NOTE! The operator should set the functions that meet the welding requirements . If
the selections are incorrect, this may lead to problems such as an unstable arc,
spatter, or sticking of the electrode to the work piece.
Arc force: The arc force value should be determined according to electrode diameter,
current setting, and process requirements. With large arc force current, the metal transfers
quickly and the droplets don’t stick, but excessive force increases spatter; low arc force leads
to small spatter and good weld seam formation, but sometimes the arc is soft, or causes
droplets to stick. In particular, thick electrodes with low current welding require increased arc
force. Generally, the arc force is 0-40 when welding.
Hot start current: Stronger hot start current is conducive to arc start and reduces sticking
between the welding electrode and workpiece during arc start. Set to 30A by default.

During DC welding the heat on the positive and negative polarities of the welding arc is
different. When welding using DC power supply, there are DCEN and DCEP connections.
The DCEN connection refers to the welding electrode connected to the negative polarity of
the power supply and the workpiece connected to the positive polarity of the power supply. In
this mode the workpiece receives more heat, resulting in high temperature, deep penetration,
easy to weld through, suitable for welding thick parts. The DCEP connection refers to the
welding electrode connected to the positive polarity of the power supply and the workpiece
connected to the negative polarity of the power supply. In this mode the workpiece receives
less heat, resulting in low temperature, shallow pool, and less penetration. This is suitable for
welding thin parts.

NOTE! This unit has anti-stick function by default. In the welding process, if short
circuit occurs for 1s, it will automatically enter anti-stick function. This means the
welding current will automatically drop to 20A to allow the short circuit to be cleared.
