The primary function of welding shielding gases is to isolate the weld pool from the atmosphere, stabilize the arc, control penetration depth, and enhance overall weld quality. Conversely, select...
Welding current, voltage and welding speed are the main energy parameters that determine weld size.
1. Welding current
When the welding current increases (other conditions remain unchanged), the pe...
Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
“Welding” includes many different processes and systems.
MIG (Metal Inert Gas) welding involves the use of spools and MIG welding guns. This welding process is very good for both steel ...
Ⅰ. Start up
1. Turn on the power switch on the front panel and set the power switch to the “ON” position. The power light is on. The fan inside the machine starts to spin.
