WELDING TORCH
Component
To check Remarks
Air vent
Check if the torch is properly connected and if there are
any deformations.
Check if it produces splatter. The welding torch might burn out
(use spatter resistant materials)
Electric outlet
Check if the torch is properly connected.
The screw thread of the welding
torch may be damaged.
Check if the head is damaged and if the orifice of the outlet
is blocked. May cause unstable arc or block
arc starting.
There may be an air leak
Daily checking
Check the size of the tube extension piece.
The tube must be at least .230’’. If
the extension piece is too small, the
arc is unstable.
Check if the diameter of the wire matches the inner
diameter of the tube. May cause unstable arc. Use an
adequate tube.
Check the reel and the extension piece.
May result in poor wire supply and
unstable arc. Change the tube.
May result in poor wire supply and
unstable arc (clean the tube with
kerosene or change it)
Check for blockage caused by dirt or wire residue.
Wire supply tube
1. The tube was damaged by the
heat. Change it.
2. Change the O-ring.
Check if the wire supply tube is damaged or the O-ring is
worn down.
CABLES
Component
To check Remarks
Cable of the welding
torch
1. May cause poor wire supply.
2. If the cable is bended too
much,
the arc will be unstable
Output cable
The insulation is worn down.
The cable connector is naked (damaged insulation) or
loose (primary point between the power supply and the
cable) For your safety and to ensure a
s t a b l e w e l d i n g , s e l e c t t h e
appropriate method to carry out

Check if the power supply connector and the protective
equipment are connected properly.
Check if the safety equipment is connected properly.
Check if the connector of the input cable is connected
properly.
Ensure that the input cable is not worn down and that
the conductor is not exposed.
Input cable
Grounding cable
Check if the ground cable connecting to the power
supply is not broken and ensure that it’s connected
properly.
Check if the ground cable connecting to the workpiece is
not broken and ensure that it’s connected properly.
Carry out daily inspection to extend
the lifetime of the machine and to
guarantee security.
Check if the cable of the welding torch is bent too much.
Check if the mobile connector is well connected.
