Buying a MIG welder
Key considerations
- What amperage machine is required to to do the job? Presume 35 to 40 amps per millimetre to be welded.
- What material will be welded? Pulse MIG produces the best results on aluminium & stainless.
- How easy is the interface on the machine to operate? Is it synergic and has it got memory settings?
- What is the duty cycle of the machine? Do you need a water cooled torch for heavy duty, time on applications.
- What is the wire drive system specification? 2 or 4 roll? Heavy duty block?
- What is the MIG torch specification & length? Torches up to 5 metres in length are available.
- What input power do you have available? You won't be able to weld above 6 mm material thickness on 240 volts.
- What long is the machine warranty ? Does the dealer have engineers, who can provide after sales back up.
240 volt Multi process MIG with Tool case
- The Fronius Transsteel 2200 is a true Multi process welding set with MIG, TIG, MMA capability. It's MIG side has synergic functionality up to 210 amps, whilst you can DC Pulse TIG @230 amps.
- With MMA stick welding up to 180 amps and arc force, Hot start & anti-stick technology to boot, it's the ideal tool for site work. Everything fits neatly in a tool case.
- The MIG wire feeder takes 100 or 200mm reels & switching between processes is easy.
240 volt MIG Inverter
- The Miller MPI 220P MIG is great for pulse mig welding up to 5mm steel & 6mm aluminium. Featuring a synergic mode, means it will select the correct voltage and amperage based on wire feed speed set up by the operator.
- This universal multi-process inverter can be used for DC TIG & MMA welding at 5 to 200 amps. Adjustable Hot start for stick & upslope/downslope function for TIG are a nice bonus.
- Great all rounder for site work, due it weighing only 16 kilos. Supplied with a Binzel MB25 4 metre air cooled torch, 230 amps @60%.
415 volt Compact Pulse MIG
- The Miller Migmatic 300IP is a portable, and compact pulse MIG welding machine, with an amperage range of 5 to 300 amps and 4 roll wire drive unit, compatible with 1.0mm-1.2mm wire.
- We like the 300IP's 4 pre-set trigger switch program & it's pulse MIG capabilities making it the ideal system for aluminium, stainless steel, and thin plate.
- Pulse reduces weld spatter & in turn post weld clean up. Supplied with a Binzel MB36 4 metre torch, welding up to 10mm material.
High Amp MIG seperate-Air Cooled
- The Foster MAXI 405 is ideal for medium to large fabrication work where a simple, strong and easy-to-use equipment is needed.
- The MAXI 405 has fine arc characteristics, a robust construction & good energy saving.
- The WF6 wire feed unit's digital ammeter/voltmeter have a hold function, which stores the last welding parameters.
- The Industrial 4 roll wire feed mechanism offers a precise and constant wire drive.
- The feeder has an inspection window on the spool cover, 2/4 STROKE selector switch, burn back & motor ramp adjustments for precise arc striking.
415 Volt Heavy duty water cooled MIG
- Our robust and reliable Foster Maxi 406i S MIG is also available in a water cooled version. The power sources boast active four roll wire feed systems, digital volt/amp meter and infinite current adjustment.
- These high quality machines are a rugged and reliable solution for high amp, demanding fabrication with the latest inverter technology providing a considerable energy saving against traditional transformer based sets.
Push-Pull for heavy duty Aluminium MIG welding
- When heavy duty MIG welding of aluminium is required and wire needs to be fed over long distances, the only viable welding method is Push-Pull MIG. Push-pull utilises two motors, one in the feeder & one in the gun, to feed MIG wire distances up to ten metres.
- Miller's Alumafeed push-pull system couples to the XMT350 Mpa synergic pulse power source & has few peers in the transport sector. Miller's robust XR30 pistol grip gun is available in air & water cooled versions & in lengths up to 10 metres and allows the operator to weld inside a structure or trailer with ease.
- Miller's synchronized, true push-pull wire feed systems have a slave/torque motor to ensure smooth, consistent feeding and improved arc performance, while reducing the problems normally associated with feeding aluminium.
