    Use a strip of plywood or similar as a guide to run the side of the torch or nozzle along.

    The cutting tip on my Hypertherm is designed to be dragged along the work so it can be used with a straight-edge or template to guide the cut if required. Other makes may have the same ability.

    I always use a straight edge, but I still find if I'm in an awkward position, I can wander off the edge without being aware of it.

    My cheap-arsed CUT 40 machine is fine with having the tip dragged along the surface, but I notice some more expensive units require a gap, and typically provide an attachment to maintain the spacing. Haven't worked out what's different with these machines.

    I invested in a Tanjant straight-line guide and a circle guide, not cheap but good quality gear that's made in Melbourne & and sold world wide. I've got a MetalMaster 215 TIG/Plasma machine so I just added the insert that fits this torch. I tend to use it a lot for sheet metal cutting, beautiful clean cut as I can set cutting angles and height. Handy too for doing bevel cuts for thicker steel where multi-pass welding is required. The Tanjants come with suction pads as well the standard magnets so I can use them on stainless, aluminium etc where magnets don't work. I soon recovered the initial purchase cost in speed and accuracy.

    Been using the Aldi cutter again today. Had to cut some old brackets off my yard crane and fan new ones to fit a different steering box.
    A few layers of paint etc. Cut it OK, but struggles in the thicker radiused corner of 6mm angle.



    This 1.6mm painted sheet was like butter (freehand).



    Reasonably clean cut on 6mm

    Default Anyone know what the thread on the torch is?

    I have one of these (and I've cut 12mm steel with it, though it was rough as guts). Does fine in smaller stuff.

    I ordered a straight handpiece to convert to CNC, but the thread is not a match, though very close. Anyone know what the thread on the workzone is (where the air hose joins the torch, inside the torch handle)?

    Plasma Cutter
    You are a farmer. Would you buy your tractor from a grocery shop?
    For me its the same sort of argument with metal working equipment.

    If I purchase a machine I expect a longevity from it and the availability of spare parts. I may be wrong but would not expect it from Aldi.

    If the pricing is so good to enable it to be a throw away unit, it might be Ok, given that that cuts shown are comparable with an oxy acetylene plant.

    Welcome
