2. IMPORTANT Make sure that the polarity of torch and ground cable is correctly set. For gasless welding, the ground cable must be connected to the positive ter- minal (+), while the torch must be connected to the neg- ative terminal (-) (see Figure 4).

3.Connect the ground cable to the workpiece. Make sure that the contact is good.

4.Make sure that the wire-feeding roll is correctly posi- tioned (groove matching the wire diameter). Note that each roll has two grooves. One is marked “.023”/0.6 mm” and the other is marked “.030”/0.8 mm.”

5.This unit comes with a preset regulator so there is no need to adjust the gas flow.

WELDING PROCEDURES

1.Your welding power source has four positions for the regulation of the current in the various conditions. The choice of the position for the welding is determined by the thickness of the material to weld.

2.Refer to Table 1 for the adjustment of the power source.
