1. INTRODUCTION Danger of ultraviolet radiation. 1.1 SCOPE This MIG/ARC welding machine is designed to weld ferrous metals such as steel and iron. This machine can perform MIG and ARC/MMA welding. This product is suitable for enthusiasts and tradespersons alike. Any application other than that it was intended for, is considered misuse.
Electric shock can kill: Do not incinerate or throw onto fire. – Remove the plug from the socket before carrying out adjustment, servicing, or maintenance. For indoor use only. Do not expose to rain. – Allow 5 minutes waiting time for the capacitors to discharge before removing the panels for any maintenance operations – Do not touch live electrical parts. Class 1 appliance (Must be earthed). – Never use electrode holders or cables with damaged or deteriorated insulation.
– Before starting a weld ensure the area is clear of flammable materials. – Remove any inflammables to a safe distance, especially substances likely to generate a dangerous vapour. – The welding arc can cause serious burns. Avoid contact with skin. – In the welding environment, damaging levels of noise can exist. Wear hearing protection if the process dictates. – Do not touch hot equipment or metal. Allow the weld time to cool, use the correct tool and wear protective welding gauntlets.
– All equipment should be kept in good working condition, inspected and, when defective, promptly repaired or withdrawn from service - All equipment should be placed so that it does not present a hazard in passageways, on ladders, or stairways, and should be operated in accordance with the manufacturer’s instructions. – In the vicinity of an arc, non-reflective curtains or screens shall be used to isolate persons from the arc radiation. A warning, e.g.

6. insert the plug into positive coupling (11) and twist clockwise to lock. ASSEMBLING THE WELDER Attach the earth clamp (15) to the negative coupling (13) and twist clockwise to lock. Make sure the power supply information on the machine’s rating plate is compatible with the power supply you intend to connect it to. 7.4 INSTALLING THE FILLER WIRE (MIG WELDER) – FIGS. 1 - 5 A suitable plug must be fitted by a qualified electrician.
and tensioner (21.1). Note: Ensure the tip size matches the wire size prior to installing. (21.1) (21.2) (14.1) (14.2) (21.3) FIG. 2 FIG. 5 7. Connect the welding machine to the power supply. 8. Attach the Polarity change plug (12) as illustrated for either GAS or GASLESS. GASLESS MIG WELDING 10. If bottled gas is required for weld it will be fitted via the hose barb (18) on the back. 7.
clean of grease, dirt, paint and rust. Clean with a wire brush as necessary. Position the earth clamp as close as possible to the working area and ensure a tight grip is achieved. Select the welding current based on the thickness of the material. A thick piece will require a high current, however due to the duty cycle this will effect the welding time by significantly reducing it. A thin piece will only require minimal heat and so the current can be less. This will allow a longer period of welding.
Lower the electrode down toward the parent metal and strike the arc. 8.4 ARC WELDING, FILLER ROD (ELECTRODE) SELECTION – FIG. 10 The correct selection of electrode size and type will vary for each application dependent upon material thickness, material type, amperage and equipment, however as a guide the figures below provide an indication. MMA Electrode Material Thickness ≤1.6mm 1-1.5mm 2.0mm 1.2-3mm 45 - 75A 2.5mm 2-5mm 75 - 110A 3.25mm 4-8mm 100 - 150A (16.
and/or seek training on the subject. Use of an anti-spatter spray Draper stock No.05709 will help to achieve a cleaner finished weld. This welding power source has a maximum material thickness capability of 5mm. electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air. 8.7 THERMAL CUT-OUT If welding for extended periods the thermal cut-out will activate prohibiting use of the machine until sufficiently cool.
9. TROUBLESHOOTING 9.1 TROUBLESHOOTING WARNING: For your own safety, turn the switch off and remove the plug from the power supply socket. PROBLEM POSSIBLE CAUSE REQUIRED ACTION Dirty current nozzle (contact tip). Clean. May be an obstruction at the contact tip. Remove obstruction. Too low clamping pressure of the wire feed pulley. Increase the clamping pressure. Damaged current nozzle. Replace. Burnt current nozzle. Replace. Dirty driving gear torch liner. Clean. Cut on worn driving gear.
11. WARRANTY 12. DISPOSAL 11.1 WARRANTY 12.1 DISPOSAL Draper tools have been carefully tested and inspected before shipment and are guaranteed to be free from defective materials and workmanship. – At the end of the machine’s working life, or when it can no longer be repaired, ensure that it is disposed of according to national regulations.
