Frequently Asked Questions - H-3000 Vevor

How to adjust the electrode pressure?

Use the supplied 6 mm hex key to turn the adjustment device under the handle. Turn clockwise to increase pressure, counterclockwise to decrease it. Refer to the graduated indicator on the handle to know the applied force.

What is the maximum sheet thickness I can weld?

The maximum recommended thickness is 2+2 mm (two sheets of 2 mm each). For higher thicknesses, the machine may not work correctly.

What to do if the control panel lights flash?

This indicates transformer overheating (thermal protection activated at 95 °C). Let the welder cool down for at least 5 to 20 minutes before using again.

How to choose the welding mode: normal or pulsed?

Use the mode button on the panel. Normal mode (lower LED) is suitable for most work. Pulsed mode (upper LED) improves welding capability on high-resistance sheets or with special coatings.

What are the essential safety precautions?

Always wear safety goggles, gloves and protective clothing. Ensure good ventilation, keep flammable materials away, and unplug the device before any maintenance.

Can I use the welder outdoors?

No, the welder is designed for indoor use only. Do not use in a humid or wet environment.

How to adjust the welding time?

Turn the knob (1) on the control panel to increase or decrease the welding time relative to the default factory setting.

What extension cable cross-section is recommended?

The minimum extension cable cross-section must be 2.5 mm². If using a reel, unwind it completely before plugging in.

How to align the electrodes?

Loosen the arm locking screws, slide the arms in the clamps to align the electrodes in both planes, then retighten. Use sheet samples to verify alignment.

What to do if weld quality is poor?

Check that the micro-switch is activated at the end of the handle stroke, that the clamps and screws are tight and not oxidized, and that the parameters (time, pressure, diameter) are correct. If the problem persists, contact an authorized service.

- WARNING! Ensure that you read and understand the safety instructions in Section 1.

4.1. Connection to mains power supply.

Before making any electrical connections check that the voltage of the available power supply is suitable for the spot welder model that you purchased. (See specification above.)

4.2 The spot welder model requires a 30amp supply and is suitable for either single phase or three phase connection. 4.3 The spot welder model requires a 32 amp plug. If connecting to a 30amp supply, wire the plug as shown on

5. SETTING UP TO WELD

- WARNING! Ensure that you read and understand the safety instructions in Section 1.

Before carrying out any spot welding operations, the following series of checks and controls must be carried out with the welder disconnected from the power supply.

5.1 Setting up and adjusting the arms. (Refer to fig. 2) Obtain samples of the metal to be welded and place a double thickness of the sheet onto the lower electrode. Depress the welding lever until the upper electrode makes contact with the upper face of the sheet metal. At this point the axis of the electrodes is aligned in both planes. Make any necessary adjustments by loosening the arm

locking screws at (A) and sliding the arms in or out of their clamps until the electrodes are aligned when viewed from the side. Before tightening the clamp again, view the electrodes from the front and if necessary rotate the arms in the clamps until the electrodes are aligned. (See A1). When satisfied with the alignment, retighten the screws.

5.2 Setting up and adjusting the electrodes. (Refer to fig. 2) To adjust the electrodes correctly, the handle should be locked in a special position approximately halfway through its travel. To do this, insert the M6 socket cap bolt provided into the threaded hole indicated (1). Turn the bolt clockwise with fingers until it stops against the handle, and then unscrew it 1/4 turn. Depress the handle through approximately half its travel and turn the screw clockwise again by another 2 or 3 turns so that it engages the locking notch. You may have to adjust the position of the handle slightly up or down to get the lock aligned with the notch. Loosen the clamp bolt at (B) on the lower arm and adjust the electrode up or down to the desired position and tighten securely again. Loosen the clamp bolt at (B) on the upper arm and allow the electrode to slide downwards to rest on the lower electrode. Slide two sample

thicknesses of the sheet metal to be welded between the electrode tips, allow the upper electrode to rise, and retighten the upper electrode clamp bolt. Then

tighten the locking bolt.

5.4 Adjusting the pressure exerted by the electrodes. (Refer to figs. 3 & 4) The pressure exerted by the electrodes onto the workpiece can be adjusted by altering the spring pressure adjuster underneath and within the handle using the 6mm Hex key provided (fig. 3-1). To increase the pressure, turn the adjuster clockwise. To decrease the pressure, turn the adjuster anticlockwise. On the face of the handle there is a graduated indicator which shows the pressure using the standard 120mm arms. Refer to fig. 4 to see the values allocated to graduations. Refer to the chart below to see how the pressure decreases when longer welding arms are used. Once the electrodes make contact with the sheet metal, the downward movement of the handle firstly clamps the workpiece and then makes contact with a micro switch to turn on the current. If the pressure you have set begins to limit the action of the handle, you must decrease the pressure to allow the handle to travel down to activate the micro switch.

