In one embodiment, a system is provided that includes a GFCI compatibility control configured to filter noise, improve symmetry between lines, or a combination thereof, when connecting a device to a GFCI-protected power source. In another embodiment a circuit for a torch power unit is provided that includes an inductor comprising a first coil and a second coil, wherein the total inductance for the first coil is substantially the same as the total inductance for the second coil, and a plurality of capacitors coupled to both the first and second coils. Another system is provided that includes a torch power unit. The torch power unit includes a compressor, a motor coupled to the compressor, and a GFCI compatibility control configured to filter noise, improve symmetry between lines, or a combination thereof, when connecting a device to a GFCI-protected power source.
