| Weld Processes | AC/DC/CC/CV | DC/CC/CV | Full Multi Process Machine | ||
| Rated Weld Output | 500A/40V/100% | 500A/40V/100% | Lincoln could not make rating with air on. | ||
| Welding Output | 40-750A DC, 20-450A TIG, 14-40V TIG, 20-750A AC |
30-575 DC, 40-300 Pipe, 20-250 TIG, 14-40V CV |
Miller has 23% more DC output, 33% more TIG output, 750A of AC output. The Lincoln does not have AC weld output. At 40C/104 degrees Lincoln’s DC output is only 475A and 44CFM air. | ||
| Air Compressor | 60 CFM @ 100 PSI 100% Duty Cycle |
60 CFM @ 100 PSI 100% Duty Cycle |
At 40C/104 degrees while welding the Lincoln’s air output is only 44 CFM @ 100 PSI. | ||
| Welding Ranges | 5 Ranges w/Fine Adjust in Each Overlapping Range | Single Range | Miller uses Mode switch, course range and fine adjust knob. Lincoln uses mode switch, output control, arc control and contactor control to control weld output. | ||
| Arc/Dig Control | Yes/Self Adjusting | Yes/Adjustable | Self adjusting is easier to setup. | ||
| Welding Meters | Yes/Analog | Yes/Digital | Similar | ||
| Polarity Switch | Optional | Not Available | Ease of set up and operation. | ||
| Remote Control | Standard | Standard | Same | ||
| Generator | AC Generator | AC Generator | The Miller design is enclosed and provides better cooling and protection. | ||
| AC While Welding | 5kW At All Times | Relative to Weld Output | Plenty of power for lights and grinders. | ||
| 3 Phase Aux Power | 20 kW | 20 kW | Same | ||
| 1 Phase Aux Power | 12 kW | 12 kW | Same | ||
| 120 Volt Receptacles | 20 Amp Duplex, Breaker | 20 Amp Duplex, Breaker | Same | ||
| 240 Volt Receptacles | 50 Amp, Breaker | 50 Amp, Breaker | Miller has two 240 V receptacles. | ||
| Generator Protection | H.F. Protected | Unknown | Better protection provides superior reliability. | ||
| Engine Choice | Deutz BF4M 2011 Turbo Charged Oil Cooled Diesel 64 HP @ 1800 RPM Idle Speed 1235 RPM |
Cummins/Komatsu B3.3, 4 Cylinder Water Cooled Diesel 56 HP @ 1800 RPM Idle Speed 1400 RPM |
More horse power and turbo charged for better performance at higher elevations, MSHA approved for underground mining. Lincoln is underpowered and struggles under heavy loads. | ||
| Auto Engine Shutdown | Oil Temp, Oil Pressure | Water Temp, Oil Pressure | Same | ||
| Automatic Idle | Standard | Standard | Lincoln has 2 solenoids/requires more maintenance. | ||
| Compressor Instrumentation | Air pressure gauge standard, w/ optional air filter service indicator | No air pressure gauge or air filter service indicator, has a over temp indicator light | Air pressure gauge and filter service indicator helps insure regular filter maintenance and helps diagnose air flow problems. | ||
| Remote Oil Drain Compressor | Yes | Yes | The Lincoln drain valve is very hard to get at and open when machine is hot. | ||
| Compressor Protection/Shutdowns | Over Temp, Low Oil, stops compressor rotations by opening the drive clutch | Over Temp, shuts down unloader valve and air output | The Lincoln compressor does not stop turning when over temp occurs or if compressor runs low on oil because it is gear drive directly from the engine. | ||
| Engine Gauges/Warning Lights | Fuel, Oil Temp, Oil Pressure, Battery, Voltmeter, Air Pressure Gauges,Hour Meter | Fuel, Water Temp, Oil Pressure Gauges/Engine Over Temp, Battery Charge, Indicator Lights, Hour Meter | The Lincoln does not have an air pressure gauge or any other indicator that the air compressor is operating correctly. | ||
| Electronics Protection | 1 circuit board enclosed in the vault | 5 circuit boards encased in RTV silicone rubber | Miller has proven that the Vault used in the Big Blue series is the most dependable circuit board in the industry with a 99% reliability rating. | ||
| Battery Charge Jump Start | Yes, 12/24v 800 amps | Yes, limited power in the machines battery 12v only | The Miller machine has a true battery charge/jump starting system. | ||
| Engine Service Side (Facing Weld Controls) | Right Side | Right Side | Same | ||
| Remote Oil Drain Engine | Yes | Yes | The Lincoln drain valve is hard to get at and open when engine is hot. | ||
| Fuel Tank | 25 gal/95 ltrs | 25 gal/95 ltrs | Same | ||
| Fuel Consumption at rated output 500A @ 40V, 60CFM @ 100PSI | 2.52 gal/hour-9.5 L/hour |
Actual: 3.1 gal/hour-11.7 L/hour Stated:2.46 gal/hour-9.3 L/hour |
Testing the Lincoln at 40°C temp. rating, actual fuel usage is 3.1 gal/hour-11.7 L /hour or 24% more fuel than the Miller. | ||
| Fuel Consumption at idle/no load | .37 gal/hour-1.9 ltrs/hour | .59 gal/hour-2.2 ltrs/hour | The Miller uses 37% less fuel at idle. This is due to not turning the compressor all the time and lower idle speed. | ||
| Sound Level | 103.9 Lwa Sound Power 79 dBa at 23 ft ( 7 m) | 109.1 Lwa Sound Power 84.2 dBa at 23 ft ( 7m ) |
While running 500 amps, 40 vdc with compressor on. Miller is much quieter! | ||
| Dimensions HxWxD | 43 x 28.5 x 67.5 in 1092 x 724 x 1715 mm | 50.8 x 32.7 x 63.1 in 1290 x 831 x 1603 m |
21% Smaller in size, Larger in performance. | ||
| Weight | 2185 lbs/1007 KG Gross wet weight | 1955 lbs/887 KG Gross wet weigh | The Miller is only 12% heavier, with more output and performance. | ||
