Plasma cutter arcs but will not cut.

[LONGEVITY]

Gumby,

If that machine is made by a factory I think it is made by, check inside for the High Frequency board and insure there is a good distance between the two points on the front left where the HF arc initiates.

Other things to try:

1. Turn down the PSI to say 35-60 at increments of 5.
2. Wire at 220v and see if the unit functions. Sometimes, the 110v is not enough to power these types of cutters.
3. Check the ground and make sure its connected.
4. Check to make sure there is nothing blocking the air inlet.

Hope these help. If not, give the company a call for a warranty claim or trobleshooting.

SICFabrications & Longevity,

Your help is greatly appreciated.

Before I can wire it to 220v I need to find the cable and plug to be able to do it.

You all have helped so very much and have given me some great suggestions.

I need some garage time to see I can put your suggestions to work.

Thanks
Gumby

The information you posted about the machine states that all you need for 220 is to replace the plug on the power cable.

The wire going into the machine is just standard 110 wiring with a 110v plug in.

I would assume if I cut it off to put a 220v plug on the end I would melt the wire off.

Thats why I think I need to find out what wire to use and a 220v plug to use in the garage.

My brother suggested I buy a RV 220v to 110v adapter,but I would think in doing so the machine would operate at 110v and not the desired 220v.

The wire going to the machine should be able to carry the maximum current the machine is rated for. Otherwise they couldn't sell it as that capacity. Keep in mind that the 50 amp on the leads doesn't equate to 50 amps on the input side. It's more likely that the current requirement on the input side is somewhere between 25 and 30 amps, probably closer to 25. According to the chart here American Wire Gauge table and AWG Electrical Current Load Limits with skin depth frequencies 14 gauge wire can carry up to 32 amps for chassis wiring and so it should handle the amperage on the input side of the cutter.

• Dual input voltage - functions with either 110v or 220v, single-phase power (U.S. 60 hz. or European 50 hz.) Standard U.S. 3-prong, 15-amp grounded, 110v plug is pre-installed. If you prefer to operate the unit with 220v power, simply install a new plug on the power cord to fit your receptacle. The machine will automatically detect the input voltage/frequency and adjust.

There is your answer in the machine description you posted.

Your machine is rated at 30 amp input. I would use GA wire to be on the safe side.

Yes you right is supost work n 110 volts but if don't touch the metal never get arc

hello KHK.
