Question 1: How to change the welding wire for secondary welding? Feed the wire first, and cut off the welding wire from the gun side and the spindle muzzle.

Loosen the wire feeding pinch wheel, rotate the welding wire reel manually, and wind the welding wire onto the reel.

Clean up the wire feeder by the way.

Question 2: Where should the welding wire be changed from 1.0 to 1.2? You don't even ask how big the welder is?

Machines above 350 can only use 1.2 solid-core welding wire.

The machine of 3 15 is just right.

Below 300, it is recommended not to use it. Long welders can't stand it.

Wire feeding wheel (with teeth), wire feeding hose, conductive nozzle.

Question 3: Installation method of welding wire for secondary welding. Kneel and beg. The wire feeder is similar. First put the welding wire into the black handle, then put the welding wire into the small hole and press down the two wire feeding gears. Finally, the welding wire comes out of the small hole on the left,,, and it will be fine. The welding torch is connected to the far left.

Question 4: how to install the welding wire for gas shielded welding in the quiet brewing, but no one cares. /kloc-at 0/4: 28, a disaster fell from the sky at this terrible moment. The 8.0 earthquake centered on Wenchuan, Sichuan swallowed people's beautiful dreams. The earthquake destroyed people's homes and affected many provinces, cities and regions. Sudden power failure, traffic paralysis, mountain collapse, river flooding, people in the disaster area fell into it. Wenchuan, a little-known place on the map and rarely talked about by people, instantly became the focus of attention at home and abroad, that is, at that time, people carried forward the spirit of great love and extended a helping hand to the people in the disaster area. The State Council immediately issued an order to send domestic search and rescue elites to the disaster area, with the slogan of "Unity is strength, earthquake relief" and the main goal of "Time is life, and disaster is order" as a race against time.

Question 5: The second welding master asked how to change the second welding gas cylinder. Which screw should I remove? How to change welding wire? After the cylinder pressure relief valve is removed, the interface can be installed on a new cylinder. Of course, the gas cylinder valve should be opened before use. When replacing the welding wire, remove the welding wire coil and install a new welding wire coil. The welding wire should pass through the godet wheel, and the wire feeder should have a drive feed button to drive the welding wire in and out of the godet tube.

Question 6: How to install the second protective welding wire when it is used up? You can do it the other way around. Protective welding wire can be used for argon arc welding, but it cannot be used for argon arc welding. First of all, although your welding wire is disc-shaped, it is a problem whether it can be installed in the wire feeding tray. Secondly, the diameter of argon arc welding wire is larger than that used for gas shielded welding and does not match. Generally, the maximum diameter of gas shielded welding wire is 1.6mm, but you can consider submerged arc welding, which is larger.

Question 7: Do you need to remove the gun nozzle and the conductive nozzle to change the welding wire? The contact nozzle needs to be replaced according to the thickness of welding wire. If the process is good, the contact nozzle can be one step larger than the welding wire. The gun mouth doesn't care

Question 8: What if the welding wire in the welding nozzle is broken? Just remove the sheath and the contact nozzle, feed the wire and reinstall it. If it is burned together, only the welding nozzle can be replaced.

Question 9: How to take out the welding wire stuck in the gun, take off the contact nozzle, and then start the machine to feed the wire manually. Cut the welding wire from the protruding welding wire with needle-nosed pliers. Replace a new contact nozzle.
