9. WELDING PROCEDURE
p
WARNING! Ensure you have read, understood and follow the safety instructions. Place the welding mask in front of your face before striking the arc.
9.1.
ARC WELDING
p
9.1.1.
Strike the electrode tip on the workpiece as if you were striking a match.
p
WARNING! DO NOT hit the electrode on the workpiece, as this may damage the electrode.
9.1.2.
As soon as the arc is struck, maintain a distance from the workpiece equal to the diameter of the electrode being used. Keep this distance as constant
p
as possible for the duration of the weld. As you advance along the workpiece the angle of the electrode must be sustained between 20
9.1.3.
At the end of the weld bead, bring the end of the electrode backward in order to fill the weld crater, quickly lift the electrode from the weld pool to
extinguish the arc.
9.2.
TIG WELDING (TIG Welding accessory kits available, contact you Sealey dealer).
TIG (Tungsten inert gas) shielded welding uses an arc between a tungsten electrode and the work to fuse the joint. The electrode itself is not molten
but filler metal is required to build the weld profile.The process is protected from atmospheric contamination by a shield of inert gas. This gas is
normally pure argon, but helium by itself or a mixture of helium and argon may be used for special applications. For stainless steel use a mixture of
argon and hydrogen.
9.2.1.
Strike the electrode tip on the workpiece as if you were striking a match.
p
WARNING! DO NOT hit the electrode on the workpiece, as this may damage the electrode.
9.2.2.
Point the electrode in the direction of the weld at about 2.5mm distance from the surface, and use the arc to melt the metal at the joint.
p
9.2.3.
Use the knob on the regulator to increase or decrease the flow of gas, .
9.2.4.
Filler metal may be added by using cut lengths of wire over 1.5mm diameter (usually 1 metre in length). To use filler metal (for example when making a
fillet weld), add such to the leading edge of the weld pool.
10. MAINTENANCE
p WARNING! DISCONNECT FROM THE MAINS ELECTRICAL SUPPLY AND WAIT FOR CIRCUIT LIGHT TO GO OUT BEFORE ATTEMPTING TO OPEN THE UNIT.
Periodically remove cover and lightly remove dust inside the machine by passing a low pressure air flow through. Ensure the cover is correctly replaced and secured
before attempting to use the welder.
Keep the outside of the machine clean by wiping with a soft dry cloth.
For any other service or maintenance, contact your local Sealey service agent.
11. TROUBLESHOOTING
Should you have a problem with the welder check to ensure the following are correct:
l Check the welding current, which is regulated by the potentiometer with a graduated amp scale , is correct for the diameter and type of electrode being used.
l When the mains rocker switch is on, check that the green mains lamp is ON. If this is not the case then there may be a mains supply problem.
l Check the yellow LED i.e. has the thermal protection interruption activated? This indicates either an over or under voltage or short circuit. If the thermal
interrupter has activated, wait for the machine to cool down before restarting.
l Check the normal intermittence ratio is correct, and check that the fan is working correctly.
l Ensure you are using the correct voltage.
l Check the machine output and ensure there is nothing causing a short-circuit.
l Check all circuit connections are correct. In particular check work clamp is correctly attached to the workpiece. Ensure there is no grease, paint etc on the surface.
