THE WELDING SHIELD
- Push the two halves of the shield together as shown, making sure the hooks and pins on the side engage correctly.
- Place the handle into position and secure using the plastic nut provided.
- Working from the inside of the shield, insert the clear glass panel into the recess in the shield, followed by the dark glass panel.
- The clear glass must be inserted first.
- Insert the two plastic screws to clamp the glass panels from the inside of the mask.
When replacing the glass panels,
only use parts supplied by Clarke International. The dark panel is a
certified, specific optical class, and should not be exchanged for any other
type.
The clear glass panel should be replaced when it becomes badly pitted.
PREPARATION FOR USE
FITTING THE WELDING ROD
- Select the appropriate welding rod, and insert it into the welding rod holder.
- It should be approximately the same thickness as the workpieces being welded.
PREPARING THE WORKPIECE
The area being welded should be perfectly clean. Any coating, plating or corrosion must be removed, otherwise a good weld will be impossible to achieve.
- It should be approximately the same thickness as the workpieces being welded.
OPERATING THE WELDER
THERMAL CUTOUT
If the machine stops at any time and the amber light on the front panel
illuminates, the thermal cutout has activated.
Wait until the transformer has cooled sufficiently (the amber light goes out)
before restarting work.
ATTACHING THE EARTH CLAMP
Attach the earth clamp firmly to the workpiece as close as possible to the
point of weld.
IMPORTANT: Ensure that the earth clamp is attached to clean, solid metal.
necessary, thoroughly clean with a wire brush or similar to guarantee a good
connection.
SWITCHING ON
- 1. Select the welding current by turning the handwheel and observing the setting on the scale, on top of the machine. The chart below is an indicator of the thickness of material/ welding rod thickness and the corresponding welding current. This is intended as a guide only.
Size of welding rod| Amperage setting
---|---
16 swg| 1.5 mm| 40-55 Amps
14 swg| 2.0 mm| 50-70 Amps
12 swg| 2.5 mm| 75-95 Amps
NOTE: With practice you will get a feel for the best current settings for different welding rod thicknesses.
- Switch ON the machine.
STRIKING AN ARC
IMPORTANT: BEFORE you strike an arc, always bring the face shield up to protect your eyes.
-
Line up the electrode exactly over the spot where you want to strike.
-
Position your shield in front of your face and tap the electrode down firmly. Once you tap down and contact is made, you must instantly raise the electrode to the required arc gap.
- The arc gap should be roughly the same as the diameter of the electrode.
- If you withdraw the electrode too far once the arc is struck, you will lose the arc and have to try again.
NOTE: One thing that usually happens when you are striking an arc is that the electrode sticks to the work. It should come unstuck with a sharp tug. If it will not free easily, turn off the welder immediately as it will quickly overheat, then give the join a tap from the chipping hammer. As you get more experienced, this will happen less.
-
Once the arc is struck, move the electrode along its intended path, keeping the tip in the molten pool at all times.
- You must also get used to feeding down the electrode steadily as it burns away.
- An even crackling noise should be heard, which is an indication of a good weld.
-
Inspect the job carefully, the area of weld should be complete fusion of the electrode and parent metal(s).
- Any slag which forms on the surface should be chipped away with the hammer/brush supplied.
- If the resultant weld looks messy and irregular, this is an indication of porosity or slag contamination, and you have almost certainly failed to achieve the correct combination of speed and current. This is a common problem, so do not worry as practice will quickly cure this.
- When using the welder outside, you may need to take measures to erect a windbreak to make sure the shielding gas is not blown away, thereby leaving a poor-quality weld.
WELDING PITFALLS
The arc welding technique is an acquired skill and requires considerable practice before perfect results are obtained. The diagrams below will help to explain the pitfalls in your technique and how to overcome them.
-
ARC TOO SHORT
This causes irregular masses of weld to be deposited, with slag contamination on an uneven surface. -
ARC TOO LONG
This causes poor penetration resulting in a weak weld with excessive spatter and porosity. The surface of the weld is rough and the arc makes a hissing sound -
THE ELECTRODE MOVED TOO SLOWLY
This causes a very wide and heavy deposit that overlaps at the sides. It is wasteful both in terms of time and electrode use. -
THE ELECTRODE MOVED TOO QUICKLY
This causes poor penetration with a ‘stringy’ and incomplete weld deposit. Slag is very hard to remove. -
CURRENT TOO LOW
This causes poor penetration and causes the electrode to stick to the workpiece too readily. Also results in a very irregular and high weld deposit. Slag is very hard to remove. -
CURRENT TOO HIGH
This causes excessive penetration with spatter and deep pointed crater. It may also cause holes to be burned in the workpiece.
Burns electrodes very quickly. -
THE PERFECT WELD
With the correct combination of arc length, current regulation, inclination and speed of the electrode, you will, with practice, produce the perfect weld.
This should be regular with uniform ripples and no slag contamination. The arc will make a steady crackling sound.
MAINTENANCE
WARNING: ELECTRICITY CAN KILL – NEVER TOUCH LIVE ELECTRICAL COMPONENTS.
WARNING: DISCONNECT THE POWER SUPPLY BEFORE ALL INSPECTIONS AND MAINTENANCE
OPERATIONS
WARNING: BEWARE HOT SURFACES.
WARNING: ALWAYS LET THE POWER SUPPLY COOL DOWN BEFORE ACCESSING INTERNAL
COMPONENTS.
Frequency of maintenance operations depends on the operating conditions, how
intensively the welder is used and how clean or dirty the welding site is
(aggressive atmospheres etc).
Always inspect the earth return and torch hose before use, to ensure they are
in perfect condition and that the earth clamp is clean and secured correctly
to the cable.
As a general rule, the power supply should be inspected at least annually.
Consult your CLARKE dealer for advice if necessary.
