LINCOLN electric-welding units suitable for use in vehicle workshops are the Type SA.150 and 200 motor generators and the Arcmaker AC375 welding transformer. As well as these units, a wide range of arcwelding electrodes are manufactured by the company.
A large number of welding applications come within the range of the SA.150 and SA.200 units; they will weld most metals and alloys and do hard-facing work. The units are of the motor-generator d.c.-arc type and in the SA.150 there is a 7-5-h.p. motor and in the SA.200 a 10-h.p. motor. Connection is for 440 volts but the welders can be supplied for 220 or 550-volts, 3or 2-phase. The current range when welding at a 30-V arc is 30 to 200 amp. for the SA.150 and 30 to 250 amp. for the SA.200.
The type of arc needed for any class of job can be selected; for example, high settings on the voltage control give a highspeed type of arc which is ideal for normal down-hand welding, whilst low settings give a forceful, digging type of arc which is recommended for overhead and vertical welding in order to produce quality welds with minimum spatter,
The Arcmaker AC.375 is an oil-cooled a.c. welding transformer for single-operator, manual arc welding and will deposit all types of electrodes—including mild steel, stainless and specials—efficiently and economically. The unit is of the oil-immersed, naturally cooled type and provides an 80-V opencircuit tapping for use with all types of mild-steel electrode and a further tapping for 100-V open circuit to give the best results with low-hydrogen and iron-powder type electrodes and the difficult electrode coatings used for the welding of stainless steel and so on. A welding current range of 25 to 375 amp. at 80 V and 35 to 320 amp. at 100 V is sufficient to take full advantage of economies possible with modern electrodes and is more than adequate for average requirements. On each open-circuit-voltage tapping 52 current settings are obtainable, these being carefully arranged to ensure ideal settings for each type of electrode.
Welding electrodes made by the company cover every conceivable need of a vehicle workshop.
