Tow/drive the jeep to a carwash bay, use the degreaser and let it soak a bit, then rinse with the hot high pressure spray, then repeat with Simple Green. The hot pressure washer is what does the work by melting and blasting off the grease and sludge.
I did this with my Camaro when I swapped...
With LIPO batteries and brushless motors, electric is now soo much better than nitro... faster, more powerful, longer runtime, lighter, simpler, cheaper, etc.
In a word, no.
If you had a 100ft extension and were to measure the input voltage at the welder while welding at full power you may notice that 10volts or so (of the 240v) are dropping in the resistance of the wiring. If you're using an inverter welder this won't effect welder output but it...
Maybe your buddy doesnt realize it's a 230v welder? if the voltage is doubled the current is halfed for the same wattage. Maybe his 30amp breaker is worn out and trips easily.
My mistake, I just checked my roll of 71m and it's .035". My Millermatic 175 runs it beautifully (C25 gas).
Well within sugested specs http://content.lincolnelectric.com/pdfs/products/literature/c3101.pdf
More heat, not necissarily "hotter" (think of 1 match vs 2 matches).
MIG welding being a constant voltage process, leaves the amperage dependant on the feed rate or deposition rate (wire speed). Cranking the wire speed requires the amperage (and therefore wattage) to increase since the machine...
For these little welders the .045" wires are usually flux cored (not solid metal). FCAW wires usually burn hotter and penetrate more because they run at DCEN polarity.
What are the thickness and rough dimensions of the parts to be welded?
I can TIG aluminum at work. If the parts are very thick MIG might be required.
My resume:
3.5" 16awg tubing butt welds
30 amps at 220v is probably more than the machine needs anyway. Also, you won't often be welding at full power with a 220v welder.
If the plug is different, just make an adapter.
