Correct?
3.3.6
- In TIG, arc unstable, welding irregular.
NOTE
In TIG, the welding quality may not be acceptable due to current instability. In this case we
recommend switching to MMA operation, and performing welding tests.
WELDING QUALITY TEST IN MMA.
q
Power source in MMA, welding tests = good welding quality.
YES
NO
♦
Perform the “open circuit operation” test (par. 3.3.4) and “operation on resistive
load” (par. 3.3.5).
♦
Replace the power board (15).
♦
Check the condition of the torch and electrode. If necessary, sharpen the tip of the electrode.
♦
Check the presence and continuity of the gas flow at the torch output.
♦
Check the condition of the gas valve on the torch.
