I'd been making different targets and having to order silhouettes online. Thought I'd try making my own so I bought a beginner plasma cutter. Reviews were kind on it. 110/220 I did get the 110 adapter but will need to make one to plug into the existing 220 in the garage. Harbor Freight had a welding cart that with a little modification I was able to put the wire feed welder underneath and the cutter on top. Added a outlet in the back so both could power off the cart. With a 25 foot power cord I can roll it outside my garage for cutting. I'll see how it goes. Hints or suggestions are welcome. I've used a gas cutting torch in the past this kind is new to me.

Well, I found out the 110 option trips breakers well. I had it turned down all the way and it still tripped a 15 amp garage breaker. Soooooo, off to Home Depot to make a 220 extension cord. 

Keep in mind this is my very first attempt and the metal was a little too thick for the setting I was forced to use.

Decided to try a simpler cut out.

I'll play with  it more when I get a 220 supply worked out. Kinda fun. 😀

More plasma cutting adventures. I did make a 220 extension cord so I could run it at a higher amp. Worked much better. Still getting the hang of it but I like it much more than a gas torch.

My son loves to get a crow in his sights so I made this for him. I like the white because you can see where the pellet hits.

The mount bar is removable on the base and bird for compact transport.

@pluric

Do you have a pilot arc or scratch type plasma cutter?

Pilot Arc. It's a Lotos 110/220 volt. Works much better on 220.

Nice machine and good work on the silhouettes, how thick is your metal and what PSI are you running it for 220V?

I just purchased a similar unit CUT50DF  110/220V with arc pilot to make some yard sculptures and will have to do a few silhouettes.

I also ordered a circle cutting guide for the unit.

The plasma swirl is not quite like cutting torches.

The gun can be angled differently to the work, no need to push heat ahead of your cut.

Keeping the kerf cleaned out requires proper gun angle, don't let the swirl erode the edges.

That last part keeps slipping my mind, and I try using it like a torch (except the torch wouldn't goober the work)

 

Try cutting something near the limits, get a good look at the arc's behavior when plunging or in a deep cut.

 

 

There you have it, the world according to John.
