Description

Ideal for all applications, they are equally happy working outside in the rain, in the back of a van or in your workshop. These are real ‘go anywhere weld anything’ machine & will run from a 230V 13A plug to around 170A output. Perfect for welding all types of metals, aluminium, aluminium alloys & castings, steel, stainless steel, hardox, duplex, copper, brass, titanium, etc.



Key Features:




  • Super smooth stable arc from 5 or 10 amps upwards on both AC & DC

  • Variable AC frequency 25hz-200hz

  • Extended AC balance control up to 95% neg through to 95% positive

  • Instant arc starting every time you press the torch switch

  • Electronic pulse HF (IT friendly so doesn’t affect your PC & phones etc)

  • Up slope & down slope controls for perfect weld starts & finishes

  • Post flow gas control for contamination free finishes

  • 2T standard torch trigger & 4T torch trigger latching

  • MMA ARC welding function welds all rods including cellulosic 6010 etc

  • MMA ARC welding with both DC & AC current

  • Digi meter shows preset then precise A when welding for EN1090 etc

  • Remote socket to accept foot control or torch amps control etc

  • Very simple to set up & use, anyone can use it in seconds

  • Built in automatic compensation for varying supply & long cables

  • Dual voltage input 230/400V, connect to single phase or 3 phase supply

  • Generator friendly design (even unstable generators are no problem)

  • Very efficient design to minimise power consumption

  • Suitable for use inside or outside (site welding etc) (IP23S rating)





DC TIG performance



On DC TIG the high OCV guarantees instant arc starts & is perfectly smooth, stable & quiet right through from min to max power. The output power is set precisely on the amps knob & shows on the digi meter prior to actually welding, when welding the actual value is displayed on the meter. Slope in & out gives perfect starts & finishes to every weld. Variable gas post flow control ensures coverage of shielding gas for the weld pool & electrode at the finish.





AC TIG performance



On AC TIG the arc starts instantly & is perfectly smooth & stable even at minimum amps. The output power is set precisely on the amps knob & shows on the digi metre prior to actually welding, when welding the actual value is displayed on the metre.



The extended AC balance control allows you to change the AC balance through an extended range & is a really useful feature. This can be set to any position from 95% negative for maximum heat into the weld pool right through to 95% positive for maximum cleaning effect. By running a high % of negative balance the heat input into the TIG torch is substantially reduced & the heat into the job increases significantly. This allows you tackle those thicker jobs like heavy castings and extends the range of the electrode so you can even run a 3.2 electrode with an air cooled torch up to 300A short term. The balance control also allows you to change the output from AC to DC – or DC+ output (reverse polarity). 



The variable AC frequency controls the heat spread of the arc, at low frequency’s such as 25hz the arc is soft & has a wide spread, as the frequency is increased the arc constricts to give a more focused narrow spread of heat. Again the slope controls & post flow gas control give perfect starts & finishes to every weld.
