Input:
Question: is there a change over switch when you change from 220 to 110?
Document: works ok once it's running but when you first turn it on it won't work and you need to shut it off and restart it . the torch cable is good and long but the ground cable is only 9' so you need to make up jumper or add to it if you will be working away from the bench . The torch tips are the same as the ones some of the small Hobarts and others use so you can get them local.
a big job for such a small machine but it did just fine. I have had this now for a little less than 90 days and had no problems. and would I recommend one to a small shop
You need dry, clean, oil free compressed air also. Don't bother with those self contained plasma cutters who have the air compressor built in, they work for thin stuff only, like maybe up to 18 or 20 gauge.This Forcecut 40D is rated at 40 amps output and I have used it to cut 1/2 inch steel without a problem. Does a good job on rusted metal, you need to grind a clean spot for the ground clamp.
Yes I would buy it again, great for a hobby guy or semi-pro metal worker! !
When I received the 40d the consumable starter kit was not there. Longevity support was great and Amazon fixed the problem within 1 hour. This is my first plasma cutter so it took some time to make decent cuts in 1/4&#34; 304 stainless. Too bad the settings information has to come from your own research. I would recommend buying a torch guide. It will save you money on consumables as a novice. I am very happy with this unit.
We do not blame Amazon....Longevity is the company that is to blame, sending us not once, but twice, a unit that was used! It is too late to ask Amazon for a refund, but we used AMEX to pay for the product and we will dispute the charge.
Was a little apprehensive at first, after all this is a Chinese made Plasma cutter. This is my third one, first was a Hypertherm  Made in USA and it worked great. Sold it when I sold my CNC plasma cutting machine it was attached too. Cutter #2 was a Eastwood, good plasma cutter but it was not pilot arc, had problems when cutting rusty metal.
This plasma cutter is awesome! Cuts through metal like butter. It is very portable and the dual voltage feature makes it functional just about anywhere. Longevity has great products with best in industry warranties! I own a few of the Longevity products and am very happy with the quality and performance. I recommend Longevity as your sole source for all your welding and cutting needs!
This machine is great! I used it for a restoration project. It cuts new metal but what is great is that it works on rusty old metal as well. Highly recommended!
This is an inexpensive plasma cutter and should not be expected to do what commercial units do. It is light weight and easy to use. You must have an air compressor to use with this unit. It cut right out of the box so I cannot complain about that. But the &#34;Consumables&#34;, the tips and the inner parts, get contaminated very quickly and have to be replaced or the unit will not work.
Answer: no
