Review on Mophorn Digital Inverter Welding Machine by Tom Duncan

Let me start by saying that I am specifically reviewing the Mophorn MIG Welder 200 Amp MIG TIG Arc Welder. Reading these reviews, it becomes clear that several different models are placed in a pile of reviews. This is probably normal as these models only differ in wattage rating, but I'm specifically talking about the 200 amp model. This rating only covers the MIG capabilities of this welder. This is a very cheap welder made in China. It cost $325 when I bought it less than a month ago, although I can see the price has gone up a few dollars since then. It's insanely cheap for a 220v 200 amp MIG welder. Even the cheapest US companies that sell slightly less powerful MIG welders (which are also all made in China) will cost a person at least $200 more, and the big boys will surely cost three times that or much more. However, one must be careful when someone buys such products that do not have established customer support and reputation behind their products. If you do decide to buy one, I would recommend that you actively use the welder during the 30 day return policy that Revain offers. If the welder does not break during this time, then it is unlikely to break in the near future. Don't rely on a company to fix you if it breaks at any point. With this in mind, I opened the box and immediately started using the welder in more severe conditions than an amateur welder like me would ever experience in real life. I wound up a 10 lb spool of .030mm wire, ripped out a 5" x 5" 3/4" thick mild steel sample, hooked up a large bottle of C 25 set at 20 cubic feet per hour and set out the way to town. I turned the welder on almost to the maximum (4 hours on the voltage regulator) hoping to see a small undercut as a penetration test. No problem! Beautiful beads with my simple, often practiced cursive E binding. After setting the movement speed, I began applying two-thirds of a pound of weld bead to the sample, continuously, back and forth, without pausing, wondering when I would reach duty cycle. I'm not a professional welder so I'm not used to lighting the wire like this. I feel like it took me 15 minutes of non-stop welding to run that much wire (I weighed the coupon before and after) but the machine never spattered, never shut down. When I was done the torch hose was quite hot but there were no problems. Since then I've run the car every night to make sure it starts and it always has. The wire feeds flawlessly and the arc is reliable and predictable. Before buying this welder, I was worried about consumables. My Eastwood MIG 135 welder uses Tweco Mini supplies which can be found at any supply store in the US and I keep a small supply of these supplies. This welder uses a smooth pressure nozzle torch as opposed to the threaded nozzle found on Tweco Mini units. If you have a drill press and drill vise, a 12mm (0.47") drill bit (https://www.amazon.com/gp/product/B082D9FLX6/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) the perfect drill hole .. out of one of those threaded bushings and allow for use with this welding torch.. I know most people don't want to mess around with a hack like this but if you use a welder for home projects it's probably available to a lot of people who have a will buy such a welder. I was also happy to learn that the Tweco contact tips I have are a perfect match for this welding torch. Use over several years MIG Welding Torch Pack of 18" https://www.amazon.com/gp/product/B07PH4P2XX/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 . They fit perfectly, and the nozzle opening is just under ½" (like those with supplied with the welding machine ex works t will) is a great all-purpose size. I wasted one of my old Tweco 3/8" sheet metal welding tips to save some gas, but that's just my opinion. The last thing to do if you're not a professional welder who's constantly welding is adjusting the voltage and wire feed speed on the welder is an important part of getting any job done right. Typically, novice welders include a chart that lists wire feed speed and voltage settings as a function of workpiece metal thickness and welding conditions with or without gas. This welding machine has no such table. I was pleased to find that on this machine, aligning the clock positions on the wire speed and tension knobs gives the ideal starting point for these settings when the solid wire diameter is .030 (at least with a C 25). I will never use anything other than .030 solid wire with a CO2/Argon mix with this machine.
