Increase wire speed before
operating again

5. Wire feeds into ‘birds a) Wire welded to tip a) As above plus reduce feed roller
nest’ tangle pressure so that if blockage occurs
wire slips on roller i.e. no feed

d) Poor earth contact d) Check earth clamp/workpiece conn
9. Welder cuts out Duty cycle exceeded Allow welder to cool before
whilst in use (auto cut-out operates) continuing (Until amber light goes out)
Note: If duty cycle is continually
exceeded, damage to the welder
may result, and welder output is
probably too small for application
If you have any problems which cannot be resolved by reference to the above, or if you
require spare parts for your welder please contact your local Clarke dealer.
