When MIG/MAG welding, not only the set welding current or wire speed affects the quality of the weld seam, but also the behaviour of the wire at the start of the welding process.
The so-called creep speed is a supporting function that comes into play at exactly this moment and ensures a controlled, smooth welding start.
What does creep speed mean?
Creep speed refers to a reduced wire feed speed at the start of the welding process.
The welding wire is initially fed towards the workpiece more slowly. Only after the arc has been safely ignited does the machine automatically increase the wire feed to the set working value.
Simply put:
At the start, the wire is rather than hitting at full speed straight away.
Why is creep speed used?
Starting with full wire feed speed can result in harsh short circuits, spatter, or an unstable arc.
Creep speed reduces these effects by giving the wire more time to make controlled contact and ignite the arc stably.
Advantages of creep speed
Smoother, more controlled arc start
Less spatter at ignition
Lower stress on wire, contact tip and torch
Better starting behaviour on thin sheets
Consistent results during frequent spot welding / start-stop welding
When is creep speed particularly helpful?
The function is particularly noticeable:
when tacking
on short weld seams
on thin materials
when changing welding positions
It ensures a much more relaxed welding experience, especially for beginners.
Summary
Creep speed is a supporting function in MIG/MAG welding that reduces the wire feed at the start to produce a clean and stable arc.
It improves seam quality, reduces spatter and protects torch components – without any extra effort for the user.
