Welding SMAW Process
DIGISTEEL 250C / PRO, DIGISTEEL 320C / PRO,
DIGISTEEL 380C PRO, DIGISTEEL 450C PRO does
not include the electrode holder with lead necessary for
SMAW welding, but the one can be purchased
separately (see "Accessories" chapter).
Procedure of begin welding of SMAW process:
Procedure of begin welding of SMAW process:

First turn the machine off.

Determine the electrode polarity for the electrode to be
used. Consult the electrode data for this information.

Depending on the polarity of using electrode, connect
the work lead [19] and the electrode holder with lead to
output socket [2] or [3] and lock them. See the Table 22


Connect the work lead to the welding piece with the
work clamp.

Install the proper electrode in the electrode holder.

Turn the machine on.

Set the SMAW welding program.

Set the welding parameters.

The welding machine is now ready to weld

By applying the principle of occupational health and
safety at welding, welding can be begun.
For SMAW process user can set:

Welding Current

Switch on / switch off the output voltage on the output
lead.

Wave Control:

Arc Force

Hot Start

Loading the Electrode Wire
Depending on the type of wire spool it can be installed
on the wire spool support without adapter or installed
with use applicable adapter that must be purchased
separately (see "Accessories" chapter).
WARNING
Turn the input power OFF at the welding power source
before installation or changing a wire spool.

Turn the input power OFF.

Open the side panel of the machine.

Unscrew the Locking Nut [24] and remove it from the
Spindle.
 Place the spool [23] on the Spindle [24] making certain
the Spindle Brake Pin is put in the hole in back side of
spool.
If using adapter (see "Accessories" chapter), place it
on the spindle [24] making certain the spindle brake
pin is put in the hole in back side of the adapter.
WARNING
Position the spool so that it will rotate in the same
direction as wire feed and electrode wire should feed from
the bottom side of the spool.

Install the locking nut [24]. Make sure that the locking
nut is tightened.
Adjustments of Brake Torque of Sleeve
To avoid spontaneous unrolling of the welding wire the
sleeve is fitted with a brake.
Adjustment is carried by rotation of its screw M10, which
is placed inside of the sleeve frame after unscrewing the
brake locking nut.

54. Adjusting Screw M10.
55. Pressing Spring.
Turning the M10 screw clockwise increases the spring
tension and increase the brake torque
Turning the M10 screw anticlockwise decreases the
spring tension and decrease the brake torque.
After finishing of adjustment, you should screw brake
locking nut again.
