• Turn the power source on and select the Stick function with Process Selection Button on the front panel
• Set the amperage with the Amp/WFS Adjustment (2)
• Strike the electrode against the workpiece to create an arc and hold the electrode steady to maintain the arc
• Hold the electrode slightly above the work, maintaining the arc while traveling at an even speed
• To finish the weld, break the arc by quickly snapping the electrode away from the workpiece
• Wait for the weld to cool and carefully chip away the slag to reveal the weld metal below.
Welding Current Guide
Choosing the correct current for a particular welding job is critical. If the welding current is too low, the user will experience difficulty
in striking and maintaining a stable arc. The electrode tends to stick to the workpiece, penetration is poor, and the weld ends up with
a rounded profile. If the current is too high, the problems include burning through the base metal, undercut, and excessive spatters.
The standard welding current for a particular job should be the maximum that won't burn through the base metal, Overheat the tung-
sten electrode, or leave spatters sticking to the workpiece surface.
The table shows current ranges generally recommended for a general purpose type E6013 electrode.
Set up for Stick Welding (SMAW)
• Check the electrode packaging to determine the recommended polarity and connect the electrode stringer and work clamp
to the POSITIVE (+) or NEGATIVE (-) SOCKETS accordingly
• Place the electrode into the electrode holder firmly
• Ensure the work clamp has good contact with the workpiece on a clean, bare metal surface free of rust, paint, or coating
Note: For Stick welding, DCEP means the electrode holder is connected to the positive socket while the work
clamp (workpiece) is connected to the negative socket.
However, various electrodes require a different polarity for optimum results. Please follow the electrode
manufacturer's recommendation on the correct polarity.
