4-Step weld operation(Non initial)
● Suitable for welding long seam or medium thick plates
● The filling of the arc pit at the end of the welding can be achieved by welding with the
arc;
● During the welding process, when the continuous arc breaking occurs for more than
0.5 seconds, the self-locking is automatically released and the welding is completed.
● Enter the welding preparation state, and put the "2-step/4-step" switch of the welder
panel to "4-step". Press the torch switch and start to supply air and enter the pre-air supply
state. Waiting for a period of time, the welding voltage appears, and the slow wire feeding
starts to enter the arcing state. After the arc is successfully turned on, the wire feeding speed
becomes a normal speed and a welding current is formed. At this time, the torch switch can
be released and the welding enters a self-locking state. At the same time, the "welding
voltage adjustment knob" and "welding current adjustment knob" of the wire feeder must
be adjusted to achieve the best welding effect.
When welding to the end point, press the torch switch again to enter the arc
adjustment state; at this time, adjust the arcing voltage by adjusting the “arc voltage
adjustment knob” and “arc current adjustment knob” on the front panel of the welder. The
