13.4 Adjustment of Short-circuit Welding Characteristics
-For unstable arc; Increase the value.
-For excessive spatters; Decrease the value.
• When arc occurs for a long time without sphere-drip
dropping; Decrease P49, increase P50 and P51.
• When arc is not stable;
Increase P49, decrease P50 and P51.
• To make beads flat for stainless-steel or the like;
Increase P49, P50, and P51
• When short-circuit occurs for a long time;
Decrease P parameter P49, increase P parameter P50
and P51.
• When burn-through occurs;
Decrease P parameter P49, P50, and P51.
• When weld penetration is needed;
Increase P parameter P49, P50, and P51.
