Pressure
adjusting handle
Check the tensioner adjustment dial is
fixed and adjusted to the desired
position.
The unfixed pressure-adjusting leads to the unstable
welding output and can crush wire.
Check if there is dust or spatter inside
the hose or beside wire-feeding wheel.
Check if there is a diameter agreement
of wire and wire-feeding hose.
Non-agreement of the diameter of wire and wire-feeding
hose possibly leads to the excessive spatter and unstable
arc.
Check if rod and wire feeding groove
are concentric.
Unstable arc possibly occurs.
Wire-feeding
drive roller
Check if there is an agreement of wire
diameter and wire-feeding wheel.
Non-agreement of wire diameter and wire-feeding wheel
possibly leads to the excessive spatter and unstable arc.
Check if the wire groove is blocked.
Check if the pressure adjusting wheel
can rotate smoothly, and it is physically
complete.
Unstable rotation or physically incompleteness of the wheel
possibly leads to unstable wire feeding and arc.
Check if the cable of torch is
twisted.
The twisted torch cable leads to unstable wire feeding and arc.
Check if the coupling plug is in loose
connection.
Check if the cable is physically
complete.
Relevant measures should be taken to obtain stable weld and
prevent the possible electric shock.
Check if insulation damaged or
loose connection exists.
Check if the cable is physically
complete.
Check if insulation damage or loose
connection exists.
Check if the earth cables are well
fixed and not short-circuited.
Relevant measures should be taken to prevent the possible
electric shock.
Check if this welding equipment is
well grounded.
Warning!
Protect the machine from rapid power switching. When the machines senses that the power is turned on and off
rapidly the unit will turn off. The power indicator light will not turn on. Allow the machine to rest for a few
minutes and normal operation should continue.
If this does not rectify the issue, please contact your approved WELDCO Technician.
