Component Check points Advisories
Grounding cable − Check if all earth wires (for this
device and parent metal
grounding) are in place – check
if the connections are safe and
reliable.
In order to avoid the risk of
electrocution, be sure to conduct
related checks.
Cable − Check if the cable insulation
layer is worn, has other damage
or conductive components are
exposed.
− Check if the cable suffers
abnormal exterior force.
− Check if the connection of the
cable connecting with the
parent metal is reliable and firm.
Adopt a checking routine
encompassing the conditions of the
welding site. Daily checks should
be fairly simple, whilst regular
checking intervals should be more
in-depth.
Important! In order to prevent the semiconductor and P plate from being damaged by static, please follow the
instructions below:
− Before touching the conductor of the cables and P plate inside the unit, you must remove the static in advance by
touching the housing metal position with your hand, etc,.
− In order to maintain the performance of this product over time, regular checking is advised.
− Inspect and clean the housing interior. Remove any dirt, dust or foreign matters. Use compressed air without
water (dry air) to blow accumulated detritus away.
− Regular checking intervals should generally be conducted every 6 months. However, this should be extended to
every 3 months if workplace conditions are regularly dusty or contains oily smoke and fumes.
9.2 TROUBLESHOOTING GUIDE
Faults Possible causes Solutions
The fault indicator off, no HF
discharge rustling, and arc
striking effective
− The arc striking transformer
primary cable has a poor touch
with the power plate.
− Re-tighten
− The discharging nozzle is
oxidized or is too far.
− Remove the oxidized
membrane on the surface of the
discharging nozzle, or adjust its
distance to approx. 1mm.
− The manual welding Argon
welding switch is broken.
− Replace
− Some components of the HF
arc striking circuit is damaged.
− Find and replace.
Large ARC splashes and very
hard burning of the alkali
welding rod
− Wrong polarity
− Exchange the polarity of the
earth wire and the handle wire.
