So far so good, be aware it draws just over 15 amps when running so a 20amp circuit is a must. Surprised it doesn't come with a 20amp plug. The power cord is right at 4 feet long and does seem to be 14awg as it states but I swapped it for a different one I had from a server rack that was a bit longer and I know is good quality. I've melted a little over 10# of copper with it so far, two different days / batches. I did notice on the second run a bright flash Everytime the contactor drops out when it gets to temperature so I'll post an update if it fails on me (contactors normally rc a bit opening under load and for the price I didn't expect solid state controls) solid state relays are cheap and I may just upgrade it before I need to, but for now I'll just keep melting stuff. 1150c is the highest temp you can set it to, but that should be plenty for the metals it lists, I been pouring copper bars at 1100 and it does it decently fast, while pulling nearly 2kw of power.

Lets Start with the Poor As commonly mentioned the stickers are not meant to be left on, and the company name plate comes off easily as it is clearly meant to be rebadged by many sellers. The paint on the lid is appearing to show heat stress and flaking after the first two uses. The gloves are far thicker and heat resistant than anything I owned before, but not designed to protect you from much more than a brush with the hot crucible or the ingot cast block. It feels a little slow for copper as the max temp for copper is right about the top temp of this furnace but aluminum feels far faster. The Good It did have everything I needed to get started. The gloves did protect me from accidental contact with the crucible when poking at the slowly melting copper pieces. I mean the gambling on cheap Chinese products I guess its worth pointing out that it works at all. The temperature is slow to respond, but I thought the temp control was consistent. I do have some questions about heat distribution as my first pour left some copper parts in the crucible that I had to put back in and finish melting. That could simply be impatience or the material closer to the top didn't get the same heating level. Despite some paint discoloration after the first firing I see no indication that this won't be able to carry on for quite some time. I appreciated the attempt to make a pour spout in the crucible, but I still managed to spill when pouring so be careful. Now that I know this is possible I look forward to trying to cast some objects and possibly try to fill 3D prints.

UPDATE: I purchased this furnace, and it stopped working after just 60 days: 30 days after the Amazon return window. Other than that, it was an excellent melting furnace. I was angry and wrote the original review, below. This was the wrong of me as I never gave TOAUTO a chance to rectify the situation. So, after I calmed down, I contacted them to complain. TOAUTO immediately sent out a new unit. I haven't set-up the new furnace but intend to this weekend. The point is, TOAUTO stood behind their product and replaced it even after the Amazon replacement period had expired. The furnace is an excellent piece of equipment for its intended use and TOAUTO is an excellent company to work with. (And I was too quick and judgmental: shame on me for that.) This is a great company that sells a great piece of equipment at a great price. BUY WITH CONFIDENCE! ORIGINAL REVIEW: Worked fine until it decided to stop after only 2 months. Coincidentally, one month past the Amazon money-back guarantee. Absolute GARBAGE!

Over 2 years of ownership I have done a couple dozen smelts of small gold flakes and nuggets into either bars or coins. The electrical cord finally broke (or better said "fused" with my outdoor extension cord) on my last smelt thus rendering the system useless presently. Also it appears the internal casing has cracked in half. The Good: Easy to set-up, power up, set temp. A beginner can start melting metals within half an hour. The Bad: A beginner can start melting metals within half an hour. Doing pours for beginners is hairy. Graphite cylinders cool quickly giving you about 3 seconds to pour into small molds (that should be heated themselves btw.) After several uses system itself shows severe signs of internal wear, especially on heating element, interior casing and exterior of system...handle, bulb, and cap. Ideas: Consider making custom molds that can be inserted into furnace chamber directly to avoid pours. Consider including smelt "recipes" for flux...ie "50% volume of material in Chapman flux per full unit of material volume." The instruction booklet could do with a full revamp. Overall good deal in terms of price and utility, but beginners should think about ventilation, safety, and quality of furnace at all times. Full face protection and full length welding shirts have served me well. Two years of use might be the safe operational limit for this furnace. Noticeable decline in utility after each smelt until failure was reached on last smelt. If quality of furnace was improved and availability of replacement parts on Amazon was implemented this system as the potential to own the beginner niche and earn a 5-Star rating.

I bought one of these about 2 weeks ago and used it a couple of times. After two uses, the unit I had broken (the lid cracked and fell apart). I was a bit disappointed as I was worried about the quality of the item, however I figured sometimes a faulty unit can slip through quality control, so I reached out to the company and explained the situation. They immediately sent me out a replacement unit at no cost. I have used the replacement unit several times now, and it works great! Takes about 20 minutes to heat up (hot enough to melt copper), and once it is at temperature, it holds it just fine. I have melted copper, aluminum, brass, and nordic gold - all with great results. For the price, this is definitely worth it for beginners like myself.

Never worked, documentation was garbage or non existant. It was obviously burned out on delivery. Paint was missing and blackened on the outside of the main barrel. I was told i would only get a partial return and they would not replace it. I Purchased a replacement thermocouple as the troubleshooting guide called for and it still did not work.

I really liked how this kit came with everything I needed to get started melting aluminum. I've been wanting to try metal casting for awhile but was unsure of the learning curve and equipment required. I decided go give this kit a go as it looked like it had what I needed to get started. It came very well packaged. Operating it was as simple as taking it out and plugging it in. It automatically started heating to the set temperature. As advertised it takes about 30 to 40 minutes for it reach the highest temp but once it gets there it maintains it well even as I added room temperature aluminum. I melted down a bunch of cans that I was saving for recycle. The crucible is a smaller diameter than the cans so I had to cut and crush the cans to make them fit. It was easy to pour the molten metal with the supplied tongs. I never felt like I was going to lose control of the crucible or drop it. A full crucible fills about 2 of the included graphite molds. Once the mold cools the metal ingot easily falls right out. If you are just starting out in metal casting or want an easy to use furnace that doesn't use propane than I definitely recommend this one. It'll be great for smaller projects such as coins.
