| Output Range | 5-425 Amps | 5-400 Amps | 5-425 Amps | Wide amperage range of output for significant flexibility. | |||
| Output Rating | 350A & 60% | 300A & 60% | 350A & 60% | 350 Amps for more deposition and more carbon arc gouging capacity. | |||
| Input Current at 350 Amp output | 17.8 Amps 460 VAC |
22.5 Amps 460 VAC |
23 Amps 460 VAC |
XMT-350 takes 25% less current! This enables smaller fuses/breakers. More arcs can operate on the limited primary current typical of construction sites. | |||
| Auto-Line™ | Yes | Auto-Link | No | This Miller patented circuit enables any primary voltage (208-575 VAC) to power unit. Perfect for dirty or unreliable primary found in field applications. No manual linking, no moving parts! | |||
| Auto-Link® | Auto-Line | Yes | No | This Miller exclusive circuit automatically links the power source to the primary voltage. 208/230 or 460 VAC, 460 or 575 VAC, single or 3 phase) No need for manual linking, reduces chance for errors. | |||
| Power Efficiency | 87% | 85% | — | Miller XMT's have remarkable electrical efficiency, saving $ by reducing power consumption. | |||
| Low OCV Stick | Standard (internal selection) | No | — | A built-in, selectable feature, that reduces the Stick mode open-circuit voltage (OCV) to nearly 15 volts when the welding power source is not in use. Eliminates the need for add-on voltage reducers. | |||
| Weight | 80 lbs. CC/CV 70.5 lbs VS |
79.5 lbs. | 81 lbs. | XMT-350 VS is 10lbs lighter, easier to move at construction sites. | |||
| Control Receptacle | Yes (CC/CV) No (VS model) |
Yes | Yes (Fact.model) No (C model) |
Remote control is not possible with Lincoln's Construction or XMT-350 VS models since these units are not supplied with a control receptacle. | |||
| Wind-Tunnel Technology™ | Yes | Yes | Conductive shop dust tends to collect on internal components that block air flow | Protects electrical components and PC boards from contamination, significantly improving reliability by minimizing dirt buildup and maximizing cooling! | |||
| Fan-On-Demand™ | Yes | Yes | Fan latches "On" after unit is used, and stays on! | In dirty dusty environments, Fan-on-demand reduces amount of airborne contaminants pulled through the machine. Fan automatically turns off after unit is cool, saving electricity($). | |||
| Line Voltage Compensation | Yes 190-630 VAC Widest link-free primary range in the industry! |
Yes +/- 10% | Yes +/- 10% | XMT-350 can compensate for more input power fluxuation (dirty power), than any other welding power supply. | |||
| Meters | One Volt/One Amp | One Volt/One Amp | One Volt/One Amp | Large dual meters display both volt and amps for quick easy viewing by operator. | |||
| On/Off Switch | Front | Front | Front | Due to location of Lincoln switch, unit is very difficult to re-wire with recommended cord for single phase 208-230 VAC operation. | |||
| Adaptive Hot Start for Stick | Yes | Yes | Knob | Adaptive Hot Start automatically increases output amperage if needed, great start. | |||
| Control Cover Protection | Yes | Yes | Yes | Protects front controls from damage in rough conditions. | |||
| Primary Power Cord | Yes - 10ft. | Yes - 10ft. | Yes - 10ft. | Saves time in hooking up the primary cords. | |||
| Lift-arc TIG | Yes | Yes | Yes | Tungsten contamination-free TIG starting without the use of high frequency. | |||
| Self Diagnostics | Yes, Micro Controlled | Yes, Micro Controlled | Yes | Error message displays on meters for ease of diagnosing if problem occurs with output. | |||
| 115 VAC Auxiliary Power Option | Yes - 10 Amps CC/CV model only |
Yes - 10 Amps | Yes | 115V duplex receptacle gives you 10 amps of auxiliary power. | |||
| Process Selector Switch | Yes Large dial |
Yes Large dial |
Yes Push button |
Reduces the number of control setup combinations without reducing features. | |||
| Gas Valve Option | Yes | No | Yes | Conveniently provides gas valve for TIG welding. | |||
| Handles | Two on top | Two on top | 1 top & 1 mid front | Miller's handles are ergonomically placed. | |||
| 6010 Arc | Excellent | Excellent | Adequate | Arc outages with Lincoln products. | |||
| MIG Arc | Excellent | Excellent | Adequate | Miller units have enhanced low-end performance for stainless steel and thin-metal performance. | |||
| Warranty | True Blue 3 Year 5yr coverage on Power Rectifiers |
True Blue 3 Year 5yr coverage on Power Rectifiers |
3 Year | Service friendly, internal components are easy to access and cool, not excessively coated. | |||
