Fig. 4. ARC FORCE function
3.3 ANTI ‐ STICK FUNCTION
During initial arc striking, the electrode can stick or be tacked to the work piece,
first leading to overheating and eventually to damage of the electrode.
If the electrode has stuck to the work piece, the machine reduces arc current
within 0.6...0.8 s. This function helps the welding operator to separate (detach)
the electrode from the work piece without risk to burn his eyes with accidental arc
striking. Once the electrode is detached from the work piece, the process of
welding can be readily resumed.
4. ATTENDANCE AND TECHNICAL MAINTENANCE
ATTENTION: Before opening the machine, switch it off and disconnect the
mains plug. Wait until internal circuits of the machine
de‐energize (about 5
minutes), and only then proceed with other actions. When leaving the
machine, install a restrictive plate which prohibits switching the machine on.
In order to ensure proper operation of the machine for many years, adhere to
several rules:
-
conduct inspection in accordance with safety practices within the established
time intervals (see "Safety rules" chapter);
-
if the machine is subject to heavy use, it is recommended to purge it with dry
compressed air once per six months. Attention: If the machine is purged from a
very short distance, electronic components may be damaged;
if the machine is very dust
‐ laden, clean channels of the cooling system manually.
