Installing gas bottle and testing gas flow
|
Handle gas bottles with care. There is a risk of injury if the gas bottle or the bottle valve is damaged! |
|
Always secure the gas bottle properly in an upright position to a special holder on the wall or on the welding equipment cart. Always keep the gas bottle valve closed when not welding. |
|
- If a cart with a gas bottle rack is used, install the gas bottle on the cart first, then make the connections.
- The maximum recommended size of the gas bottle to be installed on the T22M cart is 20 liters.
- Install the welding gun to the welding device before installing and testing the gas bottle.

Contact your local Kemppi dealer for choosing the gas and the equipment.