ARM LENGTH	FORCE / PRESSURE EXERTED ON WORKPIECE (NEWTONS / KILOGRAMS)
120	1200 / 122.3	1000 / 101.9	800 / 81.5	600 / 61.2	400 / 40.8
250	770 / 78.5	550 / 56.0	430 / 43.8	320 / 32.6	230 / 23.4
350	470 / 47.9	380 / 38.7	330 / 33.6	230 / 23.4
500	280 / 28.5	250 / 25.5	180 / 18.3

An eyebolt and spacer can be ordered to enable the unit to be suspended on a production line, etc. The eyebolt must not be fitted without the spacer. See fig. 3-2.

6. OPERATING INSTRUCTIONS

6.1 Use the control panel on the side unit to set the main parameters for welding (See fig. 5, right).

1) WELDING TIME: Use button (1) to increase or decrease the welding time in relation to the factory default setting. 2) WELDING THICKNESS: Use button (2) to select the thickness of sheet metal to be welded.

3) WELDING MODE: Use button (3) to select the welding mode.

Normal Spot Welding: The lower LED adjacent to the straight line symbol selects the normal continuous spot welding mode. Pulse Spot Welding: The upper LED selects a pulsating welding current which improves welding capacity on sheets with high yield points or on sheets with special protective films. The pulsation period is set automatically and does not require adjustment.

6.2 Thermostatic protection LED indicator.

When all the LEDs on the control panel go off and the two welding mode LEDs (See fig. 5-4) begin to flash alternately, this indicates that the transformer is beginning to overheat and the thermal cut out has operated.

Allow the welder to cool for at least 5 minutes before attempting to weld again.

6.3 SPOT WELDING PROCEDURE.

- WARNING! Ensure that you read and understand the safety instructions in Section 1.

Use welder in a suitable working area. Keep area clean and tidy, free from unrelated materials and ensure there is adequate lighting. DO NOT allow untrained persons to operate the welder.

6.3.1 Ensure that you are fully prepared with all workpieces securely held and presented ready for spot welding.

6.3.2 Ensure that the welding arms and electrodes are correctly set up for the thickness you intend to weld. (See Sections 5.1 & 5.2)

6.3.3 Ensure that you have correctly set the clamping pressure for the thickness you intend to weld. (See Section 5.3)

6.3.4 Turn on the mains power supply.

6.3.5 On the model, set the welding time, welding thickness, and welding mode required using the control panel on the side of the unit. (See Section 6.1)

6.3.6 Manoeuvre the unit so that the workpiece is between the arms. Allow the electrode to bear on the underside of the sheets to be welded.

Depress the welding lever until the upper electrode makes contact with the workpiece. Pause and check that the electrodes are positioned where the weld is required. If satisfied, continue to depress the lever to clamp the sheets together until the lever reaches the end of its travel and operates the micro switch which turns on the welding current.

6.3.7 Do not release the clamp lever immediately but pause for a few moments first. This will give the weld improved mechanical characteristics. 6.3.8 When all welds are completed, turn off the mains power supply. Disconnect the unit and clean it. Store in a dry and safe environment until next required.

(The effectiveness of spot welds should occasionally be tested to ensure you are using the right settings. When two spot welded sheets are separated, the area of the spot weld itself should not tear apart but remain attached to one of the sheets, indicating that the weld is stronger than the surrounding sheet.)

7. MAINTENANCE

- WARNING: Unplug from the mains power supply before performing maintenance or service.

7.1 Ensure the welder and cable are in sound condition and good working order. 7.2 We recommend that you have your welder serviced on a regular basis by an authorised service agent.

During any inspection of the inside of the machine for repairs or cleaning, the following checks should be made.

7.2.1 Remove dust and metallic particles deposited on the transformer and/or internal walls etc., using a jet of dry compressed air (max 10 bar). Do not direct the jet of compressed air onto the electronic circuit boards; clean them with a very soft brush if necessary. 7.2.2 Check the wiring for insulation damage or loosened/oxidised connections. 7.2.3 Check that the screws connecting the flexible element to the transformer and to the upper arm supports are tightened up and there are no signs of oxidation or overheating. 7.2.4 Replace or repair damaged parts. Use recommended parts only; unauthorised parts may be dangerous and will invalidate the warranty. 7.3 Keep the welder clean for best and safest performance. Do not clean with water, strong solvents, paint thinners or gasoline. 7.4 If welding performance is poor, make the following preliminary checks.

7.4.1 When the welding/clamp lever is depressed, make sure that the spigot at the end of the handle on the underside actually touches and presses the micro switch, thus turning on the welding current.

7.4.2 Check the security and condition of the arm holder clamps and screws, and the electrode clamps and screws. If these are loose or oxidised, it will affect the efficiency of the welder.

7.4.3 Check that the welding parameters are correct in terms of welding time, electrode pressure, and diameter.

7.4.4 If these checks do not reveal the source of the problem, take the weld to an authorized service agent.

8. OPERATION INSTRUCTIONS

Press down the handle to make the welding electrodes clamp the sheet metal.

Use the tip on the handle to activate the trigger.

Press down the handle hard to activate the welding trigger.

Note:

1. The thermal will activate to stop working when the transformer temperature reaches 95°C. It can be used again 15-20 minutes later. 2. Please do use the sheet metal thickness less than 2mm when trying the metal. When the metal thickness is more than 2mm, it cannot work.
