Welders.
 
 
Welders:
Most boat kit builders build their boats at home, and only have 240V mains power. Because of this, the selection of welders is limited to 240 Volt machines. As some builders may have 3 phase power we have listed both types of machines.

There are three types of 240 volt machines used for welding aluminium and steel. These are (1), The standard Transformer machine, (2) The newer style of Inverter machine and (3) The top of the range Pulse Mig machine. All of these machines are available for operation on 240 Volts.

At our aluminium welding and boatbuilding courses, we allow students to operate all types of welders. We have 7 of these Pulse Mig machines setup in our training area.
For all machines that are setup to run aluminium , there are 4 things that are required to be changed. These include, aluminium "U" groove drive rollers, a teflon low friction liner fitted to the Mig gun, Argon gas, and oversized tips (usually designated 1.2A). We recommend to use the most expensive welding wire that you can afford. Our preference is Safra 5356, 1.2mm diameter.

Single Phase Machines
Our machines of preference that we recommend for the home builder are, in order of preference, (1) The T&R Multi 250K Pulse Mig Welder and (2) The UniMIG Inverter Mig welder. Both of these machines are listed below.

3 Phase Machines
The preferred three phase welding machine is the Fronius TransPulse 2700. Please contact us if you require information or a quote on this machine.
