Binzel MMA to TIG Adaptor - Large plug to screw in connector with quick connect gas connection
Many MMA inverters boast TIG function but often lack some of the connections to get your torch working. These adaptors give you the perfect entry into the world of TIG welding and many TIG welding machines also use these connection pieces so it will essentially be the best bit of kit you can buy for very little cost.
This particular item is for the larger type sockets - 35mm+ for comparison picture 5 is the much smaller socket type (10-25).
As mentioned in the title, gas connection is a quick connector type and only suitable for machines with this type of fitting. Most machines have a screw on connection.
