Continuous Welding

Solution
Decrease speed.
Increase booster ratio.
Evaluate material.
Solution
Have horn analyzed for amplitude uniformity.
Check fixture design and dimensions.
Evaluate material.
Solution
Increase speed.
Reduce booster ratio.
Reduce air pressure.
Solution
Continuous duty applications require
cooling air (refrigerated air, in some applications).
Supply air to the stack interfaces and the horn tips.
