG Features |
|||||||
| Lift Arc Starts | Yes | Yes | No | Controlled contact arc ignition lets you start the arc in DC TIG without the use of High Frequency. | |||
| High Frequency | Start Only | Yes | Start (DC) | Because HF is only on to start the arc, it does not create HF interference issues in building/facilities. | |||
| Pulser Control | Yes, Digital, Complete | Yes | Yes, Non Digital, Complete | The pulsing feature is standard on the Maxstar 350 and has expanded parameter ranges for more control. | |||
| Max Pulse Frequency | DC=5,000 PPS | DC=500 PPS | DC=20 PPS | Pulsing at high speeds between a high PEAK and a
low background amperage can constrict and focus the
arc - which can reduce weld width and increase travel speeds. |
|||
| Sequencer | Yes, Digital, Complete | Yes, Digital, Complete | Down-Slope Only | The standard weld sequence feature allows the power source to control the entire weld cycle from start to finish. | |||
| Preflow | Yes, Digital | Yes, Digital | Internal Dip Switches Control 2 Settings |
Digital control provides consistent preflow times. | |||
| Postflow | Yes, Digital, Auto-Postflow or Adjustable | Yes, Digital | Yes, Non Digital | 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 the tungsten and prevents porosity. | |||
| Spot/Weld Timer | Yes, Digital (0-999 Sec.) =16 Min., 36 Sec. |
Yes, Digital (0-5 Sec.) |
No | The Maxstar 350 spot timer length of time is extended to 999 seconds. It also works with the sequence feature and can be used to automate timed welds. | |||
Advanced TIG Features |
|||||||
| Programmable Arc Starts | Amperage, Time, Polarity | Amperage | Output Start Control | Optimize HF arc starts for the application - program specific. Set start amps & time based on electrode diameter, material thickness & shielding gas. | |||
| Trigger Control | Standard Remote, 2T, 3T, 4T, 4TL, 4TE |
2T and 4T | Standard Remote, 2T | A variety of trigger methods can be selected to step thru the weld sequence. Choose the trigger that best fits the application and style of remote control. | |||
| Arc Timer/Counter | Hours, Minutes, and Cycle Counter | No | No | Can be used for preventative maintenance as well as weld cycle time for accurate costing purposes. | |||
Stick Features |
|||||||
| (Stick) DIG | Yes, Digital | Yes | Internal Dip Switches Control 2 Settings |
Tailored arc control (DIG) Allows the arc characteristic to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010. DIG is active in DC stick welding. | |||
| (Stick) Hot Start | Yes, Adaptive | Yes | Internal Dip Switches Control 2 Settings |
Adaptive control that provides positive arc starts without sticking. | |||
