Just bought a mishto generator 4.8/4kva .wont run a caravan aircon.Whereas a Yamaha 2.4 Iva will..The Mishto. Stalls dead .What is wrong.

SOURCE: mishto ct 312 plasma cutter wont cut

not only earth problem, change electrode, nozzle and cathode

SOURCE: Mishto plasma cutter and tig not working, there's no arc across the points, there was a good arc when it was working.

check fuse, or other loose connection

SOURCE: is the mishto 300 welder anygood

Light duty 60% duty cycle.

SOURCE: i brought a mishto cb330 car battery charger its not charging my car battery its been on charge all nite the green indicator on the battery has not lit up yet or am i using it wrong.

possibly
the charger leads ( red and black) have to be connect correctly
red to the positive+ terminal of the battery and black to the negative - to the battery
if they were wrong , you may have to replace a fuse in the battery charger
