While TIG is typically only used on very thin metals, it has a wide range of applications for both hobbyists and professionals. AC/DC welders are ideal for multiple uses around the home such as pipework, joint work, and automotive repairs, making it an essential piece of kit for DIY enthusiasts.
Arc welding is the process of melting two metals together. It uses electricity to create intense heat which melts the two metals together in a molten pool, effectively making them one material. This is called welding fusion and is the reason welded structures are so strong.

CUT-55DS not ignite at 120V with recommended pressure and consumable, the led indicator flash @110v, it won't @220V. 1. Open the cover 2. Check this light in the PCB board, it will be on @110v/120v, it will not be on @220v. (it‘s for voltage doubling) 3. If no led light on, check the wire connection, there's a loose connection
So easy, pull it up and turn clockwise to make it from high to low, counterclockwise from low to high

Here is a small video about how to install the 10lb spool for 250A welder.
YesWelder PRO250 welder could aluminum welding. It could weld aluminum with 'OP' and 100% argon or Mix gas.   Things needed: 1.Graphene liner or Teflon liner for aluminum for the MIG torch  2.U type roller instead of normal V type roller inside the machine.  This video is step2 for change Graphene liner or Teflon liner into the gun torch
This is a video to tell you how to install the steel pipe back in the wire feeding part when the Graphene liner or Teflon liner for aluminum for the mig torch, is not  needed again. Note: Frequent removing and installing will make the welder work improperly.
