What is a Contact Tube in Welding?

A contact tube is a system component that transfers current from the torch gun to a continuous electrode. This enables a welder to have a more consistent arc and helps prevent the electrode from becoming stuck in the puddle.

The contact tube also provides a path for the shielding gas to flow around the electrode and into the weld puddle. This gas helps to protect the weld from contamination and oxidation.

A contact tube is a key part of the welding process and helps to create strong, consistent welds. If you are having trouble with your welds, check your contact tube to make sure it is in good condition and properly installed.

Advantages of Contact Tube in Welding

Helps to create strong, consistent welds.
Protects the weld from contamination and oxidation.
Prevents the electrode from becoming stuck in the puddle.

Disadvantages of Contact Tube in Welding:

Can become corroded over time.
May need to be replaced periodically.

What is a stick-out in MIG welding?

Stick-out is the distance between the end of the electrode and the contact tip. It is important to maintain the correct stick-out in order to create a strong, consistent weld. Too much or too little stick-out can cause problems with the weld.

The best way to determine the correct stick-out for your welding project is to consult your welding manual or ask a professional welder. Stick-out is an important part of the welding process and should be carefully monitored to ensure optimal results.
