SAFETY CONSIDERATIONS ELECTRIC ARC WELDING EQUIPMENT Saftey CAUTION : READ BEFORE ATTEMPTING INSTALLATION, OPERATION OR Guidelines MAINTENANCE OF THIS EQUIPMENT 1-1 INTRODUCTION This equipment is intended for ultimate application by commercial/industrial users and for operation by persons trained and experienced in the use and maintenance of welding equipment. Operation should not be undertaken without adequate training in the use of such equipment.
the regulator from overpressure; it is not intended to protect any downstream equipment. Provide such protection with one or more relief devices. Never connect a regulator to a cylinder containing gas other than that for which the regulator was designed. Remove faulty regulator from service immediately for repair (first close cylinder valve). The following symptoms indicate a faulty regulator: Leaks - if gas leaks externally.
retinal burn that may leave a permanent dark area in the field of vision. or the equipment will become electrically HOT - a dangerous condition that can shock, possibly fatally. 3. Protection of Nearby Personnel Enclose the welding area. For production welding, a separate room or enclosed bay is best. In open areas, surround the operation with low-reflective, noncombustible screens or panels. Allow for free air circulation, particularly at floor level. Before welding, check ground for continuity.
Section A Installation Technical Specifications Wire Capacity • .023”, .030” & .035” (0.6, 0.8 & 0.9 mm) Aluminum Wire only Wire Speed* • 600 ipm (15.2 mpm) at 12VDC Motor Input Voltage Spool Size • 2-1/2” inches (63.5mm) Duty Cycle - All ratings are at 18V using Argon Gas • 20% @ 200 Amps • 60% @ 135 Amps *Maximum IPM varies depending on input voltage, wire size and the control box used. Support Equipment Required • • • CV or CC power source of sufficient capacity for your needs.
Section B Operation General Description The 12 VDC Sidewinder® motor is controlled by an external motor/wire speed controller. This can be an intergral circuit within a welding power supply or through an MK Control Module. The trigger is designed so when it is partially depressed, gas flow starts via the valve located in the gun body - prior to ignition of the arc. When the trigger is partially released after welding - just as the arc is extinguished, gas flow continues until the trigger is fully released.
NOTE: Changing the factory set idler roll pressure may cause the wire to feed erratically, negatively affecting wire feed speed and welding conditions and may damage moving parts within the welding gun. Drive Roll Removal/Installation 1. Push the idler roll release button. This will relieve the pressure against the drive roll. 2. Align the Drive Roll Removal Tool (P/N 931-0100) over the flats of the drive roll.

Section E Troubleshooting The Sidewinder® MiniSpool™ gun operates on a very simple principle. The torch trigger is designed so that when it is partially depressed, gas flow starts via the valve located in the torch body, prior to ignition of the arc. When the trigger is partially released after welding (extinguishing the arc), gas flow continues until the trigger is fully released; built-in pre and post gas flow.
Testing The Gun Motor Check Disconnect 4-pin CPC. Check the resistance across pins “3” and “4”. The resistance across the motor should be between 15-25 ohms. If an open circuit or short exists, check the motor leads and motor independently of each other. Replace the defective part. Testing the Micro Switch Check for continuity across pins “1” and “2” when the trigger is pulled. The signal should be open when the trigger is released.

SP-1 Connection Configuration OPERATION For a Sidewinder Direct-Connect to a welding power supply, which has front panel wire feed speed controls (variable DC motor voltage), the Sidewinder 4-pin control cable connect direct. (Fig. 1). Figure 1 If the welding power supply does not offer adjustable motor voltage, then SP-1 Speed Control Module must be used. The SP-1 uses standard 115VAC input power and connects to the trigger pins (closing contacts) of the power supply (Fig. 2).
SP-1 Connection Configuration Con’t. For many Miller (Fig. 3) and Lincoln (Fig. 4) welding power supplies, a 14-pin connector offers power to the SP-1 module and the trigger signal for contact closure. Figure 3 In addition to Miller and Lincoln units, many other manufacturers also utilize the same type of 14-pin connector, with the same pinouts and clocking. Consult the power supply owner’s manual and or manufacturer for pin location and labels.
