MMA welding when the stub of each electrode is thrown away. For every kilogram of coated
stick electrode purchased, about 65 per cent becomes part of the weld (the rest being
discarded). The use of solid wire and flux cored wire has increased this efficiency to 80-95 per
cent. MIG/MAG welding is a versatile process, which can deposit weld metal at a very high rate
and in all positions. The process is widely used on light to medium gauge steel fabrications and
on aluminium alloy structures particularly where high-rate manual operator production is
required. The introduction of flux cored wires is finding increased application in heavy steel
structures.

X: Rated duty cycle. It is the ratio between the load duration time and the full cycle time.
Note 1: This ratio is between 0~100%.
Note 2: For this standard, one full cycle time is 10min. For example, if the rate is 40%, the
loaded time shall be 4 minutes and rest time shall be 6 minutes.
Duty cycle is based on a ten minute period. This means that the arc may be drawn for two
minutes out of each ten minute period without any danger of overheating .If it is used more
than two minutes during several successive ten minutes peiods, it may overheat.
