Choose for appropriate duty cycle - Duty cycle indicates how many minutes out of 10, a MIG welding machine will continuously operate at full power.Choose a machine with an appropriate lowest Amp setting for thin materials, and for thick materials make sure the machine has at least 30% higher power output than estimated, to avoid overheating issues. A rule of thumb is roughly 30 Amps are required for every mm of material thickness. Estimate your required current (Amp) range - Lowest and highest available MIG Amp settings are equally important for welding thin and thick materials respectively.Know your application - Important factors to know before getting started, are the types of materials you need to weld, material gauge (thickness), welding speed & productivity requirements, cost constraints, portability needs, environment conditions and specialized application requirements.Things to consider when buying a MIG welding machine: Among the huge line of welding machines & accessories found on IndustrySearch are some of the best MIG welders on the Australian market. Find and buy the MIG welder that’s right for you from verified suppliers on IndustrySearch.
