Gas hold welding can weld aluminum wire.
The method is to rotate the wire into a u-shaped wheel, wire hose into the teflon, the gun into water cooling.
Gas shielded welding refers to the method of carbon dioxide or argon shielded welding without welding rod or wire.CO2 welding efficiency is high, argon welding mainly welding aluminum, titanium, stainless steel and other materials.
The use of welding torch must first check the suction performance and air tightness, welding torch connecting parts, gas channel and control valve, etc., shall not be contaminated with grease.
Torch ignition, should first open the acetylene valve lit, then open the oxygen valve to regulate the flame;Turn off the fire, should first turn off acetylene, then turn off oxygen.Stop use, do not torch, hose and gas source permanent connection.
When using cutting torch, should clean the work surface of paint, rust layer, and can not work on the cement floor, in order to prevent rust water and cement in the case of high temperature splash injury.
In cutting torch ignition, ignition test should be done first, check whether the nozzle is installed.A ceasefire should be followed by acetylene and then oxygen.
