Unpacking Your Tool; Before Use; Connecting To A Power Supply - Silverline Arc Welder Mode D'emploi

GB GB

Unpacking Your Tool

• Carefully unpack and inspect your tool. Fully familiarise yourself with all its
features and functions
• Ensure that all parts of the tool are present and in good condition. If any parts
are missing or damaged, have such parts replaced before attempting to use
this tool

Before use

• Always wear appropriate personal protective equipment for the job that you
are to do. Use of this machine requires a welding mask, gloves, heat resistant
clothing, and if appropriate a respirator
• Always ensure that you have an appropriate fire extinguisher near to the work
area
• Always inspect your machine for damage or wear. Pay particular attention to
leads and cables. If any damage is found DO NOT USE
• Check that all casings or covers are properly closed and secured
• Position the welder so as will not move, or tip, in use. Ensure that there is at least
500mm of clear space around the welder, to allow ventilation

Connecting to a Power Supply

• Important: This welder is not supplied with a mains electrical plug
• At full capacity it will draw far too much power for a normal mains plug and
socket
• This machine must be connected by a qualified person to a suitable power
supply capable of handling the current
• Please refer to the Specification for details of input capacity
• If in any doubt, do not attempt to connect or use this welder
Operating Instructions
Warning
• Always unplug the welding machine from the mains supply and allow to cool
completely before attempting to fit or replace any part
Setting Machine
• To achieve a good quality weld the Power Control Knob (5) must be set correctly
• Turn the control knob clockwise for increased current and anti-clockwise to
reduce the current
Welding Rod Selection
• In order to produce a good quality weld, the correct type of welding rod must be
used. Welding rods are available in a variety of thicknesses and materials, and
with a range of coatings
• See the specification table above, and refer to rod manufacturers guidelines to
select the correct rod for your requirements
Duty Cycle
• This machine is not designed to weld constantly. Excessive continuous welding
would cause overheating and damage to internal components
• The duty cycle (see specifications) defines the number of minutes, in every ten
minutes, that the machine can weld
• For a duty cycle of 30%, the machine may be used for 3 minutes, then must be
allowed 7 minutes to cool
• Using the machine at reduced current settings, and maintaining good ventilation
will maximise the duty cycle
Thermal Cut-Out
• This machine is equipped with a thermal cut-out. If the machine is overloaded,
or used beyond its duty cycle, it will automatically shut down
• Allow the machine to cool. The cut-out will automatically reset once the
machine is ready to be used
Preparing to Weld
• Ensure that parts to be joined are clean, and free from rust, paint, or other
finishes
• All parts should be well supported, and there should be a gap of approximately
1mm on the intended joint
• Attach the Earth Clamp (7) to a clean, bare earthed area of one of the parts, as
near as practical to where the joint will be
• Check the Power of the welder is set correctly
• Squeeze the Electrode Clamp (10) to open the jaws. Place an electrode into
the jaws, and release. The electrode should be firmly gripped, with the clamp
contacting the clean metal part (not the coated part)
Welding
• WARNING: Using a welder correctly is a technical skill. A welder used
incorrectly can be highly dangerous. The information presented below is general
guidance only. If you are not entirely confident in your ability to use this tool
safely DO NOT USE
6 6
• Move the On/Off Switch (1) to the 'ON' position
• Hold the Electrode Clamp (10) in one hand, and the face mask in the other
• Position the rod at an angle of approx 80˚ to the surface, with the tip
approximately 30mm away from the metal
• Hold the Welding Mask (13) over your face, and tap the rod against the metal
• An arc should strike between the metal and the tip. Try to hold the tip of the rod
a distance away from the metal equal to the rod thickness. Maintain the arc for
1-2 seconds, then move the rod away
• Allow the weld to cool slightly, and move the mask away from your face. If the
settings were correct, a round 'spot' weld should have formed
• If the weld has not fully penetrated the metal, increase the power using the Power
Control Knob. (5) If a hole has been made in the metal, reduce the current setting
• Practice making 'spot' welds until you are confident in the use of the machine,
including selecting settings
• To form a 'seam' weld, maintain the arc for longer, and slowly move the rod
forward at the same time. The speed at which the rod is moved is crucial to
achieving a good weld
• If the machine settings are correct, the arc should be steady, and produce a
crackling sound. It will be necessary to gradually move the electrode clamp
closer to the metal as the rod is used
• When welding is complete, remove excess and splatters using the Chipping
Hammer & Wire Brush (12)
• Creating neat, high quality, welds is a skill that takes time to master. Practice
and good preparation will help to create satisfactory welds
• Warning: Disconnect the inverter from the power supply and wait for the circuit
light to go out before attempting to open the unit
• Remove the cover from the inverter on a regular basis and remove dust
by passing a low pressure air flow through the inside. The cover should be
correctly and securely replaced before attempting to use the inverter. Keep the
outside cover of the inverter clean at all times by wiping with a soft dry cloth
Troubleshooting
Should you experience any problem with the inverter please check:
• That the welding current is correct for the diameter and type of electrode in use
• That if the power supply is on, the power indicator light in the On/Off switch is
on. If the power indicator light is not on there is a power supply problem (for
example a circuit breaker may have blown)
• That the correct voltage is being used as indicated on the rating plate
• That the Overload Protection Light (4) is not illuminated
• That the normal intermittence ratio is correct and that the fan is working
efficiently
• That the cables are undamaged and that there is nothing causing a short circuit
• That all circuit connections are correct. You should pay particular attention to the
work clamp, ensuring that it is correctly attached to the workpiece and there is
no grease, paint or other contaminate that could cause a bad connection
Disposal
• Do not dispose of power tools, or other waste electrical and electronic
equipment, with household waste
• Contact your local waste disposal authority for information on the proper way
to dispose of tools
