Just bought a Miller econotig that runs off 240volts. I am having trouble finding away to power it up. Searched the forums but cant find any info. I had a Miller 135 that ran off a house hold 120v outlet. I read i can use a dryer recepticle but where can i find a extention cable to power it. Lowes and Home Depot only have 6', i need about 12'. Any help would be great
