3. Welding time is about 50% less compared to the normal electrode welding.
4. The learning time for the operator is very short.
5. Minimum waste of welding material.
6. Most important, this process allows to complete the welding more quickly and efficiently..
7. Less heat, less distortion.
8. Possible to weld thin materials.
PREPARATION FOR WELDING
1. Connect the welding machine to the 120V,
60 Hz line.
2. Connect the ground cable to the workpiece
(see Figure 3). Make sure that the contact
is good.
3. Make sure that the wire-feeding roll is cor-
rectly positioned (groove matching the
wire diameter). Note that each roll has two
grooves. One is marked “.035”/0.9 mm”
and the other is marked “.030”/0.8 mm.”
WELDING PROCEDURES
1. Your welding power source has two 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. The thickness of the material determines the wire speed.
REPLACEMENT OF THE WIRE SPOOL
The welding power source is supplied with a mini wire spool of of flux cored 0.035” diameter wire. When the
wire spool is finished it can be replaced with a wire spool of 2 lbs.
