Find your welder in 6 questions
Answer six short questions about material, process, thickness, workload, power supply and budget, and we will show a first selection: three used machines from the Krotoszyn warehouse worth checking for your job.

Every unit is checked in our service workshop to current standards, with a load test in Krotoszyn. The price includes the first year of the basic service package. We ship across the whole European Union.
How to choose a welder for your workshop
Current depends on the joint, not on thickness alone
You cannot read the current straight off the plate thickness. The same 8 mm in a bevelled butt joint, in a fillet joint and in a fixed position needs different settings, and the process shifts them again, because MIG/MAG, TIG and MMA put heat into the joint in different ways. The duty cycle matters too: the current a machine holds through a short weld drops when the work runs on. That is why we set the current headroom after you describe the joint, the material and how many hours a day the machine has to pull.
230 or 400 V
A 230 V socket on its own does not decide which machine you can run. What counts is the circuit protection, the cross section and length of the cable, and on longer work the draw at the current you actually weld with. The maker states the draw for the rated current at a given duty cycle, so the same machine loads your installation differently on lighter work. Tell us your protection rating and how long your welds are, and we will check on the record of a specific unit whether it will run at your place without tripping the breaker.
MIG or TIG
MIG/MAG is faster and more forgiving, which is why it is taken for longer welds and for mild steel structures. TIG gives a narrow, clean weld and works better on thin sheet and stainless, only the job takes longer. On aluminium the choice depends on the thickness, the alloy and how clean the joint has to be: TIG usually with AC, while in MIG/MAG some jobs need pulse and others come out without it, given the right feeder, torch and gas. Describe the material, the alloy and the type of joint, and we will name the process together with the equipment it needs.
