NAME EXPLANATION:
1. GAS PRE-FLOW:
Time of ahead gas sending as you prepare to welding.
2. STARTING AMP.:
starting current.
3. CURRENT UP SLOPE:
time slot for welding current increasing
4. WELDING AMP.:
Welding current in the constant current output estate.
5. PEAK AMP.:
the peak value current when pulse outputting.
6. PULSE WIDTN:
Time proportion of peak value current when pulse outputting, which controls
The welding line deep and realize entire position welding and sheet welding.
7. PULSE FREQ:
Working frequency when pulse outputting.
8. AC FREQ:
Output frequency of AC working.
9. CLEAN WIDTN:
the time proportion of minus direction current within one AC welding cycle.
10. CLEAN SCOPE:
the percentage of minus direction current scope adding when AC welding.
11. BASE AMP.:
the maintaining arc current when pulse outputting.
12. CURRENT DOWN SLOPE:
time slot for welding current decreasing.
13. FINAL AMP.:
the welding current before finishing welding
14. GAS POST-FLOW:
Gas extending time after welding is finished. It can protect the welding line
and the
15. 1#: "EASY/ STICK/ PULSE TIG/TIG/" button:
the indicator on position stands for current estate. EASY means automatic
welding and nothing can be adjusted except current; STICK means: MMA
welding; PULSE TIG means TIG welding with pulse function; TIG means the
common TIG welding.
