How to use WSE250 of Ling Rui aluminum welding machine? I'm a novice. I just bought a Ling Rui aluminum welder. I don't know how to use it without the instruction manual.

1, aluminum welder WSE250 function buttons and potentiometers are mainly used to control the functions of aluminum welder, such as DC argon arc welding iron, carbon steel and copper alloy, such as AC argon arc welding aluminum, magnesium alloy, zinc alloy and brass, while the welding function can weld iron, copper, aluminum, stainless steel and alloy steel.

2. The buttons of aluminum welding machine mainly include: panel/remote control, AC /DC, manual welding/argon arc welding, 2T/4T/ repeat, and then there is the function of low frequency/intermediate frequency/no pulse.

3. If welding aluminum alloy, adjust it to: open panel control, AC function, argon arc welding, 2T (normal), pulse off.

Buttons of aluminum welding machine mainly include: arc starting current, welding current/peak current, arc closing current, base current, pulse frequency, duty ratio, current ramp-up time, cleaning width, current ramp-down time and gas delay time.

4. Adjustment of welding aluminum alloy: start the starting current in 4T mode, adjust the welding current with welding current, adjust the 4T third gear current, base value, pulse frequency and duty ratio with closing current, and adjust the cleaning width to the middle position. These settings can basically meet the basic requirements of aluminum welding.

First, the characteristics of aluminum welding machine

Aluminum welding machine uses low-voltage and high-current electric energy to instantly convert electric energy into heat energy through arc, and uses high-purity argon as protective gas to avoid blowholes and impurities during welding. At the same time, both AC argon arc welding and MIG gas shielded welding have certain cathodic cleaning function, which can directly remove the oxide film on aluminum and aluminum alloys.

Because of its small size, simple operation, convenient use, high welding efficiency, good weld formation and deep penetration, aluminum and aluminum alloy plates can be completely welded to achieve high-quality bonding effect, and the welding strength is the same as that of the base material, so it is widely used in various fields of industry and life.

Aluminum welding machine will produce arc light in the process of use, which contains infrared rays and ultraviolet rays, and also produces harmful substances such as metal vapor and smoke. The tungsten rod in TIG welding contains a small amount of radioactive elements, so adequate protective measures must be taken. In addition, argon, as a protective gas, is not suitable for operation in windy welding site.
