TIMER ADJUSTMENT
The MF-12 has been designed and built to withstand rugged shop and field usage. Constant, trouble-free operation is assured with a minimum of maintenance. The GUN TIP, the GROUND CLAMP and all CABLE CON-NECTIONS should be kept clean to maintain a good electrical contact. Wire brush the parts to remove any oxidation or adhesive that may have accumulated during the fastening operation.
"HEAT SINK"
The timer dial facing you on the front panel of the unit, determines the duration of the weld cycle. For maximum efficiency of the unit, the weld cycle should be set for the shortest length of time necessary to provide a good weld. An excessive amount of time does not improve the weld. On the contrary, the resulting weld may not be an acceptable one. It is recommended that at the start of a production run, using a given length of pin with a given gauge of metal, the opera-tor take a few moments to determine the minimum timer setting to perform the job and leave the timer at that point.NOTE: There is a common misconception that the longer the weld time, the stronger the weld. This is not true. It is important that you follow the above in-structions for maintaining the minimum weld time.
MAINTENANCE
Included with your MF-12 is a simple "heat sink" tool that looks somewhat like a cookie cutter. This tool, when placed behind the point of weld on bare metal, will eliminate any mark on the metal by dissipating the heat generated from the point of the weld. The use of a copper sheet on the work bench will also eliminate this mark.
ELECTRICAL REQUIREMENTS
Where duct is too large to put on a bench, snap the ground clamp onto the duct and secure the insula-tion quickly by welding the Clip Pins inside or outside of the ducts as required. Eliminate the heat mark on the duct using the simple "heat sink" supplied on the opposite side of the weld.
BRING MF-12 TO THE WORK
MF-12 AS A BENCH TOOL
Connect the MF-12 to a 208-240 volts - 60 cycle - 30 amp fused power supply. The MF-12 unit uses 220 volt single phase. To wire to 220 volt single phase, the green lead is ground and the white and black leads are power. To wire to 220 volt three phase, the green lead is ground and the white and black leads attach to any two of the other three legs. It is suggested that the unit not be wired into the power box permanently but rather plugged in so that the unit may be quickly unplugged and easily taken elsewhere in the shop or on the job.
To use your work bench as a welding table, set the MF-12 alongside or on top of the work bench. Cover the bench top with a copper sheet (.025 inch) which will act as a permanent ground when the duct work is placed on the table top. Attach the MF-12 ground clamp to the duct work or copper bench top. The Clip Pins will quickly weld every time with no burn marks or wasted pins due to misfires.
INSTALLING CLIP PINSClip Pins are welded as easily as "A", "B", "C".
"A"
Press down through the insu-lation, twist the gun, and pull the trigger. Do not release the trigger until the timer cycle has ended.
"B"
Position the Clip pin on the Magnetic tip of hand gun.
The Clip Pins are permanently welded in position flush with the insulation.
"C"
SERVICE The MF-12 has been designed and built to withstand rugged shop and field usage. The Indicator lights on the front panel will help you to diagnose minor prob-lems. If your MF-12 fails to operate follow this simple procedure to find the defective component.
1. Pull the trigger and watch the lights. The green light (24 volts) and then the red light (220 volts) should flash on and off.
2. If only the green light comes on, go to step 4.
3. If neither light comes on, press the WELD CYCLE TEST switch on the front panel. A. If both lights flash and the transformers do not hum go to step 5. B. If both lights flash and the transformers hum, the problem is either a bad trigger switch or bad switch cable. C. If only the green light flashes, go to step 4 D. If neither light flashes, replace 24 volt transformer.
4. Replace the weld activator.
5. The problem is probably a bad weld transformer. Call technical service for further assistance. (1-800-899-3876)
