Need help setting up plug to receptacle on new welder

admin

Hi all. So to start, this is my first decent welder in a long time, call it a start over. I took welding in college and did very well, but have done very little welding since with cheap 110 stick and mig welders.I'm going to be doing a lot of welding soon on my project car so I  purchased a new 220 welder, maybe not the best but got really great reviews from various sources. The welder is a LOTOS LTPDC2000D, combination TIG, Stick and plasma cutter, 110/220, 200A.I should mention for power/plug reasons, I'm USA based.The first problem I have before I even get a tank/argon/etc is getting power to it. It's set up with a 220 L6-30P plug which I have not seen before. Is this a new common type?I have an un-used 30A 4 prong dryer plug right inside the door from my garage to laundry area so I want to use that, avoid permits and stuff to install one in the garage. I'll eventually buy a really nice welder extension cable.So, baby steps, my first issue is making sure the plug on the welder itself is the most common so I can use it elsewhere down the line if I want. Is this the new norm (L6-30) or is what I think it is which is the 6-50P? (or something else perhaps)I tried looking at pictures of other 220 welders online but not many show the plug and those that do make it difficult to see.So, once I get a new plug on there if necessary, I'll worry about adapters or changing outlets.Also, figured I would see how far I can get on the 30A breaker, hopefully it's enough for what I need but I figure if not I will see if the wire gauge behind the receptacle is large enough and just change to a larger breaker if it is. How far do you think I might get with the existing 30?Thanks. Can't wait to start practicing!
Reply:Most newer 200 amp machines come with the NEMA 6-50 style plug. In your situation I would consider making an adapter pigtail. I just used a compatible dryer cord and a surface mount NEMA 6-50 receptacle.
Reply:Just for reference, below are screenshots of NEMA connectors, the tables taken from the sites below. I took two sections of the twistlock table since it was so long, containing 480-600v connectors you won't need info. about.https://www.stayonline.com/product-r...ence-chart.asphttps://www.americord.com/nema-charts---------------------------------------------

Reply:Are you sure it is an L6-30 ?the machine states that it is 110v/220v so I'm not sure how they are getting 110v if the power cord does not have a Neutral.If it is in fact an L6-30 you can certainly utilize the dryer receptacle's wiring:Turn off power.Remove dyer receptacle.Install L6-30 R : use the Black, Red and Green wires.

Reply:I found the manual online. Although it is a Dual Voltage machine one has to wire a 110v OR a 220v circuit.  It only uses 3-wires.So Imma guess it does have an L6-30 already installed.Specs: 45 A @ 220 V, 55 A @110 VDuty cycle @ 40°C (104°F)60% @ 200 A 100% @ 105 AEd Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge
