Using a TIG torch hand control will allow you the ability to easily control your welding while having the ability to adjust your TIG welder. The hand control wraps right around the TIG torch itself and allows you to control the welding process without having to use a foot torch control.
The hand control allows you to turn the TIG torch on and off all with just one hand. The same hand you are holding your TIG torch. This can be very beneficial where you have to work in a confined place where you cannot have access to foot control to turn your welding machine on and off while you are welding.
Like the foot control, the hand control allows you to adjust the amount of ampage that you are welding with. The control mechanism is either rotatory or linear to increase or decrease the total ampage.
